# Model Card for Model ID

<!-- Provide a quick summary of what the model is/does. -->

This modelcard aims to be a base template for new models. It has been generated using [this raw template](https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/templates/modelcard_template.md?plain=1).

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->

```python
class WhisperCTC(nn.Module):
    def __init__(
        self,
        encoder_id: str = "tuanio/whisper-encoder.tiny.en",
        dropout: float = 0.1,
        vocab_size: int = 47,
    ):
        super().__init__()
        self.encoder = WhisperEncoder.from_pretrained(encoder_id)
        print("Freezing Whisper Encoder...")
        self.encoder._freeze_parameters()
        print("Freezed!")
        self.lm_head = nn.Sequential(
            nn.SiLU(),
            nn.Dropout(dropout),
            nn.Linear(self.encoder.config.d_model, vocab_size),
        )
        nn.init.kaiming_uniform_(
            self.lm_head[-1].weight, mode="fan_in", nonlinearity="relu"
        )

    def forward(self, feat: Tensor, attn_mask: Tensor):
        enc = self.encoder(
            input_features=feat, attention_mask=attn_mask
        ).last_hidden_state
        logits = self.lm_head(enc)
        log_probs = nn.functional.log_softmax(logits, dim=-1)
        return log_probs
