DARPA Developing Video Parser 29

coondoggie writes with an article in Networkworld about a disconcerting DARPA project. From the article: "If a picture is worth a thousand words, the scientists at the Defense Advanced Research Projects Agency would like to make that about a billion with a new software intelligent program. DARPA this month said it will detail a new system it would like to see built known as the Visual Media Reasoning (PDF) program. The main idea is to develop an advanced software program that can 'turn 'dumb' unstructured, ad hoc photos and video into true visual intelligence.'"

    Why not design a connectomics informed system [utah.edu] that mimics the neural retina and visual system? Something that takes the results of research like this and uses true biologically informed computing to do what neural systems are good at and silicon based systems are not so good at? After all, what they are looking at is a system that works like a retina works (more like a video camera and not a still camera), so why not go to the biology which is really good at comparing like streams of information and making like or not like decisions.

    More traditional background on retinal design and research can be found here [utah.edu].

    The eyes do not "see" in the sense of processing information. They turn light into nerve impulses. Ho-Hum. We've got that, in fact this isn't about that at all. They are dealing with already captured data anyway.

    so why not go to the biology which is really good at comparing like streams of information and making like or not like decisions.

    Yeah, biology is really good at making decisions. Shame that not a single person on earth has a system that can replicate it. Nothing even close. Biology is fantastic, but it falls over flat when we try to replicate it on a computer. This is due in large part because a brain tends to have more "power" to throw at the problem by many orders of magnitude. It is also differently abled compared to a computer, we can't just scale up and hope to emulate it, need the special hardware-software combo that is our beloved wetware.

    Let us say that a bio-technical solution was somehow brought to bear on this problem, someone wasted a wish perhaps. Then you get... what? What biological process or technique can be used here? The ability of mamals to discern individual objects in a scene? Then how to classify them? After a scene has been broken down by the biological side how is it turned into useful information? The mind would have to hand off some information at some point. Images suck because computers can't do that well yet (hence this project) and tokens representing actions and objects seems impossible for quite some time, it would resemble the complexity of a human mind.

    Nothing in biology can be applied to this problem directly, only perhaps simple ideas applied rigorously. Stop spouting your favorite rubbish.

    Actually they do process information. The neural retina is like a miniature parallel supercomputer at the back of your eye that does initial signal processing from the photoreceptors through the over 50 kinds (200 in other invertebrates) of neurons.

    No offense friend, but I can't figure out if this is a troll or that you are simply uninformed here. Biological neural systems are *very* good at discriminating differences in data streams. Nested neural systems then further refine those abstractions and you get more advanced logic. The problem in the past has been discerning what those connectivities are as most current models of neural connectivity grossly underpredict the biological reality of neural circuit complexity.
