The role of gain neuromodulation in layer-5 pyramidal neurons
Alejandro Rodriguez-Garcia, Christopher J. Whyte, Brandon R. Munn +3
Biological and artificial learning systems alike confront the plasticity-stability dilemma. In the brain, neuromodulators such as acetylcholine and noradrenaline relieve this tensi…
Dynamic gain neuromodulation attenuates the stability gap under joint training
Alejandro Rodriguez-Garcia, Anindya Ghosh, Srikanth Ramaswamy
Recent work in continual learning has highlighted the stability gap -- a temporary performance drop on previously learned tasks when new ones are introduced. This phenomenon reflec…
Improving the adaptive and continuous learning capabilities of artificial neural networks: Lessons from multi-neuromodulatory dynamics
Jie Mei, Alejandro Rodriguez-Garcia, Daigo Takeuchi +4
Continuous, adaptive learning, the ability to adapt to the environment and keep improving performance, is a hallmark of natural intelligence. Biological organisms excel in acquirin…
Augmenting learning in neuro-embodied systems through neurobiological first principles
Alejandro Rodriguez-Garcia, Anindya Ghosh, Jie Mei +1
Recent progress in artificial intelligence (AI) has been driven by insights from physics and neuroscience, particularly through the development of artificial neural networks (ANNs)…
