Proceedings of the ninth ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '03, 2003
Existing association rule mining algorithms suffer from many problems when mining massive transactional datasets. One major problem is the high memory dependency: either the gigantic data structure built is assumed to fit in main memory, or the recursive mining process is too voracious in memory resources. Another major impediment is the repetitive and

INVERTIBLE COMMUTATORS IN MATRIX RINGS
Journal of Algebra and Its Applications, 2011In a matrix ring R = 𝕄2(S) where S is a commutative ring, we study equations of the form XY - YX = U ∈ GL 2(S), focusing on matrices in R that can appear as X or as XY in such equations. These are the completable and the reflectable matrices in R.

The inverted functional matrix
Proceedings of the 33rd annual on Southeast regional conference - ACM-SE 33, 1995The inverted functional matrix provides a new approach to organizing and managing projects in software engineering courses. The model simulates real-world software development and provides meaningful and varied experiences for students. Individual teams are functional units, responsible for different life cycle phases. The Inverted Functional Matrix is

Matrix Inverter: A Multilevel Inverter Based on Matrix Converter Switch Matrix
2020 IEEE Electric Power and Energy Conference (EPEC), 2020This paper presents a new concept of matrix converter application as an inverter. A matrix converter is commonly used as an AC-to-AC conversion device. Hypothetically the AC sources of the matrix converter can be replaced with DC sources. By using a switching strategy similar to a multilevel inverter switching strategy, and some modification on the ...

Inverter matrix for the Clementine mission
Proceedings of 1994 IEEE International Conference on Microelectronic Test Structures, 2002An inverter matrix test circuit was designed for the Clementine space mission and is built into the RRELAX (Radiation and Reliability Assurance Experiment). The objective is to develop a circuit that will allow the evaluation of the CMOS FETs using a lean data set in the noisy spacecraft environment.

On Inverted Matrix Variate Gamma Distribution
Communications in Statistics - Theory and Methods, 2013In this article, we study several properties of the inverted matrix variate gamma distribution. Further, Bayes estimators using conjugate prior knowledge under square error loss function are also derived.

Inverting the Pascal Matrix Plus One
The American Mathematical Monthly, 2002Immediately we notice this is basically the same matrix, except with every other subdiagonal multiplied by a factor of negative one. Obviously this result generalizes to any size Pascal matrix, and there is something so beautiful and natural about this result that it hardly needs a proof (see Call and Velleman [2] for a particularly elegant ...

Study of Inverter System in MATRIX motor
2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020Recently, PMSM (Permanent Magnet Synchronous Motor) is widely used in terms of high efficiency and high torque density. In order to increase the penetration of PMSM, it is necessary to add further value like increasing torque, low noise and low vibration. In the previous research, A MATRIX motor has been proposed.
