CATFormer: When Continual Learning Meets Spiking Transformers With Dynamic Thresholds

arXiv – CS AI|Vaishnavi Nagabhushana, Kartikay Agrawal, Ayon Borthakur|
🤖AI Summary

Researchers introduce CATFormer, a new spiking neural network architecture that solves catastrophic forgetting in continual learning through dynamic threshold neurons. The framework uses context-adaptive thresholds and task-agnostic inference to maintain knowledge across multiple learning tasks without performance degradation.

Key Takeaways
  • CATFormer introduces Dynamic Threshold Leaky Integrate-and-Fire neurons that prevent catastrophic forgetting in spiking neural networks
  • The framework uses context-adaptive thresholds as the primary mechanism for knowledge retention across multiple learning tasks
  • Gated Dynamic Head Selection mechanism enables task-agnostic inference without knowing which task is being performed
  • Testing on CIFAR-10/100, Tiny-ImageNet, and neuromorphic datasets shows superior performance over existing rehearsal-free algorithms
  • The architecture enables energy-efficient continual learning that mimics brain-like learning without forgetting
