研究非马尔可夫环境下随机逼近的新框架,解析Transformer与持续学习的理论基础。

Stochastic approximation in non-markovian environments revisited

  • 构建非遍历非马尔可夫过程下的随机逼近分析框架
  • 揭示注意力机制与持续学习依赖完整历史的内在机理
  • 为自回归模型和长时依赖学习提供理论支撑

基于作者近期关于非马尔可夫环境中随机逼近的研究,本文进一步探讨了驱动随机过程既非马尔可夫又非遍历的情况。在此基础上,提出一个分析框架,用于理解基于Transformer的学习机制,特别是注意力机制,以及持续学习。这两类方法在原则上都依赖于完整的过去信息。该框架为分析具有长期依赖性的序列建模提供了新的理论视角。

原文摘要 · Abstract (English)

Based on some recent work of the author on stochastic approximation in non-markovian environments, the situation when the driving random process is non-ergodic in addition to being non-markovian is considered. Using this, we propose an analytic framework for understanding transformer based learning, specifically, the `attention' mechanism, and continual learning, both of which depend on the entire past in principle.
