Table 5.

Two agreement matrices relating the classifications performed by the pairs kNN and naïve Bayes models (KB) (Table 5a) and random forest and SGD models (FS) (Table 5b) on the Tic-Tac-Toe data set (DS4). The first rows/columns of these matrices count the correctly classified entries (C), while those misclassified (W) are packed in the second rows/columns

		Naïve Bayes				SGD

	W	120	157	Forest	W	39	10
(a) The agreement matrix relating the classifications performed by kNN and naïve Bayes models (KB). Its IA and κ are 0.11 and 0.36, respectively				(b) The agreement matrix relating the classifications performed by random forest and SGD models (FS). Its IA and κ are 0.25 and 0.29, respectively
