a. Consider the following table showing results of a binary classification problem with validation data. Actual Class Predicted Class 0 1 0 1 1 0 1 1 1 0 0 1 1 0 1 0 Build the confusion matrix. Compute Classifier accuracy, Precision, Recall, and F-score for class 1 based on the above data. (1+1+.5+.5+1 marks) b.
