he training set has 3 unique label values (A, B, C). Assume that you have 3 trained binary classifiers (M1, M2, M3) using logistic regression. M1 classifies an input to A or B; M2 classifies an input to B or C and M3 classifies an input to A or C. How can you combine the 3 classifiers to one multinomial classifier to classify an input to A, B or C?

3. Suppose for a binary classification problem that you have a data set of 50 examples, evenly split between positive and negative examples. If leave-one-out cross-validation is used, how will a simple majority classifier perform? Such a classifier outputs the class that is in the majority in the training set, regardless of the input. Please explain.

Do it on (c) pls..... 1. Assume you have an input file with 6 integer values. Scan these values into an appropriate array. 2. Create a user defined function that takes your array as an input and order your array from lowest to highest. Ex. If you have an array called num, then num[0] should contain the smallest value while num[5] will contain the largest value. 3. Output the values between 50-75 into an output file called “results.txt” 4. Any...
