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: DataTable for network inputs and data processing, analysis, generation (filtering, grouping, sorting, dimensionality reduction, graphing, etc). Newtonian physics simulator for robotics simulations, e.g., a biophysically realistic human arm, and realistic embodied, dynamic vision. Sensory filtering for vision and 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 available (also see textbook). Direct descendant of PDP (1986) and PDP++ (1999).

After downloading, right click and select open. LTS emergent7 compatibility package: emergent-7.1.0-10018-mac64.dmg (depends on 8.0.0 install) Ubuntu Instructions Our apt repository contains packages for emergent 8.0 for the LTS 16.04 and 14.04 releases. There are older versions of emergent for earlier versions. See Build Linux for help building the latest version from scratch. HTTP download or FTP download You can find older binary packages for emergent and source packages for all of its prerequisites on the HTTP download or FTP download sites (same source, just different TP).
