Build A Chinese Movie Sentiment Classifier with Keras and Google Cloud ML Engine

This is source project for my sharing on GDG HK DevFest 2017. This project will show how we can run Keras cloud on both local development machine and Google Cloud ML Engine. A simple character level CNN model is built using Keras.

Prerequisites

Install gcloud
Install the python dependencies. pip install --upgrade -r requirements.txt

Scripts

Train, TensorBoard and Predict

gcloud-train-*.sh
- Scripts for training the model locally or on Google Cloud ML Engine
gcloud-tensorboard-*.sh
- Scripts for visualizing the training process locally or on Google Cloud ML Engine
gcloud-predict-*.sh
- Scripts for making prediction locally or on Google Cloud ML Engine

Billing

If you concern how much money will be burned using Google Cloud ML Engine, the answer is less than US$1 for this project. The model is simple and we don't have much dataset. So it is very safe to play around and have fun.

For you to try out

Change the model hidden_dims to larger (64) or even larger value
Use one-hot encoding instead of the embedding layer
Change CNN to LSTM model

Changes

Predicting income => predicting Movie Sentiment
Added multiple runs support for TensorBoard
Fixed for "You must feed a value for placeholder tensor keras_learning_phase with dtype uint8"
Packed commands into shell scripts
