Machine learning commonly used variable names

the BatchSize : Chinese translated as batch size (batch size). Depth study, the general SGD training, i.e. each training in the training set of training samples taken batchsize;
iteration : Chinese translation of iterations, one iteration of training samples is equal to one used batchsize; a forward iteration through a = a + by reverse
epoch : the number of iterations, a training epoch is equal to the total sample time using the training set; a = epoch all the training samples of a forward pass and a reverse pass
