Tiled QR factorization algorithms [PDF]

open access: yes, 2011
This work revisits existing algorithms for the QR factorization of rectangular matrices composed of p-by-q tiles, where p >= q. Within this framework, we study the critical paths and performance of algorithms such as Sameh and Kuck, Modi and Clarke ...

Unit, Irreducible, and Prime Elements of The Integral Domain Z[sqrt (5)]

open access: yesJurnal Matematika
In abstract algebra at the undergraduate level, the ring Z[sqrt(5)] is often used as a simple example of an integral domain that does not satisfy the unique factorization domain (UFD) but Z[sqrt(5)] is Halfway Factorial Domain (HFD).

Scalable and interpretable product recommendations via overlapping co-clustering

open access: yes, 2017
We consider the problem of generating interpretable recommendations by identifying overlapping co-clusters of clients and products, based only on positive or implicit feedback.

Consideration of analogies between magnetic and quantum notices for molecular network

open access: yesITM Web of Conferences, 2018
Magnetic properties of spin glass materials [9,13] are close to quantum interpretation in their nature description [17]. Therefore, we can look for possible kinds of analogies in process of defining theoretic and practice conventions, rules and ...

Non-unique factorization of polynomials over residue class rings of the integers

open access: yes, 2011
We investigate non-unique factorization of polynomials in Z_{p^n}[x] into irreducibles. As a Noetherian ring whose zero-divisors are contained in the Jacobson radical, Z_{p^n}[x] is atomic.

A musculoskeletal model of human locomotion driven by a low dimensional set of impulsive excitation primitives

open access: yesFrontiers in Computational Neuroscience, 2013
Human locomotion has been described as being generated by an impulsive (burst-like) excitation of groups of musculotendon units, with timing dependent on the biomechanical goal of the task. Despite this view is supported by many experimental observations

Inverse-Free Incremental Learning Algorithms With Reduced Complexity for Regularized Extreme Learning Machine

open access: yesIEEE Access, 2020
The existing inverse-free incremental learning algorithm for the regularized extreme learning machine (ELM) was based on an inverse-free algorithm to update the regularized pseudo-inverse, which was deduced from an inverse-free recursive algorithm to ...

Sparse Matrix Factorization [PDF]

open access: yes, 2014
We investigate the problem of factorizing a matrix into several sparse matrices and propose an algorithm for this under randomness and sparsity assumptions.
