Losses & Metrics¶
Permutation invariant training (PIT) made easy¶
Asteroid supports regular Permutation Invariant Training (PIT), it’s extension using Sinkhorn algorithm (SinkPIT) as well as Mixture Invariant Training (MixIT).

Available loss functions¶
PITLossWrapper
supports three types of loss function. For “easy” losses,
we implement the three types (pairwise point, single-source loss and multi-source loss).
For others, we only implement the single-source loss which can be aggregated
into both PIT and nonPIT training.
