## Timelines Aggregation Jobs
This directory contains the specific definition of aggregate jobs that generate features used by the Heavy Ranker.
The primary files of interest are [`TimelinesAggregationConfigDetails.scala`](TimelinesAggregationConfigDetails.scala), which contains the defintion for the batch aggregate jobs and [`real_time/TimelinesOnlineAggregationConfigBase.scala`](real_time/TimelinesOnlineAggregationConfigBase.scala) which contains the definitions for the real time aggregate jobs.
The aggregation framework that these jobs are based on is [here](../../../../../../../../timelines/data_processing/ml_util/aggregation_framework).

## Prediction Features
This directory contains a collection of `Features` (`com.twitter.ml.api.Feature`) which are definitions of feature names and datatypes which allow the features to be efficiently processed and passed to the different ranking models.
By predefining the features with their names and datatypes, when features are being generated, scribed or used to score they can be identified with only a hash of their name.
Not all of these features are used in the model, many are experimental or deprecated.

* Gets translated into multiple strongly typed TypedAggregateGroup(s)
* by the buildTypedAggregateGroups() method defined below.
*
* @param inputSource Source to compute this aggregate over
* @param preTransforms Sequence of [[ITransform]] that is applied to
* data records pre-aggregation (e.g. discretization, renaming)
* @param samplingTransformOpt Optional [[OneToSomeTransform]] that samples data record
* @param aggregatePrefix Prefix to use for naming resultant aggregate features
* @param keys Features to group by when computing the aggregates
* (e.g. USER_ID, AUTHOR_ID). These must be either discrete, string or sparse binary.
* Grouping by a sparse binary feature is different than grouping by a discrete or string
* feature. For example, if you have a sparse binary feature WORDS_IN_TWEET which is
* a set of all words in a tweet, then grouping by this feature generates a
* separate aggregate mean/count/etc for each value of the feature (each word), and
* not just a single aggregate count for different "sets of words"
* @param features Features to aggregate (e.g. blender_score or is_photo).
* @param labels Labels to cross the features with to make pair features, if any.
* @param metrics Aggregation metrics to compute (e.g. count, mean)
* @param halfLives Half lives to use for the aggregations, to be crossed with the above.
* use Duration.Top for "forever" aggregations over an infinite time window (no decay).
* @param outputStore Store to output this aggregate to
* @param includeAnyFeature Aggregate label counts for any feature value
* @param includeAnyLabel Aggregate feature counts for any label value (e.g. all impressions)
* @param includeTimestampFeature compute max aggregate on timestamp feature
* @param aggExclusionRegex Sequence of Regexes, which define features to

* Case class that represents the "grouping" key for any aggregate feature.
* Used by Summingbird to output aggregates to the key-value "store" using sumByKey()
*
* @discreteFeaturesById All discrete featureids (+ values) that are part of this key
* @textFeaturesById All string featureids (+ values) that are part of this key
*
* Example 1: the user aggregate features in aggregatesv1 all group by USER_ID,
* which is a discrete feature. When storing these features, the key would be:
*
* discreteFeaturesById = Map(hash(USER_ID) -> <the actual user id>), textFeaturesById = Map()
*
* Ex 2: If aggregating grouped by USER_ID, AUTHOR_ID, tweet link url, the key would be:
*
* discreteFeaturesById = Map(hash(USER_ID) -> <actual user id>, hash(AUTHOR_ID) -> <actual author id>),
* textFeaturesById = Map(hash(URL_FEATURE) -> <the link url>)
*
* I could have just used a DataRecord for the key, but I wanted to make it strongly typed
* and only support grouping by discrete and string features, so using a case class instead.
*
* Re: efficiency, storing the hash of the feature in addition to just the feature value
* is somewhat more inefficient than only storing the feature value in the key, but it
* adds flexibility to group multiple types of aggregates in the same output store. If we

Overview
========
The **aggregation framework** is a set of libraries and utilities that allows teams to flexibly
compute aggregate (counting) features in both batch and in real-time. Aggregate features can capture
historical interactions between on arbitrary entities (and sets thereof), conditional on provided features
and labels.
These types of engineered aggregate features have proven to be highly impactful across different teams at Twitter.
What are some features we can compute?
--------------------------------------
The framework supports computing aggregate features on provided grouping keys. The only constraint is that these keys are sparse binary features (or are sets thereof).
