Bayesian modelling of music : algorithmic advances and experimental studies of shift-invariant sparse coding [PDF]

open access: yes, 2005
PhDIn order to perform many signal processing tasks such as classification, pattern recognition and coding, it is helpful to specify a signal model in terms of meaningful signal structures.

Sparse-PE: A Performance-Efficient Processing Engine Core for Sparse Convolutional Neural Networks

open access: yesIEEE Access, 2021
Sparse convolutional neural network (CNN) models reduce the massive compute and memory bandwidth requirements inherently present in dense CNNs without a significant loss in accuracy. Sparse CNNs, however, present their own set of challenges including non-

Frame coherence and sparse signal processing [PDF]

open access: yes2011 IEEE International Symposium on Information Theory Proceedings, 2011
The sparse signal processing literature often uses random sensing matrices to obtain performance guarantees. Unfortunately, in the real world, sensing matrices do not always come from random processes. It is therefore desirable to evaluate whether an arbitrary matrix, or frame, is suitable for sensing sparse signals.

Sparse multiscale gaussian process regression [PDF]

open access: yesProceedings of the 25th international conference on Machine learning - ICML '08, 2008
Most existing sparse Gaussian process (g.p.) models seek computational advantages by basing their computations on a set of m basis functions that are the covariance function of the g.p. with one of its two inputs fixed. We generalise this for the case of Gaussian covariance function, by basing our computations on m Gaussian basis functions with ...

New Directions In Sparse Sampling and Estimation For Underdetermined Systems [PDF]

open access: yes, 2013
A central objective in signal processing is to infer meaningful information from a set of measurements or data. While most signal models have an overdetermined structure (the number of unknowns less than the number of equations), traditionally very few ...

Explicit Object Representation by Sparse Neural Codes [PDF]

open access: yes, 2008
Neurons have been identified in the human medial temporal lobe (MTL) that display a strong selectivity for only a few stimuli (such as familiar individuals or landmark buildings) out of perhaps 100 presented to the test subject.
