  1. Columbia UniversityDepartment 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 • 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 email 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
