In the previous article, we looked at the Actor-Critic, A2C, and A3C algorithms for solving the ball-find-3 problem in Grid World and did an action visualization to see how the agent interpreted the environment. A3C was a high-performance algorithm with a simple idea of using multiple agents instead of a...

In the previous article, we looked at several methods to improve the performance of the DQN algorithm and the Deep SARSA algorithm to solve the ball-find-3 problem in Grid World. Today we will look at Actor-Critic algorithms that outperform previous algorithms in ball-find-3, and visualize agent actions. We will also...

 Value Function and Discount Rate In the previous article, we introduced concepts such as discount rate, value function, as well as time to learn reinforcement learning for the first time. The two concepts are summarized again as follows. Discount Rate: Since a future reward is less valuable than the...

 What is reinforcement learning? In 2016, AlphaGo versus Lee Sedol became the topic of the event in which artificial intelligence won the worldâs first professional supremacy in Baduk. In 2018, OpenAIâs researchers at DOTA2, a 5-to-5 team-fighting game, won a pro-amateur team in a pre-determined heroic confrontation, and in...

âCanyonâ by iq  Introduction Shader is a language used to render computer graphics, primarily light and shadows. With the development of hardware, especially the GPU, Shader is now able to express many things that previously could not be expressed as performance problems. Shadertoy is an online shader code sharing...
