Overview and Goals of Grant
Global-scale information storage & accessIdentifying & integrating relevant informationAny format & modalityNetworking infrastructure

CISE Research Thrusts
23 faculty: 20 tenure track + 3 lecturers; ~12 involved in CISE projects, but whole department uses infrastructureMultimedia SystemsLuis Gravano: hidden webSteven Feiner: augmented realityKathleen McKeown: summarizationHenning Schulzrinne: multimedia protocolsYechiam Yemini: active networks

CISE Research Thrusts
Vision and RoboticsPeter Allen: 3D site modeling using robotsJohn Kender: semantic compressionShree Nayar: vision sensorsComputer SystemsSteven Nowick: asynchronous digital systemsDatabases and Data MiningLuis Gravano: textual and structured databasesGail Kaiser: cooperative software engineeringKen Ross: database query processingSal Stolfo: mining-based intrusion detection

Infrastructure Equipment
CISE(CUCS) = research groups + infrastructureTwo generations of LANs 100 Mb/s switched for every workstationCLIC teaching lab (Sun + Linux)File servers TB RAIDCompute clusters (Sun Linux)SGI Onyx 2 graphics server

Columbia CS Lab and Interactive Classroom
About 40 Unix workstationsCombinesMS/PhD research + project lab, with multimedia capabilitiesTeaching lab, with TV/Internet video studio for distance learningCompute cluster

CLIC

CLIC

Experiences with CLIC
Works well for recitation sectionsMost difficult: making local students feel comfortableFaculty focus on cameraNeed to repeat student questionsComputers in classroom distinctively mixed blessing compete with email and web

CISE infrastructure: Staff
Support servers, CLIC, networksMaintain software infrastructureProvide training for undergraduates

CISE outcomes - Leverage
Encouraged Microsoft equipment gift of $1M for Win2K teaching + project labCaused $100k/year from provosts officeVisibility school support for 1 FTEINTEREST networking lab

CISE outcome - CLIC
Undergraduate researchMS studentsMultimedia 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 coursesBetter ability to teach programming recitations

MAGIC: Multimedia Abstract Generation for Intensive Care

Recovering 3D Models of Urban Structures

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

More or Different Resources
More staff supportNeed cross-project programming and system supportCost of equipment , cost of staff Plan for equipment lifetime of 3 years
