Testing biologically inspired learning against the strategic depths of chess
Testing biologically inspired learning against chess reveals a clear gap between ambition and results. A 44.9M parameter Sparse Predictive Hierarchy, built on local learning rules, failed catastrophically against a tiny 3.8M CNN trained with standard backpropagation. The extreme ~99% sparsity choked tactical information flow, proving that local updates struggle with global credit assignment in dense, long-range domains. This negative result is valuable, it sharpens the question of whether biological learning can ever scale to tasks requiring strict global feedback.
Discover how a tiny AI model generates faces directly on a microcontroller.
A 128x128 image of a face, generated from scratch in about 20 seconds on a microcontroller that fits in your pocket. That's what one developer achieved with a latent flow transformer, compressing 2.4 to 4 million parameters into int8 and streaming weights from flash via DMA. The clever part is the ReLU² activation, which creates sparsity that skips calculations entirely. It's a practical lesson in efficiency, not just a demo.
Beyond the Hype: A Practical Guide to Sparse Attention Claims
Reading how a practitioner can make sparse attention look deceptively strong, through careful benchmark selection, unoptimized baselines, and aggregate reporting, is both uncomfortable and necessary. The honest admission that even good-faith researchers fall into these traps makes it more valuable, not less. This isn't about dismissing the field but about demanding rigor where it's easy to cut corners. For anyone navigating efficient attention research, it's a practical warning worth internalizing before your next evaluation.
