PPMI-Gated BCM Sparse Graph Encoder

Replace a dense graph embedding table or end-to-end GNN encoder with a fixed-width binary SDR learned from streaming random-walk context pairs. Use PPMI to amplify informative node-context pairs and a local BCM update to learn detector columns, followed by k-winner-take-all binarization. The resulting sparse code can be used directly for node classification, link prediction, retrieval, or as input to a small downstream predictor.

Hebbian SDR Adapter for Streaming Context Learning

Attach a local BCM-trained binary adapter to a pretrained or frozen encoder, allowing new graph nodes or streaming examples to acquire representations without backpropagating through the main network. The adapter learns only from positive co-occurrence statistics and maintains sparse codes, providing a low-memory continual-learning path.
