Smooth compression, Gallager bound and Nonlinear sparse-graph codes
Data compression data smoothness coding
2015/8/21
A data compression scheme is defined to be smooth if its image (the codeword) depends gracefully on the source (the data). Smoothness is a desirable property in many practical contexts, and widely use...
Eigenvectors of data matrices play an important role in many computational problems, ranging from signal processing to machine learning and control. For instance, algorithms that compute positions of ...
GLOBAL UNCERTAINTY IN EPIPOLAR GEOMETRY VIA FULLY AND PARTIALLY DATA-DRIVEN SAMPLING
Relative orientation Stucture from Motion Epipolar Geometry
2015/8/14
In this paper we explore the relative efficiency of various data-driven sampling techniques for estimating the epipolar geometry and its global uncertainty. We explore standard fully data-driven...
Robust Fisher discriminant analysis
Fisher linear sensitive data convex model a numerical example
2015/8/10
Fisher linear discriminant analysis (LDA) can be sensitive to the problem data. Robust Fisher LDA can systematically alleviate the sensitivity problem by explicitly incorporating a model of data uncer...
Tractable fitting with convex polynomials via sum-of-squares
Set data the sum of squares polynomial convex piecewise polynomial piecewise polynomial set
2015/8/10
We consider the problem of fitting given data(u1, y1),...,(um, ym) where ui ∈ Rn and yi ∈ R with a convex polynomial f. A technique to solve this problem using sum of squares polynomials is pres...

detrending !1 regularization Hodrick–Prescott fi ltering piecewise linear fitting sparse signal recovery feature selection time series analysis trend estimation
2015/8/10
The problem of estimating underlying trends in time series data arises in a variety of disciplines. In this paper we propose a variation on Hodrick-Prescott (H-P) filtering, a widely used method for t...
Scalable statistical monitoring of fleet data
Mixed fleet data statistical monitoring data multivariate statistics
2015/8/7
This paper considers the problem of fitting regression models to historical fleet data with mixed effects, which arises in the context of statistical monitoring of data from a fleet (population) of si...
A mathematical model for interpretable clinical decision support with applications in gynecology
Mathematical model for clinical decision making the system evolution the CDS system CD system
2015/8/7
Over time, methods for the development of clinical decision support (CDS) systems have evolved from interpretable and easy-to-use scoring systems to very complex and non-interpretable mathematical mod...
Operator splitting for conic optimization via homogeneous self-dual embedding
Segmentation method multiplier nonzero subspace double lonely computational subspace
2015/8/7
We introduce a first order method for solving very large cone programs to modest accuracy. The method uses an operator splitting method, the alternating directions method of multipliers, to solve the ...
Optimal crowd-powered rating and filtering algorithms
Filtering building materials application system implicit assumptions and limits
2015/8/7
We focus on crowd-powered filtering, i.e., filtering a large set of items using humans. Filtering is one of the most commonly used building blocks in crowdsourcing applications and systems. While solu...
