Programming Assignment 7: Fraud Detection /* ***************************************************************************** * Describe how you implemented the Clustering constructor **************************************************************************** */ /* ***************************************************************************** * Describe how you implemented the WeakLearner constructor **************************************************************************** */ /* ***************************************************************************** * Consider the large_training.txt and large_test.txt datasets. * Run the boosting algorithm with different values of k and T (iterations), * and calculate the test data set accuracy and plot them below. * * (Note: if you implemented the constructor of WeakLearner in O(kn^2) time * you should use the training.txt and test.txt datasets instead, otherwise * this will take too long) **************************************************************************** */ k T test accuracy time (seconds) -------------------------------------------------------------------------- /* ***************************************************************************** * Find the values of k and T that maximize the test data set accuracy, * while running under 10 second. Write them down (as well as the accuracy) * and explain: * 1. Your strategy to find the optimal k, T. * 2. Why a small value of T leads to low test accuracy. * 3. Why a k that is too small or too big leads to low test accuracy. **************************************************************************** */ /* ***************************************************************************** * Known bugs / limitations. **************************************************************************** */ /* ***************************************************************************** * Describe any serious problems you encountered. **************************************************************************** */ /* ***************************************************************************** * List any other comments here.
