WebJul 17, 2024 · numpy.bincount. numpy.bincount(x, weights=None, minlength=0) 统计每个元素的出现次数。 bin值为x中最大数字的值+1，函数返回一个长度为bin的array，表示每个数字的出现次数。参数： x：一维非负整数array; weights：一个与x具有相同shape的array，可以为不同位置设定不同的统计权重 Web首先将output和target作为参数，输入到update函数中，这个时候输入进来的a和b已经是每个概率对应到类别了（可参考第二节的argmax（）函数）。 Output作为预测的类别，target作为真实的类别，两组参数形成一个混淆矩阵，计算各项指标。
