LogCosh

Description

Computes the logarithm of the hyperbolic cosine of the prediction error.​ Type : polymorphic.

Input parameters

LogCosh in : class
reduction : enum, type of reduction to apply to the loss. In almost all cases this should be “Sum over Batch“.

Output parameters

LogCosh out : class

Required data

 y_pred : array, predicted values.
 y_true : array, true values.

Use cases

LogCosh loss, or logarithmic hyperbolic cosine loss, is a loss function used in regression tasks. It is designed as an alternative to mean squared error (MSE) and mean absolute error (MAE), offering an approach that combines reduced sensitivity to outliers, like MAE, with the smoothness and differentiability of MSE.

This loss function is particularly effective when data shows variability but without extreme outliers, making it useful in scenarios where robustness is key without sacrificing gradient accuracy.
