A confusion matrix is a table that is often used to describe the performance of a classification model (or "classifier") on a set of test data for which the true values are known. Two cells are said to be connected if they are adjacent to each other horizontally, vertically, or diagonally. In mathematics, a binary operation or dyadic operation is a calculation that combines two elements (called operands) to produce another element. Given a binary matrix of order m*n, the task is to find the distance of nearest 1 for each 0 in the matrix and print final distance matrix. Another way to use this classifier is to select the best scenario from a set of single-label classifiers used with Binary Relevance, this can be done using cross validation grid search.
