Extended Sign Test by Ranks for Ordered Repeated Measure

Minimum ranks of sign patterns via sign vectors and duality

A sign pattern matrix is a matrix whose entries are from the set {+,−, 0}. The minimum rank of a sign pattern matrix A is the minimum of the ranks of the real matrices whose entries have signs equal to the corresponding entries of A. It is shown in this paper that for any m×n sign pattern A with minimum rank n− 2, rational realization of the minimum rank is possible. This is done using a new ap...

A Measure for Data Set Editing by Ordered Projections

In this paper we study a measure, named weakness of an example, which allows us to establish the importance of an example to find representative patterns for the data set editing problem. Our approach consists in reducing the database size without losing information, using algorithm patterns by ordered projections. The idea is to relax the reduction factor with a new parameter, λ, removing all ...

Width Hierarchies for Quantum and Classical Ordered Binary Decision Diagrams with Repeated Test

We consider quantum, nondterministic and probabilistic versions of known computational model Ordered Read-k-times Branching Programs or Ordered Binary Decision Diagrams with repeated test (kQOBDD, k-NOBDD and k-POBDD). We show width hierarchy for complexity classes of Boolean function computed by these models and discuss relation between different variants of k-OBDD.

Modelling of repeated ordered measurements by isotonic sequential regression

Do repeated references result in sign reduction?

Previous research has shown that repeated references are often reduced compared to initial references. The present study looks at the production of repeated references by signers of Sign Language of the Netherlands (NGT). Participants had to describe figures to an addressee, who had to pick the correct figure from a large group of figures. Several figures had to be described several times. The ...
