Exponential decay is the decrease in a quantity N according to the law N ( t ) = N 0 e − λ t , ( 1 ) N(t)=N_{0}e^{-\lambda t} , (1) N(t)=N0e−λt,(1) for a parameter t and constant lambda (known as th
params_decay = (p for name, p in self.named_parameters() if 'bias' not in name)params_no_decay = (p for name, p in self.named_parameters() if 'bias' in name) 这段代码是在PyTorch中对模型的参数进行筛选,以便在优化器中为不同的参数组
