Double Fractal with 3D Prototype

Double Fractal was first created in the 90s and was the result of a passion for fractals and fractal math. Since then, it has grown including many unique fractals invented by its author. Some fractals were found by chance in 2001 when functions used for artificial intelligence were plotted as fractals. These new fractals were called JP Random Sets. The brilliant environment Lazarus allowed Double Fractal to be ported from Delphi and now Double Fractal can be run on Windows, Linux and MAC OS X. Fractals are infinite complex images defined by a finite definition. We find in fractals a model to understand many different sciences such as economy, health and weather. Many scientists love fractals. Double Fractal is a program that creates fast and easily high complex images. No specific knowledge is needed to use this program, it is a program that can be run just for fun. Please enjoy the better than ever Double Fractal 3 with its brand new 3D JP1 Set prototype.

Conscious Artificial Intelligence

This project is a quest for conscious artificial intelligence. A number of prototypes will be developed as the project progresses. This project has 2 subprojects: Object Pascal based CAI NEURAL API - https://github.com/joaopauloschuler/neural-api Python based K-CAI NEURAL API - https://github.com/joaopauloschuler/k-neural-api A video from the first prototype has been made: http://www.youtube.com/watch?v=qH-IQgYy9zg Above video shows a popperian agent collecting mining ore from 3 mining sites and bringing to the base. At the time the agent is born, it doesn't know how to walk nor it knows that it feels pleasure by mining. He has tact only (blind agent). The video shows learning, planning, executing and plan optimization.
