Vector Symbolic Architectures in Clojure

A few days ago I run into Carin Meier post titled Vector Symbolic Architectures in Clojure. Beside this point that I can really relate to […] I don’t have a lot of free time. When I do get a few precious hours to do some coding just for me, I want it it to be small enough for me to fire up and play with it in a REPL on my local laptop and get a result back in under two minutes....

A More Connected Approach to Notes

I have recently been using tools like Athens research and LogSeq for connected note taking (see my previous post). A key thing you may want to check before choosing the one you will use is the lincese of each. As I write these lines Athens is friendlier if you plan to use it for work. LogSeq one, unfortunately, not so much. However if you plant to use it for fun, LogSeq is feature packed, the team keeps delivering and outstanding product, and the new publishing capability is great....

Genetic Programming, The Multiplexer and DEAP

Learning classifier systems (LCS) and Genetics-Based Machine Learning (GBML) have been using the multiplexer problem as a toy problem because of its properties; among others, its dynamic dependencies based on the input values and the exponential nature of the required solution as a function of the number of inputs. There is a great introduction why the multiplexer is interesting for LCS and GBML systems at Wilson’s XCS field-defining paper. A simple definition [1] of the multiplexer is as follows:...
