Overview

emergent is a comprehensive neural network simulator that enables the creation and analysis of complex, sophisticated models of the brain in the world; features:

  • Full browser and 3D GUI for constructing, visualizing, & interacting.
  • Accessible to non-programmers e.g., for teaching.
  • But also highly productive for experts, used daily in scientific research.
  • Powerful C++ scripting language, css (not that css), GUI Programming environment (IDE) -- transparent access to C++.
  • Rich, dynamic, embodied environments for training networks:
  • In use for decades, for hundreds of scientific publications from a variety of different labs. Detailed models of the hippocampus, prefrontal cortex, basal ganglia, visual cortex, cerebellum, etc available (also see textbook).
  • Direct descendant of PDP (1986) and PDP++ (1999).
