Understanding Policy Gradients: Definition, Explanations, Examples & Code
Policy Gradients (PG) is an optimization algorithm used in artificial intelligence and machine learning, specifically in the field of reinforcement learning. This algorithm operates by directly optimizing the policy the agent is using, without the need for a value function. The agent's policy is typically parameterized by a neural network, which is trained to maximize expected return.

Overview of Policy Similarity Metric (PSM)
Policy Similarity Metric (PSM) is a similarity metric, used in reinforcement learning or machine learning, that helps measure how similar the behavior of one state is to another. In this context, a "state" refers to the situation or environment in which an AI agent operates or makes decisions.
The main idea behind PSM is to assign "similarity scores" to different states based on how similar the optimal policies (i.e., the best decision-making strategi
Polyak Averaging is a technique used to optimize parameters in certain mathematical algorithms. The idea is to take the average of recent parameter values and set the final parameter to that average. The purpose is to help algorithms converge to a better final solution.

Introduction to Pose Disentangling
When humans interact with the world, we have a remarkable ability to extract crucial information about our environment quickly. We can tell if something is moving or stationary, if an object is nearby or far away, and what direction it is moving in. Part of our ability comes from our perception of 'pose,' which is the position and orientation of an object relative to its surroundings. Pose is not only relevant in human perception, but also in how computers 'se
