The approach presented here begins with two separate Al systems, OpenCog (introduced in Chapter 6.3) and DeSTIN (introduced in Chapter 4.3.1) - both currently implemented in open-source software. Here are the relevant fe

What we describe here is a way to make a "Uniform DeSTIN", in which the internal repre- sentation of perceived visual forms is

No doubt it will evolve in some respects as implementation progresses; one of the principles kept in mind during the design and development of OpenCog was modular- ity, enabling substantial modifications to particular parts of the framework to occur without requiring wholesale changes throughout th

For instance this may be effected by a process that, each cycle, causes a certain amount of STICurrency to pass to schema satisfying certain properties (those involving physical action, or terminating rapidly).
