This most recent work period involved a lot of refactoring and adding some new key functionality. Matthew asked me to create a simplified Action Type in addition to the one that was all in place, basically just the same actions without PRESSED and RELEASED. Since we still wanted the original structure to be there, all I had to do was cast the "complex" actions to "simple actions. Matthew then asked if I could convert that SimpleAction type into a matrix, so we could have a clearly defined Y.

This was also incredibly easy. I am actually quite happy with how it works as well. All you have to do to create an array for the action is two steps!

matrix = numpy.zeros(26)
if action is not SimpleAction.INVALID:
    matrix[action] = 1;

The 26 is the number of different Simple Actions we have. Then, to make it so we can run the parser separately from the Agent, I made it the replay can output numpy files for each character where each row in the file contains the frame of an action, and a collapsed matrix of all actions that happened on that frame.

(frame_index, collapsed_action_matrix)

After completing the numpy functionality, I went to edit the demo program to integrate it with our project. The first step of this was making the program use the new numpy framework instead of the hacked together framework I used for the demo. I also simplified a lot of the code so it should improve run time dramatically.

The next step that we are going to take, is to start training the agent. Now that everything is lined up properly, doing the training should not be too large of a task. This timeline should leave us with enough time to complete the project, which is a great feeling to have.

First I would like to discuss our goals and long-term plans. We want to create an artificial intelligence that learns how to play first-person shooters without access to any game state data other than what can be gained through the audio and visual buffers. In other words, the AI will only have access to the information that a human player would. If we are successful with these constraints, then I could see our work leading to AI that can play any game, or even AI-driven robots that can play games using mechanical hands and eyes to operate normal peripherals and interfaces.

We are currently in the research and planning phase of the project. This means that our job right now is to decide exactly what tools and technologies we will use and how they will interact with one another. By the end of the semester, which will arrive sometime this December, we will need to be ready for phase two, which is the development, training, and testing phase. Yes, that is all three at once. However, if …

Over the past couple of weeks, Matthew and I have been trying to narrow down our idea for capstone. We have settled on a "Modular" AI that can play First Person Shooters or other similar video games. However, we decided to put a slight twist on the idea of an AI playing games. Most of the AIs that are currently out have more information than they should possibly have at that time, like the location of players. We decided that our AI would only have information that would be accessible to a human player. We also noticed that many of the "PlayerAIs" out there are reactionary, not planning. While reacting is a key part to many of these games, so is strategy. We want to create an AI that thinks, at least a little bit, about that actions it is making or should make.

Since narrowing down our topic we have split off and started looking at different existing technologies and research that could help us understand and create this project. I decided to look at some computer…

Finally, our CSI-480 (Advanced Topics: AI) course material is catching up to where we need to be. We are covering perceptrons and sigmoid neurons in the lectures, and we are also using TensorFlow to solve some very simple introductory problems (via tutorials). To supplement this I have been reading Neural Networks and Deep Learning by Michael Nielsen, a textbook available for free on the internet, which dives into neural networks right from the first chapter. Additionally, I have been finding 3Blue1Brown's multi-part video series about deep learning to be extremely helpful for visualizing some of the more advanced concepts. Even if I do not fully understand the calculus and linear algebra involved, at the very least I have a better idea of what goes on inside of neural networks. For example: I know what loss and gradient descentalgorithmsdo, essentially, and I also understand how the latter helps find a local minimum for the former, but I do not necessarily feel confident in my …
