Suppose you want to use Naive Bayes to perform document classification (binary clas- sification) using the bag of words model where we have D documents and a total of n words. How many probabilities would a Naive Bayes classifier need to learn? Suppose, your boss says, change the order of sentences in each document and re-learn the Naive Bayes classifier, do you expect the learned model to be different? Briefly explain

1. If you stored the following binary number (-0.000000100101) as a binary floating point number, what value would be STORED in the exponent section? Also convert A7.11 Hex value to floating point. 2. Number of bits saved using Huffman encoding. From the following characters used in a message with their associated frequency, use Huffman Coding as a compression technique. How many bits will be saved in the message? (Keep in mind that one character is one byte which consists of...

5. You have been given the task of determining if the number of board feet of lumber (Volume) from a black cherry tree can be predicted from the diameter of the tree at 54 inches from the ground. You have data from 31 black cherry trees in New Zealand about their volume, height, and diameter. You need to analyze the data and write a couple of sentences discussing the questions below. Follow the steps we use in class to analyze...

You have been assigned the task of using the corporate, or free cash flow model to estimate KCB Corporation's intrinsic value. The firm's WACC is 10.00%, its end-of-year free cash flow (FCF1) is expected to be $75.0 million, the FCFs are expected to grow at a constant rate of 5.00% a year in the future, the company has $200 million of long-term debt and preferred stock, and it has 30 million shares of common stock outstanding. Why should the WACC...

USING 3 FILES breast-cancer.arff, diabetes.arff and iris.arff IN WEKA 3.8 Task 1: Classification performance evaluation [10 marks] In this comparative analysis task, you are required to evaluate classification performance of five algorithms on three datasets using Weka. Load breast-cancer.arff, diabetes.arff and iris.arff datasets into Weka one at a time and run each of the below algorithms with their default settings. Then, collect a 10-fold cross-validation classification results for quantitative evaluation. a. MultilayerPerceptron b. Naive Bayes c. J48 d. RandomForest e. RERTree...
