R-Ladies Columbus Monthly Meetup

Sentiment Analysis!
___________________________________________________________________________________
The Objective is to create a neural network that can predict if a given movie review is positive or negative. This type of computation is also called Sentiment Analysis.

I will be working with “IMDB data-set”, a set of 50,000 reviews from the Internet Movie Database. They are split into 25,000 reviews for training and 25,000 reviews for testing, each set consisting in 50% negative and 50% positive reviews.

I will use Keras library to build neural network and walk you through building and training model, model tuning with different hyper-parameter (Optimizer, Loss Function, No. of layers, epoch, batch_size ). I will try and improve the accuracy of model by experimenting with different hyper-parameters.

Please come with a machine that can access rstudio.cloud. We will share link to project prior to session.

As always pizza and soft drinks will be available courtesy of our great local supporter, the Columbus Collaboratory.

Parking: Park in any spot marked "Reserved for the Columbus Collaboratory". There should be more than enough available- all are free. If you find that these spots are filled - park anywhere in surrounding lots See pics below for directions.
