predicts是什么意思dicts在线翻译读音例

dice，准确率（Accuracy）、精确率（Precision）、召回率（Recall）。。。

具体的原理就不讲解了，直接上代码

label和predict都是one-hot型

defcompute_PCC(predicts,label):

assert(==)

PC天寒地冻造句 C=[]

foriinrange([1]):

n=[0]*[2]*[3]

TP=((predi中秋祝福经典短句 cts[:,i,:,:]==1)*(label[:,i,:,:]==1)).sum()

sum_x=predicts[:,i,:,:].sum()

sum_y=label[:,i,:,:].sum()

sum_x2=predicts[:,i,:,:].pow(2).sum()

sum_y2=label[:,袁枚最有名的十首诗 i,:,:].二年级上册语文书内容 pow(2).sum()

molecular=TP-(float(sum_x)*float(sum_y)/n)

denominator=((sum_x2-float(sum_x2**2)/n)*(sum_y2-float(sum_y2**2)/n)).sqrt()

(molecular/denominator)
