The phrase "a sparse representation from" is correct and usable in written English.
It can be used in contexts related to data analysis, machine learning, or signal processing where one is discussing the extraction or derivation of a simplified or reduced form of data.
Example: "The algorithm generates a sparse representation from the original dataset, allowing for more efficient processing."
Alternatives: "a sparse representation of" or "a sparse model derived from".
For suitable inputs, a sparse representation for 𝔼 decreases the memory requirement considerably.
In this paper, we propose a novel scheme for palmprint recognition using a sparse representation of features obtained from Bank of Binarized Statistical Image Features (B-BSIF).
A sparse representation of face is learned from video for online face recognition under unconstrained conditions [31].
Unlike the science professoriate, Goldin and Katz show, in recent decades the well-paid pharmacy field has moved from a sparse representation of women to a rapidly growing female majority.
The basic idea is to cast recognition as a sparse representation problem, utilizing new mathematical tools from compressed sensing and L1 minimization.
Besides the Dirac dictionary, other three sparse dictionaries including Db6 wavelets, Sym4 wavelets and cubic B-spline functions can also accurately identify both the single and double impact forces from highly noisy responses in a sparse representation frame.
In particular, the paper will focus on a recently proposed face recognition algorithm, where a sparse representation framework has been used to recover human identities from facial images that may be affected by illumination, occlusion, and facial disguise.
In Section 2, the transform from a DOA estimation problem to a sparse representation problem is briefly presented.
If a signal is known to have a sparse representation with respect to a frame, it can be estimated from a noise-corrupted observation by finding the best sparse approximation to.
First, a sparse representation (SR) mathematical model for sparse blade tip-timing signals is built.
