The lack of transparency and clarity in AI decisionmaking poses challenges of ethics and trust. This article presents$K A N$, a class of networks developed by Ziming Liu among other researchers recently based on the Kolmogorov-Arnold representation theorem, designed to improve the performance and interpretability of classic$A I$algorithms. This article explains$K A N$in an understandable way, with examples and addresses the binary classification problem. The results show that$K A N$are competitive against other classification algorithms with the advantage that they are highly interpretable. Furthermore, in the datasets studied the$K A N$surpassed the MLP in the Friedman ranking. Moreover, it was found that its performance is similar, statistically speaking, to that of state-of-the-art classification algorithms. Therefore, KAN are a clear alternative when high performance and interpretability are required without the need to resort to post hoc tests.
