Hi, Both Moshe and Ben have touched on as aspect of this discussion that I have been thinking about for some time.
Moshe said, "I don't think that nodes+links are very good for reasoning about vision and space..." and Ben responded "I'll say now that neurons are basically nodes and synapses are basically links, so it's clear that a node-link data structure in itself isn't way off..." There is an important difference between neurons and synapses located in a physical brain and artificial nodes and links located in a computing system. In a biological brain closely associated neurons are 'generally' close to each other physically. Whilst, artificial nodes and links are generally not. For me this seems to lose a whole layer of information. The patterns related to the interconnectedness are there but the information related to the spatial layout of the nodes is lost. It would seem that this information could be useful for both spatial reasoning and more general reasoning. Is there any value in having nodes located in a virtual n-dimensional space? One of the advantages that artificial systems have over biological systems is that the cost of long distance links/synapses is no more expensive that short distance connections. (Where cost is directly related to distance between nodes/neurons.) Is this a good thing though? Would a way to calculate cost of connection using distance be useful?
