Q1) In the following neural network, the input has a value of 5 and its range is between 1 to 10, calculate the output x. Note that the transfer function for the nodes in the hidden layer is Hyperbolic Tangent, and for the output node is a Logistic function. Q2) Consider the following point-of-sales transactions (a) Generate the co-occurrence matrix for this transaction. (b) Generate 2 association rules. (c) Measure “support”, “confidence”, and “lift” for the rules you generated in part (b). Can you specify a useful (strong) rule? Q3) Consider the training data set shown in the following Table. We want to classify the new

Unformatted text preview: item <P20, F, 1.65> using K-Nearest Neighbor algorithm with K=4 and a simple majority voting. To calculate distances between each two records, we are required to consider both Gender and Height attributes . For the gender attribute, assume the following distance functions d(F, F) =d(M, M) = 0; d(F, M)=d(M, F)= 0.2 Using the Manhattan Distance, find the 4 nearest neighbors to the new item, and classify it based on a majority voting. In your solution, specify the neighbors, and calculate the distance between the new item and each neighbor. 1 2...
