Multi-View Broad Learning System for Primate Oculomotor Decision Decoding
This work addresses brain state decoding for neuroscience research, but it is incremental as it adapts an existing method to a specific application.
The paper tackled the problem of decoding primate oculomotor decisions from neural signals by extending the broad learning system (BLS) to multi-view learning using local field potentials (LFPs) and spikes as complementary views, and demonstrated that this approach is more effective than classical and state-of-the-art methods.
Multi-view learning improves the learning performance by utilizing multi-view data: data collected from multiple sources, or feature sets extracted from the same data source. This approach is suitable for primate brain state decoding using cortical neural signals. This is because the complementary components of simultaneously recorded neural signals, local field potentials (LFPs) and action potentials (spikes), can be treated as two views. In this paper, we extended broad learning system (BLS), a recently proposed wide neural network architecture, from single-view learning to multi-view learning, and validated its performance in decoding monkeys' oculomotor decision from medial frontal LFPs and spikes. We demonstrated that medial frontal LFPs and spikes in non-human primate do contain complementary information about the oculomotor decision, and that the proposed multi-view BLS is a more effective approach for decoding the oculomotor decision than several classical and state-of-the-art single-view and multi-view learning approaches.
