Topological Analysis of Noisy Data

Topology-based Methods for Analysis and Visualization of Noisy Data
Topological cleanup of nisy data The size of scientific data sets that are generated by evolving supercomputers, large sensor networks, and high-resolution imaging devices is increasing rapidly, at an exponential rate. This project addresses the need for more effective data analysis methods. It develops technologies concerned with the analysis and representation of very large scientific data sets, emphasizing concepts that capture qualitative characteristics. In light of the limitations of purely visualization-based approaches applied to "raw" scientific data sets directly, this project aims at devising new concepts for visualizing very large and complex data sets. The methods being developed first extract meaningful qualitative information from a given data set, which is then used to present the higher-level information content of the data set in a significantly more compact form, thus stressing relevant qualitative behavior. The project builds on concepts from classical topology and geometry, which have contributed substantially to the development of the relatively new fields of computational topology and computational geometry. These two fields hold great potential for substantially advancing the visualization technology for understanding extremely large, complicated data sets. This projects adapts (and generalizes) computational topology and computational geometry algorithms that are well-established for smooth mathematical functions to real-world, finite-sample data sets, i.e., functions sampled at a finite number of points (that could possibly be connected by a mesh). Real-world data sets are noisy, which further complicates the application of topological methods that were developed originally for smooth functions. This project investigates the generalization of techniques based on Morse and Morse-Smale theory (studying critical-point behavior and drawing qualitative conclusions about functions) to discretized scalar fields that change over time and also contain noise.

VACET

VACET: Visualization and Analytics Center for Enabling Technologies

This project focuses on leveraging scientific visualization and analytics software technology as an enabling technology for increasing scientific productivity and insight. Advances in computational technology have resulted in an "information big bang," which in turn has created a significant data understanding challenge. This challenge is widely acknowledged to be one of the primary bottlenecks in contemporary science. The vision for our Center is to respond directly to that challenge by adapting, extending, creating when necessary and deploying visualization and data understanding technologies for our science stakeholders. Using an organizational model as a Visualization and Analytics Center for Enabling Technologies (VACET), we are well positioned to be responsive to the needs of a diverse set of scientific stakeholders in a coordinated fashion using a range of visualization, mathematics, statistics, computer and computational science and data management technologies.

Embedded Streaming

Performace and Scalability Study for Streaming Algorithms
ViSUS_on_IPOD. Development of software tools that run on embedded systems involves a number of challenges ranging from porting to specialized processors, running with extremely limited memory, reduced OS support, and dealing with particularly slow and imbalanced hardware performance. We propose a practical study of these challenges with focus on the Progressive Image Analysis and develop and adaptation to devices using an ARM core processor (used in digital cameras, GPS, hand held computers, smartcards, wristwatches, USB hard drives, i-pod, and more) using linux and windows CE operating systems. Our concrete goal is to program an ARM system with 32/64 MB of memory to display in real time gigabytes to terabytes of high resolution satellite imagery and KML vector information. With this focused effort we will (i) produce a prototype tool of practical interest for the geospatial intelligence community and (ii) develop important expertise in formal and practical methods that allow successful development and deployment of software tools for embedded systems that can be used effectively on the field for defense and intelligence operations.

NAPA

NAPA: Novel Architectures and Progressive Algorithms
Topology of water molecules at high pressure. In this project we conduct basic research in progressive algorithms for the real-time analysis of streaming data. The focus is on enabling feature and anomaly detection in massive amounts of image data. The project explores the use of hierarchical data representations and storage layout designs to achieve high performance capabilities. The utility of novel architectures, such as GPU-based clusters and/or cellbased machines, is also explored. We also investigate the support of real-time continuous and ad hoc queries over streaming image data, including the design of dynamic algorithms for query optimization enabling efficient usage of computing and storage resources. The results of this research will be useful to next-generation feature detection software tools for analysis of high resolution satellite imagery of interest to NGA and others.

Morse Theory for Data Understanding

Efficient and Reliable Data Exploration Via Multi-Scale Morse Analysis and Combinatorial Information Visualization
Topology of water molecules at high pressure. In this project we develop a new visualization framework based on the coupling of general-purpose data analysis tools with Information Visualization techniques to allow rapid computation and effective presentation of meta-data road-maps guiding scientists in the exploration through terabytes of raw data. We use Morse theory as the mathematical foundation for the analysis, extracting multi-scale models highlighting fundamental characteristics ubiquitous in scientific data, based on topology. Morse theory can be used in a wide range of applications such as the comparison of simulation results, validation of simulations with experimental data, image segmentation, or reconstruction of structures emerging in simulations from molecular dynamics, material sciences and combustion chemistry. The core of our technology is based on the development of combinatorial algorithms that robustly handle real, sampled data while maintaining the formal guarantees of the underlying mathematics of smooth functions.

ViSUS

ViSUS: Visualization Streams for Ultimate Scalability
In this LDRD project we develop a suite of progressive visualization algorithms and a data-streaming infrastructure that enable interactive exploration of scientific datasets of unprecedented size. The methodology aims to globally optimize the data flow in a pipeline of processing modules. Each module reads a multi-resolution representation of the input while producing a multi-resolution representation of the output. The use of multi-resolution representations provides the necessary flexibility to trade speed for accuracy in the visualization process. Maximum coherency and minimum delay in the data-flow is achieved by extensive use of progressive algorithms that continuously map local geometric updates of the input stream into immediate updates of the output stream. We implement a prototype software infrastructure that demonstrates the flexibility and scalability of this approach by allowing large data visualization on single desktop computers, on PC clusters, and on heterogeneous computing resources distributed over a wide area network. When processing terabytes of scientific data, we have achieved an effective increase in visualization performance of several orders of magnitude in two major settings: (i) interactive visualization on desktop workstations of large datasets that cannot be stored locally; (ii) real-time monitoring of a large scientific simulation with negligible impact on the computing resources available. The ViSUS streaming infrastructure enabled the real-time execution and visualization of the two LLNL simulation codes (Miranda and Raptor) run at Supercomputing 2004 on Blue Gene/L at its presentation as the fastest supercomputer in the world. In addition to SC04, we have run live demonstrations at the IEEE VIS conference and at invited talks at the DOE MICS office, DOE computer graphics forum, UC Riverside, and the University of Maryland. In all cases we have shown the capability to stream and visualize interactively data stored remotely at the San Diego Supercomputing Center or monitor in real-time simulation codes executed on a cluster of PC’s at LLNL.
