Hello! Several weeks ago I've announced my NeuralNetworks project. Thank you very much for your ideas and feedback. As suggested, I wrote examples for every class and tested my perceptron on linearly-separable logical functions. I have just completed a post about my implementation of a single-layer perceptron: https://medium.com/@i.oleks/single-layer-perceptron-in-pharo-5b13246a041d. It has a detailed explanation of every part of the design and illustrates different approaches to implementation. Please, tell me what you think. Are my class diagrams correct or did I mess something up? Is there a design pattern that I should consider? Do you think that I should do something differently? Should I improve the quality of my code? Yours sincerely, Oleksandr
