Computes the mean absolute error between predictions and targets.

Usage

mlx_l1_loss(predictions, targets, reduction = c("mean", "sum", "none"))

Arguments

predictions

Predicted values as an mlx array.

targets

Target values as an mlx array.

reduction

Type of reduction: "mean" (default), "sum", or "none".

Value

An mlx array containing the loss.
