Distributed pattern detection in cyber networks

Distributed pattern detection in cyber networks

Conference on Cyber Sensing

作者： Paffenroth, Randy C. Du Toit, Philip C. Scharf, Louis L. Jayasumana, Anura P. Banadara, Vidarshana W. Nong, Ryan Numerica Corp Loveland CO USA Colorado State Univ Ft Collins CO 80523 USA

In this paper we describe an approach for the detection and classification of weak, distributed patterns in sensor networks. Of course, before one can begin development of a pattern detection algorithm, one must first define the term "pattern", which by nature is a broad and inclusive term. One of the key aspects of our work is a definition of pattern that has already proven effective in detecting anomalies in real world data. While designing detection algorithms for all classes of patterns in all types of networks sounds appealing, this approach would almost certainly require heuristic methods and only cursory statements of performance. Rather, we have specifically studied the problem of intrusion detection in computer networks in which a pattern is an abnormal or unexpected spatio-temporal dependence in the data collected across the nodes. We do not attempt to match an a priori template, but instead have developed algorithms that allow the pattern to reveal itself in the data by way of dependence or independence of observed time series. Although the problem is complex and challenging, recent advances in l(1) techniques for robust matrix completion, compressed sensing, and correlation detection provide promising opportunities for progress. Our key contribution to this body of work is the development of methods that make an accounting of uncertainty in the measurements on which the inferences are based. The performance of our methods will be demonstrated on real world data, including measured data from the Abilene Internet2 network.

Attempts to recover images from objects which diffuse radiation pose an especially challenging problem in terms of defining a suitable reconstruction algorithm and with regard to identifying an appropriate computing environment for efficient processing. In this paper we consider both issues and, in particular, describe results of an algebraic technique for imaging the interior of objects which diffuse penetrating radiation using a new multicomputer environment. Two important issues which arise when considering the numerical solution of ultra large problems are the numerical precision achieved and the overall computing efficiency. Our interest in this problem concerns the possibility of obtaining 3-D optical images of tissue which could identify the availability of oxygen by evaluating oxygen- dependent changes in the near infrared spectrum of hemoglobin. These studies were motivated by recent reports from our group and others, which showed promising results for imaging in dense scattering media given only diffusely scattered signals. In our model we assume the use of an NIR laser to provide the input radiation and suitable detectors to measure both transmission and backscatter. In our present work we assume a simple Markov process model for the way in which the energy travels in the medium, but it should be noted that the reconstruction technique we propose can use any model, including nonlinear as well as linear effects, and higher order processes. Current simulations are in 2-D but the methods are easily extended to 3-D. The algorithms we propose are more closely related to algebraic reconstruction algorithms such as ART, SIRT, and SART than to algorithms based on the Born and Rytov approximations such as used for tomographic imaging with diffracting sources. Our algorithms are a significant departure from those based on these standard algebraic methods. We assume only a probabilistic knowledge of the path of the radiation, and minimal knowledge of the absorption

Vision Geometry IV Conference

A hierarchical scheme for chain encoded digital contours is introduced. If the contour represents the boundary of a binary image, a true digitization of the image is realized as the pyramid structure goes from the fine to coarser resolution levels. A progressive transmission system is designed to go from a coarse resolution level to finer levels which uses essentially the same number of bits as transmission of the contour at the finest resolution.

7TH ANNUAL CONF ON INTEGRATED CIRCUIT METROLOGY, INSPECTION, AND PROCESS CONTROL

ISBN: (纸本)0819411604

For achieving more accurate overlay measurement of optical metrology system, this paper shows a new approach from the viewpoint of measured data correlation between before and after etching. From this comparison, two new methodologies are proposed. One method does not require measurement after etching to optimize measurement algorithms. The superiority of this approach is also discussed compared to the criteria of measurement repeatability and TIS. Using the new methodologies, measurement algorithms are optimized for many kinds of processed wafers, including high temperature sputtered aluminum, with a grainier surface than conventionally sputtered aluminum.

In this paper, we present an inversion method to enhance a binary decision tree classifier using boundary search of training samples. We want to enhance the training at those points which are close to the boundaries. Selection of these points is based on the Euclidean distance from those centroids close to classification boundaries. The enhanced training using these selected data was compared with training using randomly selected samples. We also applied this method to improve the classification of pap smear screening data.

This paper presents various architectural options for implementing a K-Means Re-Clustering algorithm suitable for unsupervised segmentation of hyperspectral images. Performance metrics are developed based upon quantitative comparisons of convergence rates and segmentation quality. A methodology for making these comparisons is developed and used to establish K values that produce the best segmentations with minimal processing requirements. Convergence rates depend on the initial choice of cluster centers. Consequently, this same methodology may be used to evaluate the effectiveness of different initialization techniques.

An exciting possibility for the GLAST main instrument is a scintillating fiber system where the properties of both a tracker and a calorimeter are combined in one type of detector module. This instrument provides all the detector capabilities required to achieve the science goals of the GLAST mission, at a substantially reduced cost compared to the baseline technology, and with the benefit of increased effective area and superior low energy angular resolution.

4TH CONF ON THE SIGNAL AND DATA PROCESSING OF SMALL TARGETS 1992

ISBN: (纸本)0819408638

The central problem in multitarget-multisensor tracking is the data association problem of partitioning the observations into tracks and false alarms so that an accurate estimate of the true tracks can be recovered. Many previous and current methodologies are based on single scan processing, which is real-time, but often leads to a large number of partial and incorrect assignments, and thus incorrect track identification. The fundamental difficulty with this approach is that there is simply not enough information in single scan processing to properly partition the observations into tracks and false alarms. In this work we formulate the problem of data association for track initiation and extension using multiscan windows in order to obtain superior track identification. A model problem is investigated to show the effect of window size, probability of detection, probability of false alarms, and measurement error on solution quality and timings.

A least-squares algorithm developed for analysis of fast-neutron transmission data resulting from non-destructive interrogation of sealed luggage and containers is subjected to a probabilistic interpretation. The approach is to convert knowledge of uncertainties in the derived areal elemental densities, as provided by this algorithm, into probability information that can be used to judge whether an interrogated object is either benign or potentially contains an illicit substance that should be investigated further. Two approaches are considered in this paper. One involves integration of a normalized probability density function associated with the least-squares solution. The other tests this solution against a hypothesis that the interrogated object indeed contains illicit material. This is accomplished by an application of the F-distribution from statistics. These two methods of data interpretation are applied to specific sets of neutron transmission results produced by Monte Carlo simulation.

A fully optimized computer-aided diagnosis (CAD) system using system-oriented optimization algorithm has been developed for mass detection in digital mammography for the improvement of CAD performance on sensitivity and specificity. Based on a series of developed adaptive modules, simulated annealing (SA) algorithm is employed on CAD system optimization that is a typical combinatorial mixed-discrete optimization problem. The CAD system is optimized on a training database and evaluated through a test database, the cases in both databases are biopsy proven and selected by experienced radiologists. Both optimized and corresponding un-optimized CAD system have been evaluated using the same test database to compare the system performance. Obvious performance improvement has been obtained on optimized system. The results express the effectiveness of the method developed in this paper.
