A modular cognitive architecture from Carnegie Mellon University designed to simulate human thought processes through rule-based symbolic and subsymbolic systems.

John Anderson's team at Carnegie Mellon University developed this architecture to model the discrete steps of human cognition. The system functions through a series of modules: declarative memory stores facts (chunks) while procedural memory executes rules (productions). It operates on a 50-millisecond cycle to mirror actual human neural processing speeds. Developers use ACT-R to build intelligent tutors for mathematics and high-fidelity pilot simulations for the Department of Defense. It translates psychological theory into executable code to predict how humans learn, forget, and react under pressure.

### [Cognitive Architectures -- A principled way to build agents](https://singapore.aitinkerers.org/talks/rsvp_9GgmNHjgPsk)

In the quest to build artificial intelligence, could understanding natural intelligence help? Cognitive architectures is the field of understanding and implementing the various building blocks of intelligence in cognitive science, offering a principled way to build agents. In this demo, I'll show some basic blocks that I've built and assembled into a coding agent.
