Due to the explosion in size and complexity of Big Data, it is increasingly important to be able to solve problems with very large number of features. Classical feature selection procedures involves combinatorial optimization, with computational time increasing exponentially with the number of features. During the last decade, penalized regression has emerged as an attractive alternative for re...

Let $V$ be the weighted projective variety defined by a homogeneous ideal $J$ and $C$ maximal cone in Gr\"obner fan of with $m$ rays. We construct flat family over $\mathbb A^m$ that assembles degenerations associated all faces $C$. This is multi-parameter generalization classical one-parameter degeneration to weight. explain how our can constructed from Kaveh-Manon's recent work on classificat...

automático Simulaciones, Control y Big Data ayudan a explicar el origen del universo en la “máquina de Dios”. Hace 20 años en las afueras de la multicultural ciudad de Ginebra, Suiza, s e c o m e n z ó a d e s a r r o l l a r e l experimento científico más complejo y desafiante construido por el hombre: se busca reproducir las condiciones del universo una milésima de billonésima de segundo lueg...

13700 million years ago in the Big Bang, an immense concentration of energy was transformed into matter within less than a billionth of a second. The temperatures, densities and energies involved were extremely high. According to Einstein’s law E=mc, to create a matter particle of a certain mass (m), you need a corresponding amount of energy (E), with the speed of light (c) defining the exchang...

The complete mitochondrial genome of the big-eye thresher shark was sequenced using a polymerase chain reaction (PCR)-based method. The total length of mitochondrial DNA is 16,719 bp and includes 13 protein-coding genes, 2 ribosomal RNA, 22 transfer RNA genes, 1 replication origin region and 1 control region. The mitochondrial gene arrangement of the big-eye thresher shark is the same as the on...

Data from a cross-sectional sample (N = 601 men and women) and a longitudinal sample (N = 125 women) were used to test hypotheses about the development of Big Five domains and facets from early adulthood through middle age. Analyses of mean-level age trends indicated that overall Agreeableness and Conscientiousness increased with age and that several facets showed distinctive trends that replic...

Consider the maximal operator $$\mathscr{C} f(x) = \sup_{\lambda\in\mathbb{R}}\Big|\sum_{\substack{y\in\mathbb{Z}^n\setminus\{0\}}} f(x-y) e(\lambda |y|^{2d}) K(y)\Big|,\quad (x\in\mathbb{Z}^n),$$ where $d$ is a positive integer, $K$ Calder\'on-Zygmund kernel and $n\ge 1$. This discrete analogue of real-variable studied by Stein Wainger. The nonlinearity phase introduces variety new difficultie...

Big data sizes are constantly increasing. Big data analytics is where advanced analytic techniques are applied on big data sets. Analytics based on large data samples reveals and leverages business change. The popularity of big data analytics platforms, which are often available as open-source, has not remained unnoticed by big companies. Google uses MapReduce for PageRank and inverted indexes....
