Top k categorical accuracy

具体计算方法为：1）根据y_pred中的每个样本预测的分数得到y_pred_new= [1, 1, 1, 0]；2）将y_true和y_pred_new代入到2.1中计算得到最终的categorical_accuracy=75%。 5) top_k_categorical_accuracy 在categorical_accuracy的基础上加上top_k。 categorical_accuracy要求样本在真值类别上的预测分数是在所有类别上预测分数的最大值，才算预测对，而top_k_categorical_accuracy只要求样本在真值类别上的预测分数排在其在所有类别上的预测分数的前k名就行。The educational system called K-12 education refers to the combination of primary and secondary education that children receive from kindergarten until 12th grade, typically starting at ages 4-6 and continuing through ages 17-19.K-Nearest Neighbors If you’re familiar with machine learning or have been a part of Data Science or AI team, then you’ve probably heard of the k-Nearest Neighbors algorithm, or simple called as KNN.
