NACE (Non-Axiomatic Causal Explorer)

Responsible: Patrick Hammer, Peter Isaev

An experiential learning agent achieving 1000x data efficiency over deep RL. Constructs logic-based environment models through direct interaction, using curiosity-driven exploration and Non-Axiomatic Logic for evidential tracking.

</> Example Implementation
Curiosity-driven exploration
Shows NACE's curiosity-driven loop where prediction errors drive model refinement and exploration.
