Configure a Keras model for training

compile(object, optimizer, loss, metrics = NULL, loss_weights = NULL,
  sample_weight_mode = NULL, ...)

Arguments

object

Model object to compile.

optimizer

Name of optimizer or optimizer object.

loss

Name of objective function or objective function. If the model has multiple outputs, you can use a different loss on each output by passing a dictionary or a list of objectives. The loss value that will be minimized by the model will then be the sum of all individual losses.

metrics

List of metrics to be evaluated by the model during training and testing. Typically you will use metrics='accuracy'. To specify different metrics for different outputs of a multi-output model, you could also pass a named list such as metrics=list(output_a = 'accuracy').

loss_weights

Optional list specifying scalar coefficients to weight the loss contributions of different model outputs. The loss value that will be minimized by the model will then be the weighted sum of all indvidual losses, weighted by the loss_weights coefficients.

sample_weight_mode

If you need to do timestep-wise sample weighting (2D weights), set this to "temporal". NULL defaults to sample-wise weights (1D). If the model has multiple outputs, you can use a different sample_weight_mode on each output by passing a list of modes.

Additional named arguments passed to tf$Session$run.
