Project Overview • Improve the Amazon Retail Experience • Automatically Classify Reviews into Categories • Enable More Informed Purchasinng Decisions • Filter Out Non-Product Reviews The Capstone Experience Team Amazon Beta Presentation 2
Data • Amazon Review APIs are closed • Historical Data from USCD study • Team hand classified 4000 reviews for training The Capstone Experience Team Amazon Beta Presentation 3
Machine Learning • Amazon Machine Learning uses Logistic Regression • Loss function optimized with stochastic gradient descent • Minimizing “chance” that a review is misclassified The Capstone Experience Team Amazon Beta Presentation 4
