We are no longer developing this software. We are now developing a new framework based on the
Go language, with a
Python interface: https://github.com/emer/emergent
The current release built from github sources (source code only) is: https://github.com/emer/cemer/releases/tag/v8.6.1
The latest release with built packages is: https://github.com/emer/cemer/releases/tag/v8.5.2, released Feb, 2018.
The main dependency files for current releases are found in: https://github.com/emer/cemer/releases/tag/v8.5.1
This github repository was converted from the svn original, and has captured the full history of git tags (including historical dates!) in: https://github.com/emer/cemer/tags
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
- But also highly productive for experts, used daily in scientific research.
Powerful C++ scripting language,
css(not ''that'' css), GUI
Programming environment (IDE) --
TypeAccessaccess to C++.
Rich, dynamic, embodied environments for training networks:
DataTablefor network inputs and
DataGen(filtering, grouping, sorting, dimensionality reduction, graphing, etc).
Newtonian physics simulator for Virtual Environment, e.g., a biophysically realistic human arm, and realistic embodied, dynamic vision.
Sensory filtering for vision, audition, and vocal-tract speech.
Many classic neural network algorithms and variants: Backpropagation (e.g., deep convolutional neural networks), Constraint Satisfaction, Self Organizing, and the Leabra algorithm which incorporates many of the most important features from each of these algorithms, in a biologically consistent manner. Also, symbolic / subsymbolic ACT-R.
- Highly optimized vector-based back-end code with thread-specific memory allocation, and GPU (CUDA); Convenient compute cluster for GUI-based job control and data management.
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.
- Direct descendant of earlier simulators: PDP (1986) and PDP++ (1995).
