1. Beginner’s Guide to Developing
with NuPIC

2. 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)

3. Interactive work with ipython notebook:

4. Network and Regions API
• Supports arbitrary topology
• Formalizes serialization (but delegates
implementation to each region)
• Handles data flow through network
