Project Overview:

In this research paper we apply the methodology outlined in the arXiv working paper: ”Joint Deep Modeling of Users and Items Using Reviews for Recommendation” for rating prediction of movies using the Amazon Instant Video data set and GloVe.6B 50 dimensional word embeddings. Of the data set there are only 18,000 text reviews. The approach used in this paper models users and items jointly using review text in two cooperative neural networks.

Before attempting to train the networks as provided in this repository, the user must preprocess the amazon instant video dataset. The goal of this process is for one data point to contain all of the users reviews (excluding the review for the current movie), all of the movie's reviews (excluding that written by the current user), and the associated rating. We have provided some notebooks and examples in the Preprocessing directory that may be useful.

Because one of the primary goals of our project was to explore the effectiveness of different sequential data modeling neural network layers, it was natural to split the code base into three different source files corresponding with the three different layers we analyzed.

Before training any of these models the data is split into training and testing sets. In this case, the sets are not a simple shuffle of the dataset because we do not want our network to ever see users or items that appear in the test set prior to test. We therefore use the following approach:

  1. get all unique reviewers
  2. extract the unique reviewers' data points to a test set
  3. place all remaining data points in a training set
  4. from the test set get a set of unique movies
  5. remove all entries with these movies from the training set

Following this procedure requires us to discard some data, but means that our testing set is entirely independent of the training set.

Project Overview:

In this research paper we apply the methodology outlined in the arXiv working paper: ”Joint Deep Modeling of Users and Items Using Reviews for Recommendation” for rating prediction of movies using the Amazon Instant Video data set and GloVe.6B 50 dimensional word embeddings. Of the data set there are only 18,000 text reviews. The approach used in this paper models users and items jointly using review text in two cooperative neural networks.

Before attempting to train the networks as provided in this repository, the user must preprocess the amazon instant video dataset. The goal of this process is for one data point to contain all of the users reviews (excluding the review for the current movie), all of the movie's reviews (excluding that written by the current user), and the associated rating. We have provided some notebooks and examples in the Preprocessing directory that may be useful.

Because one of the primary goals of our project was to explore the effectiveness of different sequential data modeling neural network layers, it was natural to split the code base into three different source files corresponding with the three different layers we analyzed.

Before training any of these models the data is split into training and testing sets. In this case, the sets are not a simple shuffle of the dataset because we do not want our network to ever see users or items that appear in the test set prior to test. We therefore use the following approach:

  1. get all unique reviewers
  2. extract the unique reviewers' data points to a test set
  3. place all remaining data points in a training set
  4. from the test set get a set of unique movies
  5. remove all entries with these movies from the training set

Following this procedure requires us to discard some data, but means that our testing set is entirely independent of the training set.
