Replay in Deep Learning: Current Approaches and Missing Biological Elements [article]

Tyler L. Hayes, Giri P. Krishnan, Maxim Bazhenov, Hava T. Siegelmann, Terrence J. Sejnowski, Christopher Kanan
2021 arXiv   pre-print
Replay algorithms have been successfully used in a wide range of deep learning methods within supervised, unsupervised, and reinforcement learning paradigms.  ...  Replay was first observed in biological neural networks during sleep, and it is now thought to play a critical role in memory formation, retrieval, and consolidation.  ...  For example, (Káli and Dayan, 2004) proposed a model where the HC and cortex were modelled as a lookup-table and a restricted-Boltzmann-machine, respectively.  ...

2021 Neural Computation  
Replay algorithms have been successfully used in a wide range of deep learning methods within supervised, unsupervised, and reinforcement learning paradigms.  ...  We identify multiple aspects of biological replay that are missing in deep learning systems and hypothesize how they could be used to improve artificial neural networks.  ...  For example, Káli and Dayan (2004) proposed a model where the HC and cortex were modeled as a lookup table and a restricted-Boltzmann-machine, respectively.  ...
