Local structures are powerful enough to make our MRF work, but they model At test time, we will introduce unseen items into the model assuming that the model won't change. For simplicity, assume that latent factors are binary. The course is coming to the Washington DC area 20-22 Feb 2012. One of the most common types of recommendation engine, Collaborative Filtering is a behavior based system that functions solely on the assumption that people with similar interests share common preferences. The purpose of this post is to explain how to use Apache Mahout to deploy a massively scalable, high throughput recommender system for a certain class of usecases. Until recently, this literature suggests, research on recommendation systems has focused almost exclusively on accuracy, which led to systems that were likely to recommend only popular items, and hence suffered from a "popularity bias'' (Celma and Herrera 2008). Techniques for delivering recommendations. In the previous post we talked about how Markov random fields (MRFs) can be used to model local structure in the recommendation data. For our purposes we can broadly group most techniques into three primary types of recommendation engines: Collaborative Filtering, Content-Based and Data Mining. Online Controlled Experiments: Introduction, Learnings, and Humbling Statistics. ACM Recommender System 2012: Most discussed and tweeted papers and presentations #RecSys2012. We will briefly introduce each below. Cloudera University is offering a new training course on data science titled Introduction to Data Science – Building Recommender Systems. The authors then introduced a number of "item re-ranking methods that can generate substantially more diverse recommendations across all users while maintaining comparable levels of recommendation accuracy. Markov random fields for recommender systems II: Discovering latent space.
