BinaryCrossentropy

Description

Computes the crossentropy metric between the labels and predictions. Type : polymorphic.

Input parameters

 y_pred : array, predicted values (if from_logits = true then y_pred is logits data else is probabilities between 0 and 1).
 y_true : array, true values (binary numerical label [ 0 ], [ 1 ]).
from_logits : boolean, whether output is expected to be a logits tensor.

Output parameters

binary_crossentropy : float, result.

Use cases

The binary crossentropy metric is a loss function used in machine learning, particularly in binary classification problems. Cross entropy measures the performance of a classification model whose outputs are probabilities between 0 and 1.

It is commonly used in many fields, including :

• • Recommendation systems : to predict whether a user will like a product or not.
  • Fraud detection : to predict whether a transaction is fraudulent or not.
  • Medicine : to predict whether a patient has a disease or not.

Calculation

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