Robust and structural sparsity auto-encoder with L21-norm minimization

Neurocomputing, 2021
Abstract The mean square error (MSE), as the most commonly used cost function for auto-encoder, is sensitive to outliers or impulsive noises in real-world application, which may misguide the training process. At the same time, stacked auto-encoder(SAE) is indeed a totally fully connected network, the parameters exponentially increase as the nodes and

The in vitro immunomodulatory effect of extracellular products (ECPs) of Vagococcus fluvialis L21 on European sea bass (Dicentrarchus labrax) leucocytes

Fish and Shellfish Immunology, 2015
The immune associated genes, interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor-alpha (TNF-alpha), ciclo-oxigenase-2 (COX-2), and Mx gene were studied by real-time PCR in head-kidney leucocytes of sea bass

The primary structure of rat ribosomal protein L21

Biochemical and Biophysical Research Communications, 1989
The covalent structure of rat ribosomal protein L21 was deduced from the sequence of nucleotides in a recombinant cDNA and confirmed from the NH2-terminal amino acid sequence of the protein. Ribosomal protein L21 contains 159 amino acids (the NH2-terminal methionine is removed after translation of the mRNA) and has a molecular weight of 18,322 ...

Hierarchical extreme learning machine with L21-norm loss and regularization

International Journal of Machine Learning and Cybernetics, 2020
Recently, multilayer extreme learning machine (ELM) algorithms have been extensively studied for hierarchical abstract representation learning in the ELM community. In this paper, we investigate the specific combination of $$L_{21}$$ -norm based loss ...

Optimization of a growth medium using a statistical approach for the production of an alkaline protease from a newly isolated Bacillus sp. L21 [PDF]

Process Biochemistry, 2006
Bacillus sp. L21 was isolated from the by-products of a leather factory (located in Izmir, Turkey) working under extreme alkaline conditions. Its phenotypic and genotypic identifications were completed, and determined as a potential alkaline protease ...

L21 Structure of the Alloy AuAgZn2

Nature, 1963
PROBABLY the most interesting examples of the L21 structure are the copper-based Heusler alloys Cu2MnX (X = aluminium, indium or tin), which are ferromagnetic in the ordered state. Recent additions to this structural type are Cu2MnSb (ref. 1), which is antiferromagnetic, and Au2MnAl (ref. 2), which is ferromagnetic.

Robust nonnegative matrix factorization using L21-norm

Proceedings of the 20th ACM international conference on Information and knowledge management, 2011
Nonnegative matrix factorization (NMF) is widely used in data mining and machine learning fields. However, many data contain noises and outliers. Thus a robust version of NMF is needed. In this paper, we propose a robust formulation of NMF using L21 norm loss function. We also derive a computational algorithm with rigorous convergence analysis.

Deformation of single crystals of the L21 ordered Ag2MgZn

Journal of Materials Science, 1980
The orientation and temperature dependence of slip geometry and yield stress in single crystals of the L21 ordered Ag2MgZn has been studied in compression in the temperature range 290 to 580 K. The slip direction in Ag2MgZn is exclusively 〈1 1 1〉 in this temperature range, but the slip plane varies with crystal orientations; slip occurs on (¯2 1 1) for

B2+L21 ordering in Co2MnAl Heusler alloy

AIP Conference Proceedings, 2014
Magnetic and structural properties of B2 ordered Co2MnAl Heusler alloy have been studied by X-ray diffraction and DC magnetization techniques. X-ray diffractogram shows the structure is of B2 type with preferential site disorder between Mn and Al atoms and presence of a small L21 phase.