For example, a common use case is to calculate a user's past engagement history with various types of tweets (photo, video, retweets, etc.), specific authors, specific in-network engagers or any other entity the user has interacted with and that could provide signal. In this case, the underlying aggregation keys are `userId`, `(userId, authorId)` or `(userId, engagerId)`.
In Timelines and MagicRecs, we also compute custom aggregate engagement counts on every `tweetId`. Similary, other aggregations are possible, perhaps on `advertiserId` or `mediaId` as long as the grouping key is sparse binary.
What implementations are supported?
-----------------------------------
Offline, we support the daily batch processing of DataRecords containing all required input features to generate
aggregate features. These are then uploaded to Manhattan for online hydration.
Online, we support the real-time aggregation of DataRecords through Storm with a backing memcache that can be queried
for the real-time aggregate features.
Additional documentation exists in the [docs folder](docs)
Where is this used?
--------------------
The Home Timeline heavy ranker uses a varierty of both [batch and real time features](../../../../src/scala/com/twitter/timelines/prediction/common/aggregates/README.md) generated by this framework.
These features are also used for email and other recommendations.

* @param featuresToAggregate Features to aggregate (e.g. blender_score or is_photo)
* @param labels Labels to cross the features with to make pair features, if any.

* @param metrics Aggregation metrics to compute (e.g. count, mean)

* @param outputStore Store to output this aggregate to
* @param includeAnyFeature Aggregate label counts for any feature value
* @param includeAnyLabel Aggregate feature counts for any label value (e.g. all impressions)
*
* The overall config for the summingbird job consists of a list of "AggregateGroup"
* case class objects, which get translated into strongly typed "TypedAggregateGroup"
* case class objects. A single TypedAggregateGroup always groups input data records from
* ''inputSource'' by a single set of aggregation keys (''featuresToAggregate'').
* Within these groups, we perform a comprehensive cross of:
*
* ''featuresToAggregate'' x ''labels'' x ''metrics'' x ''halfLives''
*
* All the resultant aggregate features are assigned a human-readable feature name
* beginning with ''aggregatePrefix'', and are written to DataRecords that get
* aggregated and written to the store specified by ''outputStore''.
*
* Illustrative example. Suppose we define our spec as follows:
*
* TypedAggregateGroup(
* inputSource = "timelines_recap_daily",
* aggregatePrefix = "user_author_aggregate",
* keysToAggregate = Set(USER_ID, AUTHOR_ID),
* featuresToAggregate = Set(RecapFeatures.TEXT_SCORE, RecapFeatures.BLENDER_SCORE),
* labels = Set(RecapFeatures.IS_FAVORITED, RecapFeatures.IS_REPLIED),
* metrics = Set(CountMetric, MeanMetric),
* halfLives = Set(7.Days, 30.Days),
* outputStore = "user_author_aggregate_store"
* )
*
* This will process data records from the source named "timelines_recap_daily"
* (see AggregateSource.scala for more details on how to add your own source)
* It will produce a total of 2x2x2x2 = 16 aggregation features, named like:
*
* user_author_aggregate.pair.recap.engagement.is_favorited.recap.searchfeature.blender_score.count.7days
* user_author_aggregate.pair.recap.engagement.is_favorited.recap.searchfeature.blender_score.count.30days
* user_author_aggregate.pair.recap.engagement.is_favorited.recap.searchfeature.blender_score.mean.7days
*
* ... (and so on)
*
* and all the result features will be stored in DataRecords, summed up, and written
* to the output store defined by the name "user_author_aggregate_store".
* (see AggregateStore.scala for details on how to add your own store).
*
* If you do not want a full cross, split up your config into multiple TypedAggregateGroup
* objects. Splitting is strongly advised to avoid blowing up and creating invalid

/**
* When using the aggregates framework to group by sparse binary keys,
* we generate different aggregate feature values for each possible
* value of the sparse key. Hence, when joining back the aggregate
* features with a training data set, each individual training record
* has multiple aggregate features to choose from, for each value taken
* by the sparse key(s) in the training record. The merge policy trait
* below specifies how to condense/combine this variable number of
* aggregate features into a constant number of features for training.
* Some simple policies might be: pick the first feature set (randomly),
* pick the top sorted by some attribute, or take some average.
