Feature selection for high-dimensional data: a fast correlation-based filter solution
- In: Proceedings of the 20th International Conferences on Machine Learning
, 2003
"... Feature selection, as a preprocessing step to machine learning, is effective in reducing di-mensionality, removing irrelevant data, in-creasing learning accuracy, and improving result comprehensibility. However, the re-cent increase of dimensionality of data poses a severe challenge to many existing ..."

D.: Parallel tracking and mapping on a camera phone
- In Proc. Eigth IEEE and ACM International Symposium on Mixed and Augmented Reality (ISMAR’09) (2009
"... Camera phones are a promising platform for hand-held augmented reality. As their computational resources grow, they are becom-ing increasingly suitable for visual tracking tasks. At the same time, they still offer considerable challenges: Their cameras offer a narrow field-of-view not best suitable ..."

G). We describe a series of adaptations to the Par-allel Tracking and Mapping system to mitigate the impact of the device’s imaging deficiencies. Early results demonstrate a system capable of generating and augmenting small maps, albeit with re-duced accuracy and robustness compared to SLAM on a PC
Improving the Accuracy of Oracle Verdicts Through Automated Model Steering∗
"... The oracle—a judge of the correctness of the system under test (SUT)—is a major component of the testing process. Specifying test oracles is challenging for some domains, such as real-time em-bedded systems, where small changes in timing or sensory input may cause large behavioral differences. Model ..."

behavior may fail to match an acceptable behavior of the SUT, leading to many false positives reported by the oracle. We propose an automated steering framework that can adjust the behavior of the model to better match the behavior of the SUT to re-duce the rate of false positives. This model steering
Forecasting Accuracy and Estimation Uncertainty using VAR Models with Short- and Long-Term Economic Restrictions: A Monte-Carlo Study∗
, 2005
"... Using vector autoregressive (VAR) models and Monte-Carlo simulation methods we investigate the potential gains for forecasting accuracy and estimation uncertainty of two commonly used restrictions arising from economic relationships. The first re-duces parameter space by imposing long-term restricti ..."

On the Use of Bandpass Liftering in Speech Recognition
- IEEE Transactions on Acoustics. Speech and Signal Processing
, 1987
"... Alstract-In a template-based speech recognition system, distortion measures that compute the distance or dissimilarity between two spec-tral representations have a strong influence on the performance of the recognizer. Accordingly, extensive comparative studies have been con-ducted to determine go ..."

We have found that these undesirable spectral measurement variations can be partially controlled (i.e., re-duced in the level of variation) by appropriate signal
On the convergence and accuracy o f homogeneous difference V v schemes fo r one-dimensionai and higher-dimensional parabolic equations

, 1962
"... Homogeneous difference schemes, the general definition of which is given in [I], were considered from the point of view of their application to equations of the parabolic type with one space variable in [21-151. Since the problem of the convergence of difference schemes can be re-duced to the proble ..."

E.: Evolutionary concept learning
- In: GECCO 2002: Proceedings of the Genetic and Evolutionary Computation Conference
, 2002
"... Inductive learning in First-Order Logic (FOL) is a hard task due to both the pro-hibitive size of the search space and the computational cost of evaluating hypotheses. This paper introduces an evolutionary algo-rithm for concept learning in (a fragment of) FOL. The algorithm evolves a population of ..."

Laguerre-SVD reduced-order modeling
- IEEE Trans. Microw. Theory Tech
, 2000
"... Abstract—A reduced-order modeling method based on a system description in terms of orthonormal Laguerre functions, together with a Krylov subspace decomposition technique is presented. The link with Padé approximation, the block Arnoldi process and sin-gular value decomposition (SVD) leads to a simp ..."

Novel features of the approach in-clude the determination of the Laguerre parameter as a function of bandwidth and testing the accuracy of the results in terms of both amplitude and phase.

A method of redundant clocking detection and power reduction at RT level design

"... This paper proposes a novel method to estimate and to re-duce redundant power of synchronous circuits at RT level design. Because much redundant power is caused by redun-dant clockings which activate registers unnecessarily, we de-tect these clockings. They are detected from the difference of the nu ..."
