 This folder contains [`run_audio_classification.py`](https://github.com/huggingface/optimum/blob/main/examples/openvino/audio-classification/run_audio_classification.py), a script to fine-tune a 🤗 Transformers model on the 🗣️ [Keyword Spotting subset](https://huggingface.co/datasets/superb#ks) of the SUPERB dataset while applying Quantization-Aware Training (QAT). QAT can be easily applied by replacing the Transformers [`Trainer`](https://huggingface.co/docs/transformers/main/en/main_classes/trainer#trainer) with the Optimum [`OVTrainer`]. Any model from our [hub](https://huggingface.co/models) can be fine-tuned and quantized, as long as the model is supported by the [`AutoModelForAudioClassification`](https://huggingface.co/docs/transformers/main/en/model_doc/auto#transformers.AutoModelForAudioClassification) API.

 The following command shows how to fine-tune [Wav2Vec2-base](https://huggingface.co/facebook/wav2vec2-base) on the 🗣️ [Keyword Spotting subset](https://huggingface.co/datasets/superb#ks) of the SUPERB dataset with Quantization-Aware Training (QAT). The `OVTrainer` uses a default quantization configuration which should work in many cases, but we can also customize the algorithm details. Here, we quantize the Wav2Vec2-base model with a custom configuration file specified by `--nncf_compression_config`. For more details on the quantization configuration, see NNCF documentation [here](https://github.com/openvinotoolkit/nncf/blob/develop/docs/compression_algorithms/Quantization.md).

 ### Joint Pruning, Quantization and Distillation (JPQD) for BERT on SQuAD1.0
-`OVTrainer` also provides an advanced optimization workflow through the NNCF when Transformer model can be structurally pruned along with 8-bit quantization and distillation. Below is an example which demonstrates how to jointly prune, quantize BERT-base for SQuAD 1.0 using NNCF config `--nncf_compression_config` and distill from BERT-large teacher. This example closely resembles the movement sparsification work of [Lagunas et al., 2021, Block Pruning For Faster Transformers](https://arxiv.org/pdf/2109.04838.pdf). This example takes about 12 hours with a single V100 GPU and ~40% of the weights of the Transformer blocks were pruned.
