This course will cover recent developments in randomized matrix algorithms of interest in large-scale machine learning and statistical data analysis applications. By this, we will mean basic algorithms for fundamental matrix problems—such as matrix multiplication, least-squares regression, lowrank matrix approximation, and so on—that use randomization in some nontrivial way. This area goes by t...

aBstract Mobile user data mining is about extracting knowledge from raw data collected from mobile users. There have been a few approaches developed, such as frequency pattern and location dependent mobile user data mining (Goh & Taniar, 2004). Previously proposed methods share the common drawbacks of costly resources that have to be spent in identifying the location of the mobile node and cons...

A novel composite right/left handed transmission line (CRLH TL) is proposed, for the first time using the Wunderlich-shaped dentiform capacitor and meandered-line short-circuited stub inductor (SSI). The CRLH TL features a larger value of CL and in turn a lower resonance relative to the previous one employing an interdigital capacitor and an SSI. The unique feature of the CRLH TL is applied to ...

In this work, we propose a dual-network integrated logistic matrix factorization (DNILMF) algorithm to predict potential drug-target interactions (DTI). The prediction procedure consists of four steps: (1) inferring new drug/target profiles and constructing profile kernel matrix; (2) diffusing drug profile kernel matrix with drug structure kernel matrix; (3) diffusing target profile kernel matr...

Tissue engineering appears promising as an alternative technique for esophageal replacement. Mesenchymal stem cells (MSCs) could be of interest for esophageal regeneration. Evaluation of the ability of an acellular matrix seeded with autologous MSCs to promote tissue remodeling toward an esophageal phenotype after circumferential replacement of the esophagus in a mini pig model. A 3 cm long cir...

I consider a lattice model of a gauge field interacting with matrixvalued scalars in D dimensions. The model includes an adjustable parameter σ, which plays role of the string tension. In the limit σ = ∞ the model coincides with Kazakov-Migdal’s “induced QCD”, where Wilson loops obey a zero area law. The limit σ = 0, where Wilson loops W (C) = 1 independently of the size of the loop, correspond...

The metropolitan dynamics typology of the Portuguese urban system is the product of a methodology based on Geographic Information Systems (GIS). A GIS data describes six dimensions of metropolisation (population, economy, urban organisation, society and culture, networks and territorial organisation), based on a matrix of entities or indicators. Such a matrix has been subjected to treatment by ...

Ghulam Murtaza, Nassar Ikram 1,2 National University of Sciences and Technology, Pakistan [email protected] [email protected] Abstract. An MDS matrix is an important building block adopted by different algorithms that provides diffusion and therefore, has been an area of active research. In this paper, we present an idea of direct exponent and direct square of a matrix. We prove...

We survey currently available algorithms for computing with matrix groups over infinite domains. We discuss open problems in the area, and avenues for further development.
