# PIQ Posthoc Interpreter trained on ESC50

This repository provides all the necessary tools to perform audio posthoc interpretations using the [PIQ](https://arxiv.org/abs/2303.12659) method on a conv-2d classifier, with the following performance on the ESC50 dataset: 


| Release | Classification Accuracy Valid | Classification Accuracy Test | 
|:-------------:|:--------------:|:--------------:|
| 15-07-23 | 80% | 75% |


Please, take a look at the [reference paper](https://arxiv.org/abs/2303.12659) for more info. You can find the training recipe in SpeechBrain [here](https://github.com/speechbrain/speechbrain/tree/develop/recipes/ESC50/interpret).




## Install SpeechBrain

First of all, please install SpeechBrain with the following command:

```
pip install speechbrain
```

Please notice that we encourage you to read our tutorials and learn more about

### Perform Interpretable Classification on your own file

```python
from speechbrain.inference.interpretability import PIQAudioInterpreter
import torchaudio

model = PIQAudioInterpreter.from_hparams(source="speechbrain/PIQ-ESC50", savedir='pretrained_models/PIQ-ESC50')
x_int_sound_domain, text_lab, fs_model = model.interpret_file('speechbrain/PIQ-ESC50/mix.wav')

print('Classification is {}'.format(text_lab))
torchaudio.save("interpretation.wav", x_int_sound_domain.data.cpu(), fs_model)
```


### Limitations
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
