Machine Learning
I started a new job running product for an AI startup, and it’s been pretty intense, not leaving much time to do my big TensorFlow conversion. But over the last week, I got back to it, and yesterday I got…

It’s been an eventful few days for my model. This entry is going to be a bit of a saga, but here goes. I had implemented the weighting function as described in my last post. I was getting great results…

Okay. Last post I wrote that it’s tricky to do a non-simplistic naive implementation of taking into account all the attempts. Actually, though, it’s not tricky at all, and when I originally thought about it weeks ago, I was so…

It’s been a while since I posted anything here, and in fact, a good while since I worked on this project. Shortly after my last post, school started for the boys, and that’s always a bit of a transition. Also,…

Built a quick (slow) framework to track board state and proposed illegal and legal moves for every game, and save out the game history for any game where the illegal move percentage spiked to higher than 98%. The vast majority…

So, with my new softmax back propagation sorted, I was excited to see how my model would perform, especially since softmax with MSE was my first hypothesis. Well, MSE was a disaster, although I didn’t push it too far. Softmax with…
Machine Learning
Note: This post is the ultimate result of my quest for how to do softmax backpropagation in my hand-coded model for this project. The actual math for softmax back propagation is not something that was specifically covered in my coursework….

…and it is not lost on me now that I may have had a problem with my gradients which I did not check… – Me, five days ago After taking a brief hiatus from my checkers AI to do some…
Machine Learning
A couple of days ago, I got all the machinery of my network in place and did my first test. I decided that for starters, using a network I wasn’t even sure worked for a problem I’ve never tackled before…
Machine Learning
Having established in my previous post that softmax looks like the way to go for my final activation layer it’s time to think about the cost function. And this one is trickier. Hypothesis: Use Mean Squared Error Cost Function The…
