Local Pheromone Network: Sparse Local Learning with Multi-Scale Synaptic Trails, Consolidation, and Replay
arXiv:2606.30669v1 Announce Type: cross Abstract: Backpropagation-trained dense neural networks are powerful function approximators, but they couple learning across many parameters and can overwrite previous associations when tasks conflict. This paper describes Local Pheromone Network, a small research prototype for sparse, local, manually updated neural networks. In Local Pheromone Network, each output unit reads only a fixed local neighborhood of input units subject to geometric distance and molecular-tag compatibility. Each synapse stores a weight, a short-term pheromone trace, a long-term
The continuous pursuit of more efficient and biologically plausible AI learning mechanisms drives research into sparse, local networks, addressing limitations of current dense models.
This research explores a fundamental shift in neural network architecture that could lead to more robust, energy-efficient, and incrementally learning AI, impacting scalability and deployment.
Traditional backpropagation-trained dense networks face challenges with catastrophic forgetting and computational cost; this work proposes an alternative local learning paradigm.

The prototype demonstrates a method for sparse, local learning that mitigates catastrophic forgetting in AI models.
Successful development of such architectures could lead to a new class of more versatile and adaptive AI systems requiring less re-training.
This could enable more robust on-device learning and reduce dependency on large, centralized, and constantly updated foundational models for specific applications.
