This paper introduces a mechanistic neuronal network model for multilayer learning, offering biological insights and an alternative to backpropagation.
This paper proposes Hierarchical Block-Local Learning (HBLL), a framework for training deep neural networks without full end-to-end backpropagation, achieving $\mathcal{O}(\log N)$ parallel time compl…
This paper presents a Noise-modulated Neural Network (NNN) that learns and infers with noise, reconstructing backpropagation from forward-pass statistics alone.
While backpropagated gradients can predict human brain activity in the visual cortex, their spatial and temporal organization fundamentally diverges from the expected patterns of a biologically plausi…