*
* Example: suppose we group by (ADVERTISER_ID, INTEREST_ID) where INTEREST_ID
* is the sparse key, and compute a "CTR" aggregate feature for each such
* pair measuring the click through rate on ads with (ADVERTISER_ID, INTEREST_ID).
* Say we have the following aggregate records:
*
* (ADVERTISER_ID = 1, INTEREST_ID = 1, CTR = 5%)
* (ADVERTISER_ID = 1, INTEREST_ID = 2, CTR = 15%)
* (ADVERTISER_ID = 2, INTEREST_ID = 1, CTR = 1%)
* (ADVERTISER_ID = 2, INTEREST_ID = 2, CTR = 10%)
* ...
* At training time, each training record has one value for ADVERTISER_ID, but it
* has multiple values for INTEREST_ID e.g.
*
* (ADVERTISER_ID = 1, INTEREST_IDS = (1,2))
*
* There are multiple potential CTRs we can get when joining in the aggregate features:
* in this case 2 values (5% and 15%) but in general it could be many depending on how
* many interests the user has. When joining back the CTR features, the merge policy says how to
* combine all these CTRs to engineer features.
*
* "Pick first" would say - pick some random CTR (whatever is first in the list, maybe 5%)
* for training (probably not a good policy). "Sort by CTR" could be a policy
* that just picks the top CTR and uses it as a feature (here 15%). Similarly, you could
* imagine "Top K sorted by CTR" (use both 5 and 15%) or "Avg CTR" (10%) or other policies,
* all of which are defined as objects/case classes that override this trait.

.. _aggregation:
Core Concepts
=============
This page provides an overview of the aggregation framework and goes through examples on how to define aggregate features. In general, we can think of an aggregate feature as a grouped set of records, on which we incrementally update the aggregate feature values, crossed by the provided features and conditional on the provided labels.
AggregateGroup
--------------
An `AggregateGroup` defines a single unit of aggregate computation, similar to a SQL query. These are executed by the underlying jobs (internally, a `DataRecordAggregationMonoid <https://cgit.twitter.biz/source/tree/timelines/data_processing/ml_util/aggregation_framework/DataRecordAggregationMonoid.scala#n42>`_ is applied to `DataRecords` that contain the features to aggregate). Many of these groups can exist to define different types of aggregate features.
Let's start with the following examples of an `AggregateGroup` to discuss the meaning of each of its constructor arguments:
.. code-block:: scala
val UserAggregateStore = "user_aggregates"
val aggregatesToCompute: Set[TypedAggregateGroup[_]] = Set(
AggregateGroup(
inputSource = timelinesDailyRecapSource,
aggregatePrefix = "user_aggregate_v2",
preTransformOpt = Some(RemoveUserIdZero),
keys = Set(USER_ID),
features = Set(HAS_PHOTO),
labels = Set(IS_FAVORITED),
metrics = Set(CountMetric, SumMetric),
halfLives = Set(50.days),
outputStore = OfflineAggregateStore(
name = UserAggregateStore,
startDate = "2016-07-15 00:00",
commonConfig = timelinesDailyAggregateSink,
batchesToKeep = 5
)
)
.flatMap(_.buildTypedAggregateGroups)
)
This `AggregateGroup` computes the number of times each user has faved a tweet with a photo. The aggregate count is decayed with a 50 day halflife.
Naming and preprocessing
------------------------
`UserAggregateStore` is a string val that acts as a scope of a "root path" to which this group of aggregate features will be written. The root path is provided separately by the implementing job.
`inputSource` defines the input source of `DataRecords` that we aggregate on. These records contain the relevant features required for aggregation.
`aggregatePrefix` tells the framework what prefix to use for the aggregate features it generates. A descriptive naming scheme with versioning makes it easier to maintain features as you add or remove them over the long-term.
`preTransforms` is a `Seq[com.twitter.ml.api.ITransform] <https://cgit.twitter.biz/source/tree/src/java/com/twitter/ml/api/ITransform.java>`_ that can be applied to the data records read from the input source before they are fed into the `AggregateGroup` to apply aggregation. These transforms are optional but can be useful for certain preprocessing operations for a group's raw input features.
