Expectation Maximization in Collaborative Filtering Jonathan Baker 2010 Abstract Expectation maximization (EM) is a method of approximating maximum likelihood estimators (MLE) in models with missing data or latent variables. A straightforward application of EM is collaborative filtering (CF): using data from multiple agents to predict unreported values. In this paper, we show a simple method of applying EM to a large CF problem: predicting ratings in the Netflix Prize dataset. 1 Auxiliary

ANALYSIS OF REGRESSION Jessica Cain American InterContinental University Abstract The world today uses statistics in many different ways to understand numbers and possible outcomes. One way that this is by using regression analysis. The regression analysis which is based on a correlation between two variables can help us to better understand the relationship between the two variables. The process which is a valuable one has helped researchers, and businesses to grow based on information
