OSARA Talks Online

OSARA conference link, with highlights from Ken Chiacchia's talk.

The Ohio SAR Association conference has posted their 2013 talks online.

Note particularly:

Ken Chiacchia's talk

Ken Chiacchia's talk, "ESW in the Alleghenies,"  includes our most recent AMDR work, and much more.  For example, he describes how to measure sweep width for a dog team.  The key idea is treating the dog-handler team as the sensor.

Detection by a Dog-Handler Team

Ken also compared time to reach a coverage of 2 (or 86% POD) of a dog team and a human team, in some conditions:

Time-to-Coverage for a dog-handler team vs a two-human team. (Chiacchia)
Time-to-Coverage for a dog-handler team vs a two-human team. (Chiacchia)

Use the dogs where they give the biggest gain: here, full foliage, low-vis.  There is no useful gain in the high-vis leafless condition.

Also make sure to see his work on the effect of convection on sweep width (for some conditions).  Ken is doing the best work I know of on sweep width for dogs.  I look forward to the paper.

At George Mason University, he added the MapScore project and related work. More generally, he works on evidence and inference with a special interest in causal models, Bayesian networks, and Bayesian search theory, especially the analysis and prediction of lost person behavior. From 2011-2015, Charles led the DAGGRE & SciCast combinatorial prediction market projects at George Mason University, and has recently joined NTVI Federal as a data scientist supporting the Defense Suicide Prevention Office. Charles received a Dual Ph.D. in History & Philosophy of Science and Cognitive Science from Indiana University, followed by a postdoc in machine learning at Monash.