.. admonition:: Examples
You can downsample input data records by providing `preTransforms`. In addition, you could also join different input labels (e.g. "is_push_openend" and "is_push_favorited") and transform them into a combined label that is their union ("is_push_engaged") on which aggregate counts will be calculated.
Keys
----
`keys` is a crucial field in the config. It defines a `Set[com.twitter.ml.api.Feature]` which specifies a set of grouping keys to use for this `AggregateGroup`.
Keys can only be of 3 supported types currently: `DISCRETE`, `STRING` and `SPARSE_BINARY`. Using a discrete or a string/text feature as a key specifies the unit to group records by before applying counting/aggregation operators.
.. admonition:: Examples
.. cssclass:: shortlist
#. If the key is `USER_ID`, this tells the framework to group all records by `USER_ID`, and then apply aggregations (sum/count/etc) within each user’s data to generate aggregate features for each user.
#. If the key is `(USER_ID, AUTHOR_ID)`, then the `AggregateGroup` will output features for each unique user-author pair in the input data.
#. Finally, using a sparse binary feature as key has special "flattening" or "flatMap" like semantics. For example, consider grouping by `(USER_ID, AUTHOR_INTEREST_IDS)` where `AUTHOR_INTEREST_IDS` is a sparse binary feature which represents a set of topic IDs the author may be tweeting about. This creates one record for each `(user_id, interest_id)` pair - so each record with multiple author interests is flattened before feeding it to the aggregation.
Features
--------
`features` specifies a `Set[com.twitter.ml.api.Feature]` to aggregate within each group (defined by the keys specified earlier).
We support 2 types of `features`: `BINARY` and `CONTINUOUS`.
The semantics of how the aggregation works is slightly different based on the type of “feature”, and based on the “metric” (or aggregation operation):
.. cssclass:: shortlist
#. Binary Feature, Count Metric: Suppose we have a binary feature `HAS_PHOTO` in this set, and are applying the “Count” metric (see below for more details on the metrics), with key `USER_ID`. The semantics is that this computes a feature which measures the count of records with `HAS_PHOTO` set to true for each user.
#. Binary Feature, Sum Metric - Does not apply. No feature will be computed.
#. Continuous Feature, Count Metric - The count metric treats all features as binary features ignoring their value. For example, suppose we have a continuous feature `NUM_CHARACTERS_IN_TWEET`, and key `USER_ID`. This measures the count of records that have this feature `NUM_CHARACTERS_IN_TWEET` present.
#. Continuous Feature, Sum Metric - In the above example, the features measures the sum of (num_characters_in_tweet) over all a user’s records. Dividing this sum feature by the count feature would give the average number of characters in all tweets.
.. admonition:: Unsupported feature types
`DISCRETE` and `SPARSE` features are not supported by the Sum Metric, because there is no meaning in summing a discrete feature or a sparse feature. You can use them with the CountMetric, but they may not do what you would expect since they will be treated as binary features losing all the information within the feature. The best way to use these is as “keys” and not as “features”.
.. admonition:: Setting includeAnyFeature
If constructor argument `includeAnyFeature` is set, the framework will append a feature with scope `any_feature` to the set of all features you define. This additional feature simply measures the total count of records. So if you set your features to be equal to Set.empty, this will measure the count of records for a given `USER_ID`.
Labels
------
`labels` specifies a set of `BINARY` features that you can cross with, prior to applying aggregations on the `features`. This essentially restricts the aggregate computation to a subset of the records within a particular key.
We typically use this to represent engagement labels in an ML model, in this case, `IS_FAVORITED`.
In this example, we are grouping by `USER_ID`, the feature is `HAS_PHOTO`, the label is `IS_FAVORITED`, and we are computing `CountMetric`. The system will output a feature for each user that represents the number of favorites on tweets having photos by this `userId`.
.. admonition:: Setting includeAnyLabel
If constructor argument `includeAnyLabel` is set (as it is by default), then similar to `any_feature`, the framework automatically appends a label of type `any_label` to the set of all labels you define, which represents not applying any filter or cross.
