How to build a General Intelligence: An interpretation of the biology

Figure 1: Our interpretation of the Thalamocortical system as 3 interacting sub-systems (objective, subjective and executive). The structure of the diagram indicates the dominant direction of information flow in each system. The objective system is primarily concerned with feed-forward data flow, for the purpose of building a representation of the… Read More »How to build a General Intelligence: An interpretation of the biology

How to build a General Intelligence: Circuits and Pathways

Figure 1: Our headline image is from the Cognitive Consilience: An atlas of key pathways cross-referenced to supporting literature articles. The complexity and variety of routing within the brain can be appreciated with this beautiful illustration. Note in particular the specialisation of cortical cells and the way this affects their… Read More »How to build a General Intelligence: Circuits and Pathways

New HTM paper – “Why Neurons Have Thousands of Synapses, A Theory of Sequence Memory in Neocortex”

The artificial neuron model used by Jeff Hawkins and Subutai Ahmad in their new paper (image reproduced from their paper, and cropped). Their neuron model is inspired by the pyramidal cells found in neocortex layers 2/3 and 5. It has been several years since Jeff Hawkins and Numenta published the… Read More »New HTM paper – “Why Neurons Have Thousands of Synapses, A Theory of Sequence Memory in Neocortex”
