Today on the show, Lan presents a blog post from Google Deepmind about Dopamine and temporal difference learning. This is the story of a fruitful collaboration between Neuroscience and AI researchers that found the activity of dopamine neurons in the mouse ventral tegmental area during a learnt probabilistic reward task was consistent with distributional temporal-difference reinforcement learning. That's a mouthful, go read it yourself! George presents his first attempts at designing an Auto-Trading Agent with Deep Q Networks. Last but not least, Kyle says "Hey Alexa! Sorry I fooled you ..."
