Overview
The AI Inspector is a tool that enables you to “see inside the brain” of the AI.
In other words, it shows you a current view of the policy mapping. You can see what the AI’s action would be given a certain state. With this information you can design better training, targeting specific improvement areas.
What are the State(s) in AI Arena?
The state is a snapshot of the environment at any point in time. The AI uses this observation to decide what to do. In other words, the state is the context used in the neural network's decision making processÂą.
For example, some researchers use all of the pixels on the screen as the state, and let the AI figure out what the pixels represent. Other researchers hand-craft features based on their opinion of what is important in the decision making process.
For AI Arena, we hand-crafted the features because we want to constrain the size of neural networks used.
Why? We want equal opportunity. By avoiding the use of Convolutional Neural Networks (CNNs), which can be computationally intensive—we reward users for being able to train their AIs better, not for having more computational resources.

Notes:
- The state does not encapsulate all of the information of the environment, just what the AI researcher deems necessary.
