one thought i had is that dreams are so personal so energetic street footage doesn’t convey the emotivity. thats a tough ledge to get around.
How can you compare a person’s lifetime of experiences with an installations life of 10 days in a shop window? Things could/would only really get interesting with a huge network (I upgraded my machines to 4GB, and am using a different method to make the patch as scalable as possible) so we’ll see how far I can push it. Also there is the aspect of storing components of stimulus, rather than images, which could allow the construction of imaginary memories. No idea how that would work currently. I have spoken briefly to Gabora about the emotional aspect. I’m playing with (the still Piagetian idea) that emotions could all be reduced to low level emotions related to biological state.
If all knowledge is based on sensor data (as in the Piagetian project) then why, Gabora asked, would a gun associate closely with a knife? They have little to do with one and other as sense-data is concerned. My answer was that perhaps they are bound not just by their sensor impressions, but also (and perhaps more importantly) by their effect on our internal state. They associate with one and other because they cause a similar emotional state.
The problem with that line of enquiry (for my phd) is that it would require a model of those low level emotions. Interestingly the character of those emotions would just be another channel of sense data fed into he SOM. I have still not yet figured out how to deal with multiple channels of sense data, the current idea is have a SOM for each channel, which are cross linked by temporal correlation. A free association could then move through the space of similar images, and then cross into a free-association of sound where the sound matches the image. Then cross into emotion… Ideally this should be an nD SOM, with 2 dimensions for every sensor channel. I can’t get my head around this part.
A measure of stimulation would be very interesting, where the cross-link happens where the stimulus is very strong in the SOM. (A strong stimulus could be as simple as a very close similarity between the activated unit and the input stimulus)