In this example, `any_label` and `any_feature` are set by default and the system would actually output 4 features for each `user_id`:
.. cssclass:: shortlist
#. The number of `IS_FAVORITED` (favorites) on tweet impressions having `HAS_PHOTO=true`
#. The number of `IS_FAVORITED` (favorites) on all tweet impressions (`any_feature` aggregate)
#. The number of tweet impressions having `HAS_PHOTO=true` (`any_label` aggregate)
#. The total number of tweet impressions for this user id (`any_feature.any_label` aggregate)
.. admonition:: Disabling includeAnyLabel
To disable this automatically generated feature you can use `includeAnyLabel = false` in your config. This will remove some useful features (particularly for counterfactual signal), but it can greatly save on space since it does not store every possible impressed set of keys in the output store. So use this if you are short on space, but not otherwise.
Metrics
-------
`metrics` specifies the aggregate operators to apply. The most commonly used are `Count`, `Sum` and `SumSq`.
As mentioned before, `Count` can be applied to all types of features, but treats every feature as binary and ignores the value of the feature. `Sum` and `SumSq` can only be applied to Continuous features - they will ignore all other features you specify. By combining sum and sumsq and count, you can produce powerful “z-score” features or other distributional features using a post-transform.
It is also possible to add your own aggregate operators (e.g. `LastResetMetric <https://phabricator.twitter.biz/D228537>`_) to the framework with some additional work.
HalfLives
---------
`halfLives` specifies how fast aggregate features should be decayed. It is important to note that the framework works on an incremental basis: in the batch implementation, the summingbird-scalding job takes in the most recently computed aggregate features, processed on data until day `N-1`, then reads new data records for day `N` and computes updated values of the aggregate features. Similarly, the decay of real-time aggregate features takes the actual time delta between the current time and the last time the aggregate feature value was updated.
The halflife `H` specifies how fast to decay old sums/counts to simulate a sliding window of counts. The implementation is such that it will take `H` amount of time to decay an aggregate feature to half its initial value. New observed values of sums/counts are added to the aggregate feature value.
.. admonition:: Batch and real-time
In the batch use case where aggregate features are recomputed on a daily basis, we typically take halflives on the order of weeks or longer (in Timelines, 50 days). In the real-time use case, shorter halflives are appropriate (hours) since they are updated as client engagements are received by the summingbird job.
SQL Equivalent
--------------
Conceptually, you can also think of it as:
.. code-block:: sql
INSERT INTO <outputStore>.<aggregatePrefix>
SELECT AGG(<features>) /* AGG is <metrics>, which is a exponentially decaying SUM or COUNT etc. based on the halfLifves */
FROM (
SELECT preTransformOpt(*) FROM <inputSource>
)
GROUP BY <keys>
WHERE <labels> = True
any_features is AGG(*).
any_labels removes the WHERE clause.

.. _batch:
Batch aggregate feature jobs
============================
In the previous section, we went over the core concepts of the aggregation framework and discussed how you can set up you own `AggregateGroups` to compute aggregate features.
Given these groups, this section will discuss how you can setup offline batch jobs to produce the corresponding aggregate features, updated daily. To accomplish this, we need to setup a summingbird-scalding job that is pointed to the input data records containing features and labels to be aggregated.
Input Data
----------
In order to generate aggregate features, the relevant input features need to be available offline as a daily scalding source in `DataRecord` format (typically `DailySuffixFeatureSource <https://cgit.twitter.biz/source/tree/src/scala/com/twitter/ml/api/FeatureSource.scala>`_, though `HourlySuffixFeatureSource` could also be usable but we have not tested this).
.. admonition:: Note
The input data source should contain the keys, features and labels you want to use in your `AggregateGroups`.
Aggregation Config
------------------
Now that we have a daily data source with input features and labels, we need to setup the `AggregateGroup` config itself. This contains all aggregation groups that you would like to compute and we will go through the implementation step-by-step.
.. admonition:: Example: Timelines Quality config
`TimelinesAggregationConfig <https://cgit.twitter.biz/source/tree/src/scala/com/twitter/timelines/prediction/common/aggregates/TimelinesAggregationConfig.scala>`_ imports the configured `AggregationGroups` from `TimelinesAggregationConfigDetails <https://cgit.twitter.biz/source/tree/src/scala/com/twitter/timelines/prediction/common/aggregates/TimelinesAggregationConfigDetails.scala>`_. The config is then referenced by the implementing summingbird-scalding job which we will setup below.
