1. Columbia University Department of Computer Science
Henning Schulzrinne
2001 NSF CISE/EIA RI PI’s Workshop

2. Overview and Goals of Grant
Global-scale information storage & access
Identifying & integrating relevant information
Any format & modality
Networking infrastructure

3. CISE Research Thrusts
23 faculty: 20 tenure track + 3 lecturers; ~12 involved in CISE projects, but whole department uses infrastructure
Multimedia Systems
Luis Gravano: hidden web
Steven Feiner: augmented reality
Kathleen McKeown: summarization
Henning Schulzrinne: multimedia protocols
Yechiam Yemini: active networks

4. CISE Research Thrusts Vision and Robotics Computer Systems
Peter Allen: 3D site modeling using robots
John Kender: semantic compression
Shree Nayar: vision sensors
Computer Systems
Steven Nowick: asynchronous digital systems
Databases and Data Mining
Luis Gravano: textual and structured databases
Gail Kaiser: cooperative software engineering
Ken Ross: database query processing
Sal Stolfo: mining-based intrusion detection

5. Infrastructure Equipment
CISE(CUCS) = research groups + infrastructure
Two generations of LANs  100 Mb/s switched for every workstation
CLIC teaching lab (Sun + Linux)
File servers  TB RAID
Compute clusters (Sun  Linux)
SGI Onyx 2 graphics server

6. Columbia CS Lab and Interactive Classroom
About 40 Unix workstations
Combines
MS/PhD research + project lab, with multimedia capabilities
Teaching lab, with TV/Internet video studio for distance learning
Compute cluster

7. CLIC

8. CLIC

9. Experiences with CLIC Works well for recitation sections
Most difficult: making local students feel comfortable
Faculty focus on camera
Need to repeat student questions
Computers in classroom distinctively mixed blessing  compete with and web

10. CISE infrastructure: Staff
Support servers, CLIC, networks
Maintain software infrastructure
Provide training for undergraduates

11. CISE outcomes - Leverage
Encouraged Microsoft equipment gift of $1M for Win2K teaching + project lab
Caused $100k/year from provost’s office
Visibility  school support for 1 FTE
INTEREST networking lab

12. CISE outcome - CLIC Undergraduate research MS students
Multimedia I/O equipment for variety of classes (visual interfaces, adv. Internet services, operating systems, …)
Local control of software and hardware infrastructure vital for non-standard projects and courses
Better ability to teach programming recitations

13. MAGIC: Multimedia Abstract Generation for Intensive Care
Voice: Ms. Jones is an 80 year old, diabetic, hypertensive, female patient of Dr. Smith undergoing CABG

14. Recovering 3D Models of Urban Structures

15. Success + Failure
Wide variety of research results, from media acquisition, to transport/communication, to content generation and processing
Integration across research efforts difficult, since research part of many NSF/DARPA/industrial projects

16. More or Different Resources
More staff support
Need cross-project programming and system support
Cost of equipment , cost of staff 
Plan for equipment lifetime of 3 years
