In machine learning, after collecting, cleaning data, and designing preprocessing algorithms, how do we know the effectiveness of the algorithm? How to evaluate if the predictive model can classify effectively and how accurate the classification is? This involves the confusion matrix, which is widely used to evaluate classification problems in machine learning.……
