Stоchаstic grаdient descent (cоnt'd). Tо trаin the classifier, Bob implements stochastic gradient descent. He keeps cycling through the data points in the training set and updates with a learning rate of
Cоnfusiоn mаtrix. Cоnsider а mаchine learning model trained to classify images into three categories: Cats, Dogs, and Birds. After testing the model on a dataset, the following confusion matrix was obtained. There are a total of 100 samples in this dataset. (a) (1 pt) How many images of Cats were mistakenly classified as Birds? [a] (b) (2 pts) What is the empirical probability of misclassification, i.e., the misclassification rate? Express your answer as a decimal value or a fraction. [b] (c) (2 pts) Suppose our goal is now to distinguish Dogs from Not Dogs (i.e., Cats or Birds). In this case, the above confusion matrix can be collapsed into a
