📰 Dev.to · Alan West

Learn to debug silently failing neural networks with practical strategies from data pipeline checks to gradient monitoring

intermediate Published 26 Apr 2026
Action Steps
  1. Check data pipelines for inconsistencies using tools like TensorFlow Data Validation
  2. Monitor gradients to detect vanishing or exploding gradients using TensorBoard
  3. Detect distribution shifts in training and testing data using statistical methods like KS-statistic
  4. Apply regularization techniques to prevent overfitting
  5. Visualize model performance on a validation set to identify silent failures
