Overview

Our research program aims to lay the foundations for a new systems theory that applies to general controlled information gathering and inference systems with mission planning. Our research approach comprises three inter-related research themes that collectively address the most critical research challenges. These thrusts are:

  1. information-driven structure learning and representation
  2. distributed information fusion
  3. active resource management for effective information exploitation.

We aim to develop an end-to-end framework that will result in better raw sensor data acquisition and processing, improved fusion of multiple sources and modalities, and more effective sensor management and control.

Second-year review meeting

Monday, September 9th, 2013
8:30 am - 4:30 pm
Seminar Room, Zahl Building
U.S. Army Research Laboratory
2800 Powder Mill Road, Adelphi MD 20783
ARL visitor pamphlet: .pdf

Non-ARL personnel should arrange invitations for attendance through Dr. Liyi Dai, ARO

Morning of the review:

Visitors budget 30 minutes to get onto base, get badged, and be escorted to the seminar room. Parking at ARL can be challenging, so allowing additional time for this is also advisable. Visitors should try to park in the South Lot. Late arrivals may have to park in K Lot. Visitors must enter through building 205 and report to the badging office. Government issued ID will be required (2 forms of government issued ID required for non-US citizens). This building and the parking lots are labeled 1n the ARL visitors pamphlet. US visitors will be escorted from the badging room to the meeting room in Zahl. Non-US visitors will need to be escorted from the main front gate to parking, badging, and then the meeting room. Visit requests, filed in advance of the meeting, let the front gate guards know the appropriate escorts for the non-US visitors.

Hotels and transportation

Parking information for those with cars:

For those arriving by car from the South, exit the 405 freeway at Wilshire East, then follow Wilshire East to Westwood North, that end into campus. Past the hospitals there is a parking booth in the center divider. Stop there and get a daily permit for $11. Also ask them for a campus map. You will go to Boelter Hall, that is on your right behind the building that carries the sign "Henry Samueli School of Engineering and Applied Science". We will meet in the Rice Conference Room on the 6th floor, south-west corner of the building. For any problems, call Stefano Soatto at (310) 869 2972.

Agenda (Revised):

The formal agenda will start at 8:30AM with overview and presentations from the VoI MURI team. We will break for lunch and posters (presented by MURI-supported students) at around 11:30AM. We will then resume at 1PM with more presentations and wrapup, ending at around 2:30. This will be followed by a government caucus and feedback at around 3:30PM to the MURI team.
