Generalized Alpha-Beta Divergences and Their Application to Robust Nonnegative Matrix Factorization

Entropy, 2011
We propose a class of multiplicative algorithms for Nonnegative Matrix Factorization (NMF) which are robust with respect to noise and outliers. To achieve this, we formulate a new family generalized divergences referred to as the Alpha-Beta-divergences ...

Stage‐Specific Indicators of Northern Yellowtail Rockfish (Sebastes flavidus) Recruitment in the California Current Ecosystem

Fisheries Oceanography, EarlyView.
ABSTRACT Oceanographic and ecological conditions can be used to inform forecasts and decision‐making for marine resources, but the dominant drivers of recruitment variability remain poorly understood for many fish stocks. We developed a conceptual life‐history model of the oceanographic and ecological variables that influence the recruitment of ...

Clinicopathological and transcriptomic profiles of 101 patients with diffuse large B‐cell lymphoma/high‐grade B‐cell lymphoma with double‐hit MYC and BCL2 or BCL6 and triple hit

Histopathology, EarlyView.
Diffuse large B‐cell lymphoma/high‐grade B‐cell lymphoma (DLBCL/HGBCL) is a mature aggressive B‐cell lymphoma. This article performed a comprehensive clinicopathological and transcriptomic analyses of this lymphoma category. Aims Diffuse large B‐cell lymphoma/high‐grade B‐cell lymphoma (DLBCL/HGBCL) with MYC and BCL2 rearrangements (double‐hit lymphoma

Graph Regularized Non-negative Matrix Factorization By Maximizing Correntropy

, 2014
Non-negative matrix factorization (NMF) has proved effective in many clustering and classification tasks. The classic ways to measure the errors between the original and the reconstructed matrix are $l_2$ distance or Kullback-Leibler (KL) divergence ...

Penetration enhancement effects of topically applied crosslinked hyaluronic acid

International Journal of Cosmetic Science, EarlyView.
Cross‐linked hyaluronic acid (HA) was demonstrated to enhance the topical delivery of a variety of hydrophilic actives into the skin. This phenomenon was observed for both small molecules and macromolecules, the latter of which was analysed with MALDI mass spectrometry imaging (MALDI‐MSI).

Postoperative Pain After Endodontic Treatment in HIV‐Positive Patients Under HAART: A Prospective Observational Cohort Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim To compare post‐operative pain following root canal treatment (RCT) in HIV‐positive patients receiving highly active antiretroviral therapy (HAART) and HIV‐negative patients and to assess the influence of systemic condition on endodontic pain.

Sequential Sparse NMF

, 2011
Nonnegative Matrix Factorization (NMF) is a standard tool for data analysis. An important variant is the Sparse NMF problem. A natural measure of sparsity is the L₀ norm, however its optimization is NP-hard. Here, we consider a sparsity measure linear in the ratio of the L₁ and L₂ norms, and propose an efficient algorithm to handle the norm ...

Approximate Nonnegative Matrix Factorization via Alternating Minimization

, 2004
In this paper we consider the Nonnegative Matrix Factorization (NMF) problem: given an (elementwise) nonnegative matrix $V \in \R_+^{m\times n}$ find, for assigned $k$, nonnegative matrices $W\in\R_+^{m\times k}$ and $H\in\R_+^{k\times n}$ such that $V ...

Use of Cluster Analysis for Identifying Metafounders

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ$$ \boldsymbol{\Gamma} $$ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A$$ \mathbf{A} $$, creating matrix AΓ$$ {\mathbf{A}}^{\boldsymbol{\Gamma}} $$.

Biomarkers for therapeutic response and adverse outcomes in atopic dermatitis: A systematic review

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This review assessed 52 biomarkers predicting systemic therapy response and adverse events in atopic dermatitis. Most studies focused on dupilumab, and findings were inconsistent. IgE and eosinophils were largely non‐predictive, though elevated eosinophils and LDH sometimes indicated poorer outcomes.
