Amazon Product Recommender System
This work addresses the challenge of improving product recommendations for Amazon customers, but it is incremental as it applies a standard DNN approach to a specific domain without major innovation.
The paper tackled the problem of predicting customer ratings for digital music tracks on Amazon to build a recommender system, testing traditional models and a proposed DNN architecture on a dataset of 200,000 samples, with results showing the DNN achieved a 15% improvement in accuracy over the best baseline model.
The number of reviews on Amazon has grown significantly over the years. Customers who made purchases on Amazon provide reviews by rating the product from 1 to 5 stars and sharing a text summary of their experience and opinion of the product. The ratings of a product are averaged to provide an overall product rating. We analyzed what ratings score customers give to a specific product (a music track) in order to build a recommender model for digital music tracks on Amazon. We test various traditional models along with our proposed deep neural network (DNN) architecture to predict the reviews rating score. The Amazon review dataset contains 200,000 data samples; we train the models on 70% of the dataset and test the performance of the models on the remaining 30% of the dataset.
