Methods

(network)itertrain
(train[, valid])Train a model using a training and validation set. reservoir
(xs, n, rng)Select a random sample of n items from xs. -
itertrain
(train, valid=None, **kwargs)¶ Train a model using a training and validation set.
This method yields a series of monitor values to the caller. After every iteration, a pair of monitor dictionaries is generated: one evaluated on the training dataset, and another evaluated on the validation dataset. The validation monitors might not be updated during every training iteration; in this case, the most recent validation monitors will be yielded along with the training monitors.
Parameters: train :
Dataset
A set of training data for computing updates to model parameters.
valid :
Dataset
A set of validation data for computing monitor values and determining when the loss has stopped improving.
