2018 Ice Hockey World Championships – predicted outcomes

Here’s the first real prediction from my Bayesian Inference Engine, on results for the upcoming Ice Hockey World Championships, starting in about 3 weeks from now. As usual, there are 16 teams, split into two groups: Group A : [‘RUS’,’SWE’,’CZE’,’SUI’,’BLR’,’SVK’,’FRA’,’AUT’] … Continue reading

Machine Learning – results

So, I reached the point where my Neural Network , after a couple of thousand training iterations, is capable of correctly identifying and separating different categories of input into their corresponding classes. More specifically, as “targets”, I’ve chosen a number … Continue reading

Machine Learning – normalizing your inputs

Often it pays off  to pre-process/normalize your input data before passing it further down the line of your Neural Network, eg. to get the range of input values into a scale more suitable for your network. Im experimenting with images, … Continue reading

Improving Python performance by factor of 100

I’m doing a bit of Machine Learning on my spare time. A neural network that analyzes images. Anyways, since I don’t have zillions of computing power, any decent amount of learning data takes hours and days to process thru my … Continue reading

The power of Machine Learning

https://www.theguardian.com/technology/2017/sep/07/new-artificial-intelligence-can-tell-whether-youre-gay-or-straight-from-a-photograph Machine Learning has an amazing ability to detect patterns where mere mortals fail to do so. As always, any technology can be used for good, as well as bad.

Neural Networks – training the network using an SGD

In order to understand how my chosen strategy for finding new weights, namely an SGD, actually operates, I did a bit of analysis. The graph below shows the flow of one single input, in a trivial, “linear” neural network, with only … Continue reading

Machine Learning

It’s been a while since I played with Machine Learning and AI. Last time I was using C++, this time I used Python & Numpy. A world of difference: although I no longer can find the C++ hack, I know … Continue reading
