The main one though is the fact that almost all neural nets are trained with different forms of stochastic gradient descent. This is why batch_size parameter exists which determines how many samples you want to use to make one update to the model …

WebParameters: size_average ( bool, optional) – Deprecated (see reduction ). By default, the losses are averaged over each loss element in the batch. Note that for some losses, there are multiple elements per sample. If the field size_average is set to False, the losses are instead summed for each minibatch. Ignored when reduce is False. sunova koers https://tfcconstruction.net
