Interesting Chess Math/Simulation Problem

In the movie "Queen of Katwe", there was a kid that insisted that her queen can not be captured and wouldn't let the other kids capture it. Of course, this gives a great advantage. But, how much of an advantage? Is it the same as a queen odds handicap or more or less? You start with both having quee...

Re: methods for tuning coefficients

Pretty sure your Temporal Difference Learning is implemented incorrectly (and highly inefficient) if you are only propagating WDL back. TDL's "oracle" should be the engines own search() The idea being to push the static evaluation of the current position towards the score returned by a search of it...

Re: methods for tuning coefficients

Think of this: The static position eval is of the form: v = Sigma Ci x Fi where C are coefficients and F are features. Now compare that to the equation for an SLP (single layer perceptron = a neural network with only one weight layer): O = Sigma Wi x Ii where W are weights and I are inputs. These eq...

Re: What is Deep Learning?

It is a new term for an old thing. In the field of ANN's (Artificial Neural Networks) / CI (Computational Intelligence) we used to classify NN's in several ways but one way was SLP vs MLP. SLP is Single Layer Perceptron and MLP is Multilayer Perceptron. SLP has inputs, one set of weights and outputs...

They said they were playing chess and one of them said he couldn't teach me because I was too dumb to learn chess. We were in the elementary school library, so I read the chess sect...
