So I had the nice opportunity to build a stationary computation horse.

The underlying dynamics is that a few individuals have a lucky streak.

It will after training hopefully have good performance on this training set. Specifically, the tools for training a…mathowl in #hive-196387 • 2 years agoResearch diaries #16: Reservoir computing, an AI which does not live inside a computerIn this post we will look at a fancy AI called reservoir computing. We will just be looking at the general concept. In a future post I will show you an implementation of this…mathowl in #hive-196387 • 2 years agoResearch diaries #15: Going down rabbit holesIn math everything you do has always to be consistent with the rules of logic. But the real goal of math is finding structure inside the logic.

Today we will be looking at a famous paradox about why correlation does not have to imply causation.

The fundamentals were only completed around the 19th century.

As we progress through a sequence it could be that these points are approximating some point. For example, look at the graph below  at the start of a night out.
