Descripción de la fuente
This model is a fine-tuned version of facebook/wav2vec2-base for multi-label emotion classification from audio.
The model uses a Hydra architecture with multiple binary classification heads, one for each emotion. It supports ignore labels (-100) for handling uncertain or unlabeled data points.

This model was trained with support for ignore labels (-100). During inference:
import torch
from transformers import Wav2Vec2Processor
# Load model and processor
model = # Load your model here
processor = Wav2Vec2Processor.from_pretrained('mangoesai/wav2vec2-emotion-classifier-V2')
# Process audio
inputs = processor(audio_array, sampling_rate=16000, return_tensors="pt", padding=True)
# Get predictions
with torch.no_grad():
outputs = model(inputs.input_values, inputs.attention_mask)
probabilities = torch.sigmoid(outputs)
predictions = (probabilities > 0.5).int()
