Marginalizing Corrupted Features
The goal of machine learning is to develop predictors that generalize well to test data. Ideally, this is achieved by training on an almost infinitely large training data set that captures all variations in the data distribution. In practical learning settings, however, we do not have infinite data and our predictors may overfit. Overfitting may be combatted, for example, by adding a regularize...
متن کاملText Retrieval through Corrupted Queries
Our work relies on the design and evaluation of experimental information retrieval systems able to cope with textual misspellings in queries. In contrast to previous proposals, commonly based on the consideration of spelling correction strategies and a word language model, we also report on the use of character n-grams as indexing support.
متن کاملCompressed sensing with corrupted observations
We proposed a weighted l minimization: min , ‖x‖ + λ‖f‖ s.t.Ax+ f= b to recover a sparse vector x and the corrupted noise vector f from a linear measurement b = Ax + f when the sensing matrix A is an m × n row i.i.d subgaussian matrix. Our first result shows that the recovery is possible when the fraction of corrupted noise is smaller than a positive constant, provided that ‖x‖ ≤ O(n/ln (n/‖x ∗...
متن کاملCapacity Bounds for Power- and Band-Limited Wireless Infrared Channels Corrupted by Gaussian Noise
This paper finds asymptotically exact upper and lower bounds on the channel capacity of power and band-limited optical intensity channels corrupted by white Gaussian noise. This work differs from the oft investigated case of the Poisson photon counting channel in that not only are rectangular pulse amplitude schemes considered, but results for more general time-disjoint intensity modulation sch...
متن کاملCorrupted Speech Data Considered Useful
The success of Voice-over-IP technology will crucially depend on the provision of a certain level of perceptual speech quality. In this paper we demonstrate that keeping as much corrupted speech data as possible results in a major step towards this goal. To this end, we explore the combination of two key factors which influence the speech quality as perceived by the user: networking mechanisms ...
