BinaryCrossentropy

public class BinaryCrossentropy

A Metric that computes the binary cross-entropy loss between true labels and predicted labels.

This is the crossentropy metric class to be used when there are only two label classes (0 and 1).

BinaryCrossentropy(Ops tf, String name, boolean fromLogits, float labelSmoothing, long seed, Class<T> type)

Creates a BinaryCrossentropy metric

Operand<T>

call(Operand<? extends TNumber> labels, Operand<? extends TNumber> predictions)

Calculates the weighted loss between labels and predictions

LossMetric<T>	getLoss() Gets the loss function.
List<Op>	updateStateList(Operand<? extends TNumber> labels, Operand<? extends TNumber> predictions, Operand<? extends TNumber> sampleWeights) Creates Operations that update the state of the mean metric, by calling the loss function and passing the loss to the Mean metric to calculate the weighted mean of the loss over many iterations.

Variable<T>	getCount() Gets the count variable
Class<T>	getResultType() Gets the type for the variables
Variable<T>	getTotal() Gets the total variable
Op	resetStates() Resets any state variables to their initial values
Operand<T>	result() Gets the current result of the metric
List<Op>	updateStateList(Operand<? extends TNumber> values, Operand<? extends TNumber> sampleWeights) Updates the metric variables based on the inputs.

final Operand<T>	callOnce(Operand<? extends TNumber> values, Operand<? extends TNumber> sampleWeights) Calls update state once, followed by a call to get the result

Public Constructors

Creates a BinaryCrossentropy metric

tf	the TensorFlow Ops
name	the name of this metric, if null then metric name is `getSimpleName()`.
fromLogits	Whether to interpret predictions as a tensor of logit values as opposed to a probability distribution.
labelSmoothing	value used to smooth labels, When 0, no smoothing occurs. When > 0, compute the loss between the predicted labels and a smoothed version of the true labels, where the smoothing squeezes the labels towards 0.5. Larger values of label_smoothing correspond to heavier smoothing.
seed	the seed for random number generation. An initializer created with a given seed will always produce the same random tensor for a given shape and data type.
type	the type for the variables and result

Calculates the weighted loss between labels and predictions

labels	the truth values or labels
predictions	the predictions
