QUEST Discussion Topics, Oct 14

QUEST topics Oct 14

1.) Topic – the first topic this week is to address the Westercamp ATR single and multi-sensor diagrams from the QUEST perspective – Goal is to redraw the Westercamp ATR diagrams compliant with QUEST sys1/sys2 – make them situation based instead of concept encoding based – everything in context – the multi-sensor diagrams are pushing that way already! – what is sys1 and what is sys2 in those diagrams? Then applying our tenet that the fundamental unit of cognition is a situation how can we implement a general approach to ATR that is situation based! The goal of our proposed Burka lab idea is to focus on a new direction in layered sensing exploitation – situational pattern recognition. So we want to define situations and apply that definition for the functions we seek in ‘ATR’ (tracking, ID, …). Then I want to review a recent example from the VIRAT researchers that is related to our view of situations and relate it to this revamp of the Westercamp ATR diagrams. The Virat work to be discussed is related to some of their publications.

2.) We’ve proposed one Burka lab experiment to investigate the application of QUEST concepts to solve the problem of what bits to exploit and at what resolution in a layered sensing environment. The idea is that we don’t have the option of processing all bits sensed for all possible meanings so we need an approach to decide what we look at and how we look at it – Attention (Dr. Young is developing a lecture for us on the modern views of attention). The best analogy is snail mail. When we go to the mail box we sort the material at different levels of resolution. Some things we discard by just looking at the envelope. Some we read the details of the source then discard. Some we actually have to open to discard. Some we have to read all the contents to decide how to process. The idea is to architect a multi-resolution Burka experiment where conflicts between the ‘simulation’ (sys2 representation) and the observations at coarse resolutions can drive exploitation resources and when those conflicts don’t exists we can avoid expending those exploitation resources and potentially not drown in that data. We specifically want to add the details for ATRs and Trackers. We would also like to discuss the potential integration of human analyst in this discussion using technology to measure their sys1 response to a given set of data at a given resolution. We will examine the devices offered by the company Affectiva for this purpose.

3.) Also, a paper from Trevor detailing a philosophical take on dealing with occluded objects using mental imagery with perception.
