Collective-Detectability Information Fusion for Asynchronous Latent States

Replace arithmetic averaging of local latent means or covariances by diffusion of Gaussian natural parameters. Each asynchronous encoder contributes its local observation information, while graph diffusion combines complementary information from agents that individually observe only subsets of the latent state. The fused latent posterior can then drive a recurrent world model, graph neural network, or decentralized multi-view predictor.

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.
