Extra Credit: Which of the following are the indicators of overfitting in a model? (There can be more than two answers)

(j)  K-Means is ideal for detecting arbitrarily shaped clusters.

Extra Credit: If overfitting is observed in a model, which of the following changes would be most beneficial? (There can be more than two answers)

Does this curve indicate overfitting? If so, where does overfitting occur? Select one of the options below.

(c) The KNN algorithm relies on feature scaling (e.g., normalization) to work effectively when using Euclidean distance as a metric.

(i)  Support Vector Machine can handle high dimensional data. 

(b) Based on this training data set, assume you would like to predict a user’s rating of an unrated movie, i.e., classify the user into 5 categories (rating 1 to 5), given the user’s rating to other similar movies rated by the same user. Between “KNN”, “Neural network”, and “Naïve Bayes”, which one would you use and why? (Please limit your answer to 30 words).

(b) Increasing the value of “K” in KNN generally makes the model more sensitive to outliers.

Quizzes are located in the learning modules. Questions will be objective and associated with the content material for the cited text chapters. There are both True/False and Multiple Choice type questions Each quiz is comprised of 50 questions from which 20 questions will be randomly selected. Each question is valued at .5 (half a point) resulting in a total possible score of 10 points per quiz. Procedures for the online test format, Honorlock, are available in the attached file. Review the information to prepare for taking the quiz. Unit 2 has 2 Quizzes that are 45 minutes each. About Honorlock.pdf Honorlock – Selected Standard Guidelines for this Course.pdf
