Sparse coding models can exhibit decreasing sparseness while learning sparse codes for natural images. [PDF]

open access: yesPLoS Computational Biology, 2013
The sparse coding hypothesis has enjoyed much success in predicting response properties of simple cells in primary visual cortex (V1) based solely on the statistics of natural scenes. In typical sparse coding models, model neuron activities and receptive

Generalized sparse codes for non-Gaussian channels: Code design, algorithms, and applications [PDF]

open access: yesFundamental Research, 2022
In this paper, generalized sparse (GS) codes are proposed to support reliable and efficient transmission over non-Gaussian channels. Specifically, by expanding the single-parity check (SPC) code constraints with powerful algebraic codes, GS codes ...

Semi-Supervised Sparse Coding [PDF]

open access: yes2014 International Joint Conference on Neural Networks (IJCNN), 2015
Sparse coding approximates the data sample as a sparse linear combination of some basic codewords and uses the sparse codes as new presentations. In this paper, we investigate learning discriminative sparse codes by sparse coding in a semi-supervised ...

Learning dictionaries of sparse codes of 3D movements of body joints for real-time human activity understanding. [PDF]

open access: yesPLoS ONE, 2014
Real-time human activity recognition is essential for human-robot interactions for assisted healthy independent living. Most previous work in this area is performed on traditional two-dimensional (2D) videos and both global and local methods have been ...

Neuronal allocation and sparse coding of episodic memories in the human hippocampus [PDF]

open access: yesScientific Reports
Neurocomputational models hold that individual episodic memories are represented by a sparse, pattern-separated coding scheme in the hippocampus. Animal studies further suggest that the allocation of neurons to such codes is non-random and may be biased ...

Finite-rate sparse quantum codes aplenty [PDF]

open access: yesQuantum, 2023
We introduce a methodology for generating random multi-qubit stabilizer codes based on solving a constraint satisfaction problem (CSP) on random bipartite graphs.
