Fuzzy extractors: How to generate strong keys from biometrics and other noisy data
, 2008
"... We provide formal definitions and efficient secure techniques for • turning noisy information into keys usable for any cryptographic application, and, in particular, • reliably and securely authenticating biometric data. Our techniques apply not just to biometric information, but to any keying mater ..."

Monotone Smoothing of Noisy Data

RECONSTRUCTION OF DISCONTINUITIES IN NOISY DATA
"... Abstract. One is given noisy data of a discontinuous piecewise-smooth func-tion along with a bound on its second derivative. The locations of the points of discontinuity of f and their jump sizes are not assumed known, but are instead retrieved stably from the noisy data. The novelty of this paper i ..."

Theory Refinement with Noisy Data
, 1992
"... This paper presents a method for revising an approximate domain theory based on noisy data. The basic idea is to avoid making changes to the theory that account for only a small amount of data. This method is implemented in the EITHER propositional Horn-clause theory revision system. The paper prese ..."

REGULARIZED INTERPOLATION FOR NOISY DATA
"... Interpolation is a vital tool in biomedical signal process-ing. Although there exists a substantial literature dedi-cated to noise-free conditions, much less is known in the presence of noise. Here, we document the breakdown of standard interpolation for noisy data and study the per-formance improve ..."

Factorization with Missing and Noisy Data
"... Abstract. Several factorization techniques have been proposed for tack-ling the Structure from Motion problem. Most of them provide a good solution, while the amount of missing data is within an acceptable ra-tio. Focussing on this problem, we propose an incremental multiresolu-tion scheme able to d ..."

to deal with a high rate of missing data, as well as noisy data. It is based on an iterative approach that applies a classical factorization technique in an incrementally reduced space. Information recovered following a coarse-to-fine strategy is used for both, filling in the missing entries of the input
Correcting Noisy Data
- Machine Learning
, 1999
"... Inductive learning aims at constructing a generalized description of a given set of data, so that future similar instances can be clas-sified correctly. The performance on this task depends crucially on the quality of the data. We investigate here an approach to handling noise in the training data b ..."

by iden-tifying possible noisy attributes and/or class in each instance, and replacing such values with more appropriate ones. The resulting data set would preserve much of the original information, but conform more to the ideal noise-free case. A classifier built from this corrected data should have a
Online Learning of Noisy Data
"... Abstract—We study online learning of linear and kernel-based predictors, when individual examples are corrupted by random noise, and both examples and noise type can be chosen adversarially and change over time. We begin with the setting where some auxiliary information on the noise distribution is ..."

is provided, and we wish to learn predictors with respect to the squared loss. Depending on the auxiliary information, we show how one can learn linear and kernel-based predictors, using just 1 or 2 noisy copies of each example. We then turn to discuss a general setting where virtually nothing is known about
limited noisy data
, 2008
"... Determining the number of components in a linear mixture model is a fundamental problem in many scientific fields, including chemometrics and signal processing. In this paper we present a new method to automatically determine the number of components from a limited number of (possibly) high dimensio ..."

The proposed method, based on the eigenvalues of the sample covariance matrix, combines a matrix perturbation approach for the interaction of signal and noise eigenvalues, with recent results from random matrix theory regarding the behavior of noise eigenvalues.
