@DeepMindAI We worked with @harvardbrainsci to show that distributional RL, a recent development in AI research, can provide insight into previously unexplained elements of dopamine-based learning in the brain. Read the blog: t.co/5CSlVHE7Y6 (2/2)
@StefanLang_MD very exciting work, also a great blog post to go along with it. t.co/iUyZpUJQAZ t.co/gTf6tlXPJP
@StephaneFaure34 Analogy between advanced reinforcement learning and dopamine system mechanisms. Ain't understand everything but enough to be intrigued #AI t.co/EPMnGqCHaM
@taniajacob Some interesting research in distributional reinforcement learning, reconstructing a reward distribution from the firing rates of dopamine cells alone, a close match to the actual distribution of rewards in tasks that mice were engaged in.  t.co/K3l72lfyKB
@KrystalBall_ai #Dopamine #DeepLearning “In artificial reinforcement learning systems, this diverse tuning creates a richer training signal that greatly speeds learning in neural networks, and we speculate that the brain might use it for the same reason.” t.co/iKxaGy2WxK
@GazeCoin DeepMind researchers have released a paper revealing links between machine learning, and the way human brains release dopamine. t.co/NRhElunmb3
@andyextance Surprised not to see more coverage of this Google Deepmind paper about how we think. My thoughts: a) How cool! b) Do we trust Google with this knowledge? Dopamine and temporal difference learning: A fruitful relationship between neuroscience and AI t.co/WPKtyxf0gE
@viajesubmarino A very nice read about the latest DeepMind paper on dopamine in the brain and RL: DeepMind: Dopamine and temporal difference learning: A fruitful relationship between neuroscience and AI t.co/nC90aKOek7
