DBS-Adam Optimiser Improves Accident Severity Prediction

other · 2026-05-16

A new deep learning optimiser, Dynamic Batch-Sensitive Adam (DBS-Adam), dynamically scales learning rates based on batch difficulty, improving training stability and convergence speed. It is evaluated on Bi-Directional LSTM networks for vehicular accident injury severity prediction, addressing class imbalance with SMOTE-ENN and Focal Loss.

Key facts

  • DBS-Adam uses a batch difficulty score from exponential moving averages of gradient norms and batch loss.
  • It increases updates for difficult batches and reduces them for easier ones.
  • Integrated with Bi-Directional LSTM networks for accident injury severity prediction.
  • Class imbalance handled via SMOTE-ENN resampling and Focal Loss.
  • Four experimental configurations compare baseline Bi-LSTM models and alternative architectures.
  • Published on arXiv with ID 2605.15083.
  • The optimiser is designed for imbalanced and sequential datasets.
  • Aims to improve model efficiency and convergence speed.
