AlphaGo Zero: An overview of the algorithm

Jessica YungArtificial Intelligence, Highlights

In this post I go through the algorithms presented in the groundbreaking AlphaGo Zero paper using pseudocode. The objective is to provide a high-level idea of what the model does. Why AlphaGo Zero matters Last week, Google DeepMind published their final iteration of AlphaGo, AlphaGo Zero. To say its performance is remarkable is an understatement. AlphaGo Zero made two breakthroughs: … Read More

Questions to ask when deciding how to approach predictive problems

Jessica YungData Science

Is the situation stochastic or deterministic? Is it time-inhomogeneous? (Different across time?) How much data do you have available? What limitations are there with respect to computational cost (compute and time), both for training and predicting? Do you need to try actions to learn about situations? (If so, consider Reinforcement Learning.) Do your actions have an impact on the environment? … Read More