OfflineAggregateSource
----------------------
Each `AggregateGroup` will need to define a (daily) source of input features. We use `OfflineAggregateSource` for this to tell the aggregation framework where the input data set is and the required timestamp feature that the framework uses to decay aggregate feature values:
.. code-block:: scala
val timelinesDailyRecapSource = OfflineAggregateSource(
name = "timelines_daily_recap",
timestampFeature = TIMESTAMP,
scaldingHdfsPath = Some("/user/timelines/processed/suggests/recap/data_records"),
scaldingSuffixType = Some("daily"),
withValidation = true
)
.. admonition:: Note
.. cssclass:: shortlist
#. The name is not important as long as it is unique.
#. `timestampFeature` must be a discrete feature of type `com.twitter.ml.api.Feature[Long]` and represents the “time” of a given training record in milliseconds - for example, the time at which an engagement, push open event, or abuse event took place that you are trying to train on. If you do not already have such a feature in your daily training data, you need to add one.
#. `scaldingSuffixType` can be “hourly” or “daily” depending on the type of source (`HourlySuffixFeatureSource` vs `DailySuffixFeatureSource`).
#. Set `withValidation` to true to validate the presence of _SUCCESS file. Context: https://jira.twitter.biz/browse/TQ-10618
Output HDFS store
-----------------
The output HDFS store is where the computed aggregate features are stored. This store contains all computed aggregate feature values and is incrementally updated by the aggregates job every day.
.. code-block:: scala
val outputHdfsPath = "/user/timelines/processed/aggregates_v2"
val timelinesOfflineAggregateSink = new OfflineStoreCommonConfig {
override def apply(startDate: String) = new OfflineAggregateStoreCommonConfig(
outputHdfsPathPrefix = outputHdfsPath,
dummyAppId = "timelines_aggregates_v2_ro", // unused - can be arbitrary
dummyDatasetPrefix = "timelines_aggregates_v2_ro", // unused - can be arbitrary
startDate = startDate
)
}
Note: `dummyAppId` and `dummyDatasetPrefix` are unused so can be set to any arbitrary value. They should be removed on the framework side.
The `outputHdfsPathPrefix` is the only field that matters, and should be set to the HDFS path where you want to store the aggregate features. Make sure you have a lot of quota available at that path.
Setting Up Aggregates Job
-------------------------
Once you have defined a config file with the aggregates you would like to compute, the next step is to create the aggregates scalding job using the config (`example <https://cgit.twitter.biz/source/tree/timelines/data_processing/ad_hoc/aggregate_interactions/v2/offline_aggregation/TimelinesAggregationScaldingJob.scala>`_). This is very concise and requires only a few lines of code:
.. code-block:: scala
object TimelinesAggregationScaldingJob extends AggregatesV2ScaldingJob {
override val aggregatesToCompute = TimelinesAggregationConfig.aggregatesToCompute
}
Now that the scalding job is implemented with the aggregation config, we need to setup a capesos config similar to https://cgit.twitter.biz/source/tree/science/scalding/mesos/timelines/prod.yml:
.. code-block:: scala
# Common configuration shared by all aggregates v2 jobs
__aggregates_v2_common__: &__aggregates_v2_common__
class: HadoopSummingbirdProducer
bundle: offline_aggregation-deploy.tar.gz
mainjar: offline_aggregation-deploy.jar
pants_target: "bundle timelines/data_processing/ad_hoc/aggregate_interactions/v2/offline_aggregation:bin"
cron_collision_policy: CANCEL_NEW
use_libjar_wild_card: true
.. code-block:: scala
# Specific job computing user aggregates
user_aggregates_v2:
<<: *__aggregates_v2_common__
cron_schedule: "25 * * * *"
arguments: --batches 1 --output_stores user_aggregates --job_name timelines_user_aggregates_v2
.. admonition:: Important
Each AggregateGroup in your config should have its own associated offline job which specifies `output_stores` pointing to the output store name you defined in your config.
Running The Job
---------------
When you run the batch job for the first time, you need to add a temporary entry to your capesos yml file that looks like this:
.. code-block:: scala
user_aggregates_v2_initial_run:
<<: *__aggregates_v2_common__
cron_schedule: "25 * * * *"
arguments: --batches 1 --start-time “2017-03-03 00:00:00” --output_stores user_aggregates --job_name timelines_user_aggregates_v2
.. admonition:: Start Time
The additional `--start-time` argument should match the `startDate` in your config for that AggregateGroup, but in the format `yyyy-mm-dd hh:mm:ss`.
