Kernel Adaptive Memory: testing persistent kernel memory for sequence models

Six phases of preregistered experiments asking whether a kernel-routed persistent memory helps sequence models: no general advantage yet, but the hypothesis has narrowed from dense radial attention to sparse, top-K-routed separable memory.

Latent-signal classification with hierarchical dynamical systems

Pipeline that maps noisy multichannel time-series observations to compact latent trajectories with a Hierarchical Linear Dynamical System (HLDS), then evaluates those trajectories for classification, separability, and stability.

Zebrafish neural imaging: event detection & source separation

Research platform for zebrafish neural-imaging video: statistical event detection for voltage recordings and a calcium-imaging experiment program that separates activity from background, artifacts, and noise.

Spike-train decoding with kernel least-mean-squares (KLMS)

A faithful Python reproduction of Li et al. (IEEE MLSP 2011): a spike-time RKHS KLMS decoder that maps spike trains to micro-stimulation, benchmarked against binned KLMS and GLM baselines.
