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

Case of Salary discrimination based on Gender In this case the assertion has been made that the males of the population receive a higher salary than do females as a direct result of their gender. In order to test this assertion, we must first set up a hypothesis, and then test that hypothesis by analyzing the data provided. The first step in hypothesis testing is formalizing the hypothesis into a null hypothesis and an alternative hypothesis. The null hypothesis is a restatement of the assertion
