luz_callback_metrics: Metrics callback

In luz: Higher Level 'API' for 'torch'

Metrics callback

Description

Tracks metrics passed to setup() during training and validation.

Usage

luz_callback_metrics()

Details

This callback takes care of 2 ctx attributes:

• ctx$metrics: stores the current metrics objects that are initialized once for epoch, and are further update()d and compute()d every batch. You will rarely need to work with these metrics.

• ctx$records$metrics: Stores metrics per training/validation and epoch. The structure is very similar to ctx$losses.

Value

A luz_callback

Note

In general you won't need to explicitly use the metrics callback as it's used by default in fit.luz_module_generator().
