NuPIC is an open source project based on a theory of neocortex called Hierarchical Temporal Memory (HTM). Parts of HTM theory have been implemented, tested, and used in applications, and other parts of HTM theory are still being developed. Today the HTM code in NuPIC can be used to analyze streaming data. It learns the time-based patterns in data, predicts future values, and detects anomalies. NuPIC includes discussion groups on HTM theory, research on extending HTM, and source code for complete applications based on HTM. We welcome participation in all of these areas.
