Fair enough - it’s funny too, I picked this username decades ago, after doing some AI research in college. It’s always fascinated me.
I wrote many fuzzy logic systems. Instead of just ranking inference system and requirements rules, I’ve built systems based on population and domain probabilities, meaning the “closer to” type of modeling. I went into neural networks with the properties discovery capabilities that AI is now into. That was true multidimensional calculus to discover the fliers in the data.
