Agenda• Why Weak AI is not intelligent
• Cortex anatomy lesson
• The power of the pyramidal neuron
• Layers within columns
• HTM Theory details: SDRs, Spatial Pooling, Temporal Memory
• HTM Sensorimotor Theory details
Weak AI won’t produce Intelligence
what’s missing?

Sparse Distributed Representationshow neurons encode information
EncodersExample: Date Encoding
Spatial Pooling
• proximal feedforward input activates mini-columns• normalizes sparsity of encoded representation• maintains semantic meaning of representations
ProximalDriver Signal
Distal
Temporal Memory
• identifies context of input based upon distal segments• works within structure of mini-columns• puts cells into predictive states for next time step
