Computation graph of some commonly used optimizers: SGD, RMSProp, Adam. Join Ordering via Reinforcement Learning. However, picking the wrong optimizer can have a substantial negative impact on the performance of your machine learning model [1][2]. First published in 2014, Adam was presented at a very prestigious conference for deep learning practitioners — ICLR 2015.The paper contained some very promising diagrams, showing huge performance gains in terms of speed of training. By observing, performing an action on the environment, calculating a reward, and evaluating the outcome over time an AI agent can learn to achieve a specific task or sequence of decisions needed to execute a task. The main insight of our work is the following: instead of solving the join ordering problem using dynamic programming as shown above, we formulate the problem as a Markov Decision Process (MDP) and solve it using reinforcement learning (RL), a general stochastic optimizer for MDPs. Set the learning rate for the representation to 0.05, and set the gradient threshold to 1. Reinforcement Learning has delivered excellent results in problems with similar premise like video games and board games where they have far outperformed humans.