To invoke the initial run via capesos, we would do the following (in Timelines case):
.. code-block:: scala
CAPESOSPY_ENV=prod capesospy-v2 update --build_locally --start_cron user_aggregates_v2_initial_run science/scalding/mesos/timelines/prod.yml
Once it is running smoothly, you can deschedule the initial run job and delete the temporary entry from your production yml config.
.. code-block:: scala
aurora cron deschedule atla/timelines/prod/user_aggregates_v2_initial_run
Note: deschedule it preemptively to avoid repeatedly overwriting the same initial results
Then schedule the production job from jenkins using something like this:
.. code-block:: scala
CAPESOSPY_ENV=prod capesospy-v2 update user_aggregates_v2 science/scalding/mesos/timelines/prod.yml
All future runs (2nd onwards) will use the permanent entry in the capesos yml config that does not have the `start-time` specified.
.. admonition:: Job name has to match
It's important that the production run should share the same `--job_name` with the initial_run so that eagleeye/statebird knows how to keep track of it correctly.
Output Aggregate Features
-------------------------
This scalding job using the example config from the earlier section would output a VersionedKeyValSource to `/user/timelines/processed/aggregates_v2/user_aggregates` on HDFS.
Note that `/user/timelines/processed/aggregates_v2` is the explicitly defined root path while `user_aggregates` is the output directory of the example `AggregateGroup` defined earlier. The latter can be different for different `AggregateGroups` defined in your config.
The VersionedKeyValSource is difficult to use directly in your jobs/offline trainings, but we provide an adapted source `AggregatesV2FeatureSource` that makes it easy to join and use in your jobs:
.. code-block:: scala
import com.twitter.timelines.data_processing.ml_util.aggregation_framework.conversion._
val pipe: DataSetPipe = AggregatesV2FeatureSource(
rootPath = "/user/timelines/processed/aggregates_v2",
storeName = "user_aggregates",
aggregates = TimelinesAggregationConfig.aggregatesToCompute,
trimThreshold = 0
)(dateRange).read
Simply replace the `rootPath`, `storeName` and `aggregates` object to whatever you defined. The `trimThreshold` tells the framework to trim all features below a certain cutoff: 0 is a safe default to use to begin with.
.. admonition:: Usage
This can now be used like any other `DataSetPipe` in offline ML jobs. You can write out the features to a `DailySuffixFeatureSource`, you can join them with your data offline for trainings, or you can write them to a Manhattan store for serving online.
Aggregate Features Example
--------------------------
Here is an example of sample of the aggregate features we just computed:
.. code-block:: scala
user_aggregate_v2.pair.any_label.any_feature.50.days.count: 100.0
user_aggregate_v2.pair.any_label.tweetsource.is_quote.50.days.count: 30.0
user_aggregate_v2.pair.is_favorited.any_feature.50.days.count: 10.0
user_aggregate_v2.pair.is_favorited.tweetsource.is_quote.50.days.count: 6.0
meta.user_id: 123456789
Aggregate feature names match a `prefix.pair.label.feature.half_life.metric` schema and correspond to what was defined in the aggregation config for each of these fields.
.. admonition:: Example
In this example, the above features are capturing that userId 123456789L has:
..
A 50-day decayed count of 100 training records with any label or feature (“tweet impressions”)
A 50-day decayed count of 30 records that are “quote tweets” (tweetsource.is_quote = true)
A 50-day decayed count of 10 records that are favorites on any type of tweet (is_favorited = true)
A 50-day decayed count of 6 records that are “favorites” on “quote tweets” (both of the above are true)
By combining the above, a model might infer that for this specific user, quote tweets comprise 30% of all impressions, have a favorite rate of 6/30 = 20%, compared to a favorite rate of 10/100 = 10% on the total population of tweets.
Therefore, being a quote tweet makes this specific user `123456789L` approximately twice as likely to favorite the tweet, which is useful for prediction and could result in the ML model giving higher scores to & ranking quote tweets higher in a personalized fashion for this user.
Tests for Feature Names
--------------------------
When you change or add AggregateGroup, feature names might change. And the Feature Store provides a testing mechanism to assert that the feature names change as you expect. See `tests for feature names <https://docbird.twitter.biz/ml_feature_store/catalog.html#tests-for-feature-names>`_.
