Movie-Sentiment-Classifier

A movie review sentiment classifier based on the IMDB ratings dataset from Stanford.

See a demo of the model in an app here: http://www.jlbdatasci.com/jobs/review/

Stochastic Gradient Descent is a great option for building data science web apps, where new data is constantly coming in (IOT is a use-case too) and for processing large amounts of data on a single machine.

Requirements

Assuming you have sklearn installed:

1. Install Pyprind (conda/pip install pyprind)

Install

1. After cloning/uzipping file, unzip DATA\ratings_shuffled.zip into DATA\

Use

From Command line:

1. Navigate to project folder that contains sgd_movie_classifier
2. Run command: python sgd_movie_classifier.py

Otherwise, load in your favorite IDE.

Once the model is built, you can use the model in your own app. See link above to see this model in action.
