spamosaic.loss.CL_loss

class spamosaic.loss.CL_loss(*args: Any, **kwargs: Any)

Contrastive Loss for multi-view representation alignment.

This loss function is designed to encourage representations from the same sample across multiple modalities to be similar, while pushing apart representations from different samples.

Parameters:

• batch_size (int) – Number of samples in a mini-batch (per modality).

• rep (int, optional) – Number of modalities or views (default: 3).

• bias (float, optional) – Small constant added to negative sample logits to avoid instability in log computations (default: 0).
