The algorithm recently proposed by Krotov and Hopfield \\cite{krotov_2019} can be utilized to mirror this process in artificial neural networks, where its built-in intra-layer competition and selective inhibition of synaptic updates offer a cost-effective remedy for the lack of lateral connections through a simplified attention mechanism. We demonstrate that KH-modulated RBMs outperform standard (shallow) RBMs in both reconstruction and classification tasks, offering a superior trade-off between generalization performance and model size, with the additional benefit of robustness to weight initialization as well as to overfitting during training.", "revisions": [ { "version": "v1", "updated": "2025-05-11T08:51:15.000Z" } ], "analyses": { "keywords": [ "robustness", "neuromodulation tunes synaptic plasticity", "krotov-hopfield", "built-in intra-layer competition", "synaptic updates offer" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
