QUEST Discussion Topics and News, Aug 19 2011

Weekly QUEST Discussion Topics Aug 19

1.) Topic one is to continue the brainstorming session on the open source layered sensing simulation model (BURKA lab experiment) and its potential use as the sys2 cognition engine for a quest agent. Last week we suggested emphasizing a Knowledge engineering video analysis application twist:
a. Modify Current KEVA / VIRAT Capability:
i. Index, track, relocate objects of interest in stored and new still and streaming imagery
We want to extend the discussion to a potential to investigate the use of a VIRAT like technology (activity recognition in streaming or stored video). The sorts of questions we would want the BURKA lab QUEST agent solution to answer: Finding an OOI at various size and aspect angles – once an OOI has been chosen you can start a series of link generations (what frames is it in, what entities is it associated with – situation based analysis, on multiple soda straws simultaneously…) What road is it on – how did it get there – are there other cars ‘associated’ with it – did it stop anywhere? Find it where ever it is in a stored data set – also extract the ‘situations’ that define those located data sets. In a VIRAT like environment how can we take a relatively fragile description of an activity and make it a more robust representation. This discussion led us down the path of why generate the simulation (except when needed for the humans involved in the quest solution to get insight into the computer quest agent’s representation). There were a series of emails that we would like to review on opinions on generation of the simulation – why or why not generate it and how to use it? Hopefully Mike Young, Brian Tsou and Scott Weir will provide their views and Capt Amerika will then present his view of how the sys2 ‘simulation’ provides the context to construct situations. The Capt Amerika view will include a short discussion on ‘filling in’ and philosophical issues and implications on ‘simulations’. As a reminder we are using the word simulation in a unique way – we are not talking strictly about running in the background a program to compare alternative outcomes based on proposed action. We are suggesting that an internal representation that is composed of both measured and inferred data is used, that is what we call the sys2 illusory representation = qualia = simulation, is used to reason with to deliberate with. The word simulation is used to emphasize the point that we aren’t creating a sensor data blackboard and then reasoning off of that. The implication of the inferred data to provide context is key and thus the word simulation. Capt Amerika will propose a multiresolution Burka experiment where conflicts between the simulation 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. A simple WAMI test case will be discussed. Also we would like to return to our prior discussions on blindsight – the reason being is it provides us insight into sys1 and sys2 representation of visual data – similarly there is the analogous issue of ‘numbsense’ in the somatosensory channel.

2.) Topic two when we eventually get to it is the recent Sci Amer ‘Mind’ issue July 2011, a word doc with some snippets from some of the articles can be provided to stimulate discussion.
