+# Pushservice
+
+Pushservice is the main push recommendation service at Twitter used to generate recommendation-based notifications for users. It currently powers two functionalities:
+
+- RefreshForPushHandler: This handler determines whether to send a recommendation push to a user based on their ID. It generates the best push recommendation item and coordinates with downstream services to deliver it
+- SendHandler: This handler determines and manage whether send the push to users based on the given target user details and the provided push recommendation item
+
+## Overview
+
+### RefreshForPushHandler
+
+RefreshForPushHandler follows these steps:
+
+- Building Target and checking eligibility
+    - Builds a target user object based on the given user ID
+    - Performs target-level filterings to determine if the target is eligible for a recommendation push
+- Fetch Candidates
+    - Retrieves a list of potential candidates for the push by querying various candidate sources using the target
+- Candidate Hydration
+    - Hydrates the candidate details with batch calls to different downstream services.
+- Pre-rank Filtering, also called Light Filtering
+    - Filters the hydrated candidates with lightweight RPC calls.
+- Rank
+    - Perform feature hydration for candidates and target user
+    - Performs light ranking on candidates
+    - Performs heavy ranking on candidates
+- Take Step, also called Heavy Filtering
+    - Takes the top-ranked candidates one by one and applies heavy filtering until one candidate passes all filter steps
+- Send
+    - Calls the appropriate downstream service to deliver the eligible candidate as a push and in-app notification to the target user
+
+### SendHandler
+
+SendHandler follows these steps:
+
+- Building Target
+    - Builds a target user object based on the given user ID
+- Candidate Hydration
+    - Hydrates the candidate details with batch calls to different downstream services.
+- Feature Hydration
+    - Perform feature hydration for candidates and target user
+- Take Step, also called Heavy Filtering
+    - Perform filterings and validation checking for the given candidate
+- Send
+    - Calls the appropriate downstream service to deliver the given candidate as a push and/or in-app notification to the target user

+# Notification Heavy Ranker Model
+
+## Model Context
+There are 4 major components of Twitter notifications recommendation system: 1) candidate generation 2) light ranking 3) heavy ranking & 4) quality control. This notification heavy ranker model is the core ranking model for the personalised notifications recommendation. It's a multi-task learning model to predict the probabilities that the target users will open and engage with the sent notifications.

+# Notification Light Ranker Model
+
+## Model Context
+There are 4 major components of Twitter notifications recommendation system: 1) candidate generation 2) light ranking 3) heavy ranking & 4) quality control. This notification light ranker model bridges candidate generation and heavy ranking by pre-selecting highly-relevant candidates from the initial huge candidate pool. It’s a light-weight model to reduce system cost during heavy ranking without hurting user experience.
+
+## Directory Structure
+- BUILD: this file defines python library dependencies
+- model_pools_mlp.py: this file defines tensorflow model architecture for the notification light ranker model
+- deep_norm.py: this file contains 1) how to build the tensorflow graph with specified model architecture, loss function and training configuration. 2) how to set up the overall model training & evaluation pipeline
+- eval_model.py: the main python entry file to set up the overall model evaluation pipeline
