Currently if I write a function like the following: ```py def mask_invalid( x: Shaped[Array, '*B *C'], mask: Bool[Array, '*B'] ) -> Shaped[Array, '*B *C']: return jnp.where(jnp.expand_dims(mask, range(mask.ndim, x.ndim)), x, 0)...

Techniques for reducing memory usage for large lattices such as GNAT

Hi k2 developers! I am trying to implement a rudimentary version [GNAT](https://arxiv.org/abs/2205.13674) in k2, largely following [the CTC implementation in Icefall](https://github.com/k2-fsa/icefall/blob/cad6735e0739f149ba3f452e52a948da946527dc/egs/librispeech/ASR/conformer_ctc/train.py#L398): 1. A sausage with actual scores is created using...

Currently both functions call ScoreCCandidate in SentenceScorer to get a ScoreP smart pointer (which, when non-null, gives access to non-static versions of Score::GetZero or Score::GetOne). However, most actual implementations of...
