A Physics-Inspired Optimizer: Velocity Regularized Adam
TL;DR
Optimization algorithms often struggle with convergence speed and stability in training machine learning models. Velocity Regularized Adam (VRA) was developed to enhance the Adam optimizer by incorporating a velocity term inspired by physics.
✦ Why It Matters
Engineers can use Velocity Regularized Adam to improve training efficiency and stability in their machine learning projects.
Key Takeaways
- Implement VRAdam to reduce oscillations during training.
- Utilize the velocity-based regularizer for improved convergence.
- Benchmark VRAdam against standard optimizers like AdamW.
- Explore VRAdam's application in diverse architectures and tasks.
How It Works
VRAdam incorporates a velocity regularization term that penalizes large weight updates, effectively slowing down the learning rate in high-velocity scenarios. This mechanism stabilizes the training process by damping oscillations, allowing for smoother convergence.
