- Título: Online Machine Learning for Imbalanced Multi-Label Streams
- Ponente: José Enrique Ruiz Navarro
- Resumen: This talk introduces online machine learning for severely imbalanced multi-label streams and examines loss-function adaptation. Fixed baselines (BCE, weighted cross-entropy, static focal) are compared with adaptive strategies: greedy updates, momentum-anchored robust control, and learnable loss parameters. Methods are evaluated prequentially with windowed Macro-F1, Micro-F1, Hamming loss, and Exact Match, highlighting stability and metric-alignment trade-offs.
