Abstract

Current brain-machine interfaces (BMIs) often rely on decoders trained for single tasks, limiting their flexibility in real-world applications. We propose an online learning framework that enables the transfer of neural-to-movement (knowledge) across tasks, supporting both task switching and memory retention. In our framework, neural activity is projected into a dynamical jPCA space to effectively dissociate into variant and invariant components. The variant components of the neural patterns are then aligned by deriving Gradient-based Kullback–Leibler Divergence Minimization (GKLD) for efficient online adaptation. A kernel reinforcement learning (KRL) model then decodes aligned neural signals while reusing prior neural-to-movement mapping. Evaluated on rats switching between a one-lever pressing and a two-lever discrimination task, the framework shows rapid convergence, over four times faster than the baseline method, and improves decoding accuracy by around 35% during task switching. Furthermore, when switching back to the original task, the framework successfully retains knowledge from the old task. Our method demonstrates general applicability to multiple task switching scenarios and maintains stable decoding across three representative days over a 21-day period, highlighting its potential for long-term, real-world use.
脑机接口中任务切换和保持的在线神经到运动映射转移。
目前的脑机接口(bmi)通常依赖于为单一任务训练的解码器,限制了它们在现实应用中的灵活性。我们提出了一个在线学习框架,使神经到运动(知识)的跨任务转移,支持任务切换和记忆保留。在我们的框架中,神经活动被投射到一个动态的jPCA空间中,以有效地分离为变分量和不变分量。然后,通过推导基于梯度的Kullback-Leibler散度最小化(GKLD)来对齐神经模式的变体组件,以实现有效的在线自适应。然后,核强化学习(KRL)模型在重用先前的神经到运动映射的同时解码对齐的神经信号。在大鼠单杆按压和双杆辨别任务切换中,该框架显示出快速收敛,比基线方法快4倍以上,并在任务切换期间提高了约35%的解码精度。此外,当切换回原始任务时,该框架成功地保留了旧任务中的知识。我们的方法证明了对多任务切换场景的普遍适用性,并在21天的时间内保持了三天的稳定解码,突出了其长期实际使用的潜力。
