ECS-074-Pattern Recognition Assignment-1 1. What do you mean by learning and adaptation? Explain the components of a learning system. 2. Explain the concept of expectation maximization with the help of an algorithm. 3. Explain multivariate normal density using mathematical notations. 4. Explain Chi square test. How Chi-square test can be applied for testing null hypothesis? 5. A department store, A, has four competitors: B,C,D, and E. Store A hires a consultant to determine if the percentage of shoppers who prefer each of the five stores is the same. A survey of 1100 randomly selected shoppers is conducted, and the results about which one of the stores shoppers prefer are below. Is there enough evidence using a significance level a = 0.05 to conclude that the proportions are really the same? Store A B C D E Number of Shoppers 262 234 204 190 210
