Some Older Projects

Extraction and Interpretation of Information from Large-Scale Hyperspectral Data for Mapping and Monitoring Wetland Ecosystems (NSF)

Versatile Co-cluster Analysis for Bi-modal and Multi-modal Data (NSF)

Scalable Clustering of Complex Data Types (NSF)

A Study of Potential Techniques for Labelling Hierarchically Organized Web-pages (Yahoo!)

Gene Network Discovery (NSF)

Pervasive Personalization (Intel)

Agents that work on a user's behalf at all touch-points - including wireless devices - through which s/he interacts with the web, and provide a range of personalized services that are location, time and device format sensitive. In addition to Intel's grant, we gratefully acknowledge their donation of two workstations, valued at about $8K, to our lab.

Web Mining (supported by Intel, IBM, Neonyoyo/Interwoven, Accenture,

Analysis of web content (text and tags), hyperlink structure and usage of web sites to better customize such sites to the needs of site-visitors. E-commerce applications. Relating web analytics to system performance/availability.

Active Stereoscopic Visual Search (NSF)

Intrusion Detection, Network Management (Tivoli)

Detecting and modeling change/deviations that may indicate computer security/integrity problems.

Approximate Attribute Matching (HNC Software)

Finding similarities between XML documents, or between an XML query and a document.

Data Mining (Dell and KD1 (now part of NetPerceptions) )

Identifying and extracting useful information from reams of data and thus facilitate smart business decisions. Applications to the computer industry and e-commerce.

Multi-learner and Hybrid Intelligent Systems (funded by ARO, NSF).

Ensemble and hybrid networks; modular approaches for non-stationary problems; multi-classifier systems; combining connectionist and symbolic techniques; applications to difficult object recognition problems. Part of Center for Imaging Science, a joint effort with Washington U., Harvard and MIT.

Web Usage Analysis, User Profiling, Knowledge transfer and reuse (NSF)

Analyzing web logs, click-stream analysis, web metrics, recommender systems. Use of knowledge developed in previous tasks to help in a new task. Design of next-generation collaborative filters.

Modeling and Identification of Interacting Objects (Raytheon)

A spatio-temporal problem in which the sequence of symbols emitted by an object may be affected by others in the vicinity.

Model Interpretation and Visualization

How can we understand what a neural network does? Rule extraction from neural networks; theory refinement; visualization of network structure and behavior; non-linear methods for dimensionality reduction. Online Demo of Radial Basis Function Network Toolkit

Classification and Clustering of Hyperspectral Data (NASA)

Working in high-dimensions; identifying land cover types from aerial images.

Robust Neural Networks and Pose Estimation (Phillips Lab)

Techniques for identifying outliers and atypical data, and for adapting to dynamic environments. Pose estimation of space objects from image sequences.

Autonomous Intelligent Machines (TATP)

Particularly for navigating in hazardous environments and detection environmental hazards.

Identification and Classification of spatio-temporal sequences (NSF/ONR / Tracor)

Dynamic networks are being studied that make occasional judgements on input sequences, and cater to time alignment and dynamic time warping problems. Applied to short-duration underwater signals. A non-linear memory structure based on habituation has been developed that has powerful approximation capabilities.

Semiconductor Manufacturing (Motorola).

Modeling of various semiconductor manufacturing processes, and prediction of chip quality.

Comparative performance of Static Classifiers (DARPA/ONR/Tracor)

This study includes practical techniques and theoretical studies on network growth/pruning for valid generalization, study of noise sensitivity of different networks, and performance on limited, high dimensional inputs. Our techniques have been successfully applied to sonar and radar data, and for identification of defects in manufacturing problems.

Forecasting/Prediction (Schlumberger)

Adaptive, non-linear regression techniques for forecasting desired response given correlated parameters. Prediction of (chaotic) time series from past samples. Applied to logging data from Schlumberger.

Data Mining of Student Records (UT)
