Q learning
This post discusses temporal difference (TD) methods, used in Reinforcement Learning. It contrasts TD methods with Monte Carlo (MC) methods and dynamic programming. You need to have a thorough understanding of Markov Decision Process (MDP) to understand this post. Prediction and Control : In general, RL methods have two components 1) Prediction / Evaluation : where […]
This post assumes that you have a strong understanding of the basics of Reinforcement Learning, MDP, DQN and Policy Gradient Algorithms. You can go through Policy Gradients to understand the derivation for Stochastic Policies In the previous post on Actor Critic, we saw the advantage of merging Value based and Policy based methods together. The […]
#CellStratAILab #disrupt4.0 #WeCreateAISuperstars #AlwaysUpskilling Reinforcement Learning (RL) refers to training agents with help of incentive-driven environments. RL typically involves a tuple of <state, action, reward> paradigm, which means that the agent has action choices to make in various states, and each action entails a potential reward. This also means that each state has a “value” […]
#CellStratAILab #disrupt4.0 #WeCreateAISuperstars #AlwaysUpskilling Minutes from Saturday 14th March 2020 AI Lab Workshop at BLR :- Session Presenter : SHUBHA M., Deep Reinforcement Learning Researcher, CellStrat AI Lab Last Saturday, our Reinforcement Learning Team Lead Shubha M. presented a fantastic presentation and workshop on Actor-Critic method used in RL. She also demonstrated a demo of this technique for Stock Market predictions. […]
I conducted an Introductory session on Reinforcement Learning Policy Gradients (PG) at CellStrat AI Lab on 1st Feb 2020. The goal of this session was to explain the basic underlying principle of Policy Gradients. The session started off with a quick recap of Reinforcement Learning, so that the audience is well aware of the definitions […]
#CellStratAILab #disrupt4.0 #WeCreateAISuperstars Last Saturday saw some amazing sessions on advanced AI at the CellStrat AI Lab meetup. Diabetes prediction with Machine Learning :- First came a superb presentation by Dr Purnendu Das on diabetes prediction using ML. Dr Das started by discussing the data sources for healthcare and clinical data analysis. He covered the […]
#CellStratAILab #disrupt4.0 #WeCreateAISuperstars Last Saturday, our team lead for Reinforcement Learning (RL) Shubha Manikarnike presented a fabulous hands-on workshop on RL and it’s various algorithms such as Markov Decision Process (MDP), Policy Gradients, Bellman equation, Q-learning etc. The session started with an Introduction to RL. There was a comparison on how this is different from […]
