# VisualEars FastConformer FA Full AB - QAT W2 Materialized

This repo contains the current 2-bit QAT materialized NeMo checkpoint from the VisualEars FastConformer Persian ASR quantization experiments.

Important: this is a **materialized float NeMo checkpoint**, not a packed 2-bit deployment artifact yet. The selected QAT linear weights are projected to their 2-bit values and saved back into normal NeMo/torch tensors, so the file size is still close to the full precision `.nemo`.

## Source

Base model: `Reza2kn/visualears-fastconformer-fa-full-ab`

Training run: `onebit_cotraining_fast_no_urls_lower3_20260612_161154`

Quantized modules: feed-forward linear layers in encoder layers 0-2, decoder/CTC/attention/convolution left unquantized.

## VisualEars269 score

Default decoding:

| model | WER | CER |
|---|---:|---:|
| FP baseline | 32.64% | 13.30% |
| W2 materialized | 37.47% | 16.69% |

Forced CTC:

| model | WER | CER |
|---|---:|---:|
| FP baseline | 34.96% | 14.36% |
| W2 materialized | 40.65% | 17.78% |

This is useful as an experimental checkpoint, but it is not yet parity and not yet compressed/bit-packed.
