Beginner’s Guide to Developing with NuPIC

Scott PurdyMay 3, 2014

Levels of Abstraction

• Algorithms– Encoders– Spatial Pooler– Sequence Memory (Temporal Pooler)– CLA Classifier (not covered)

• Networks and Regions – supports topology• Online Prediction Framework (OPF)

– CLAModel (network and algorithm wrapper)– OpfRunExperiment.py– run_swarm.py– experiment.json (not covered)

Interactive work with ipython notebook:http://nbviewer.ipython.org/url/fer.io/~scott/nupic_overview.ipynb

Network and Regions API

• Supports arbitrary topology• Formalizes serialization (but delegates

implementation to each region)• Handles data flow through network
