Low Grade Matrices and Matrix Fraction Representations
The lgrade of a n × n matrix A is the largest rank of any subdiagonal block of a symmetric partition of A. A number of algebraic results on lgrade are given. When A has lgrade d, it can be be approximately decomposed as A = U + V , where U is an upper triangular matrix and V has rank d. If A satisfies GA = N with G and N have lower bandwidths dG and dN , then the decomposition is exact: A = U +...
متن کاملStrong convergence for variational inequalities and equilibrium problems and representations
We introduce an implicit method for nding a common element of the set of solutions of systems of equilibrium problems and the set of common xed points of a sequence of nonexpansive mappings and a representation of nonexpansive mappings. Then we prove the strong convergence of the proposed implicit schemes to the unique solution of a variational inequality, which is the optimality condition for ...
متن کاملExamining Pictorial Models and Virtual Manipulatives for Third-Grade Fraction Instruction
The purpose of this study was to examine pictorial representations, whether in static or dynamic modalities, and their impact on student learning in a classroom with low-achieving students. The investigation emerged from a classroom teacher’s action research project. During a three-week fraction unit, nineteen third-grade low-achieving students participated in two groups – a Dynamic Virtual Man...
متن کاملFrom Real World Problems to Domain Characterisations
Several problems associated with current approaches to knowledge acquisition have been identified by various workers. These include the lack of an explicit theoretical basis to many existing methodologies and the requirement to be able to integrate the analysis, elicitation and representation of knowledge into a coherent domain model. The purpose of this paper is to address some of these issues...
متن کاملApplying Supervised Learning to Real-World Problems
The last years have seen machine learning methods applied to an increasing variety of application problems such as: language, handwriting and speech processing , document classification, knowledge discovery in databases, industrial process control and diagnosis, fraud and intrusion detection, image analysis and many others. Our work starts from the realization that most of these problems requir...
