This article studies the small weight codewords of the functional code CHerm(X), with X a non-singular Hermitian variety of PG(N, q2). The main result of this article is that the small weight codewords correspond to the intersections of X with the singular Hermitian varieties of PG(N, q2) consisting of q + 1 hyperplanes through a common (N −2)-dimensional space Π, forming a Baer subline in the ...

Supervised term weighting could improve the performance of text categorization. A way proven to be effective is to give more weight to terms with more imbalanced distributions across categories. This paper shows that supervised term weighting should not just assign large weights to imbalanced terms, but should also control the trade-off between over-weighting and under-weighting. Overweighting,...

The Thue–Morse (TM) sequence is defined via the binary substitution 1 7→ 11̄, 1̄ 7→ 1̄1; see [1, 4] and references therein for general background. The corresponding dynamical system is known to have mixed (pure point and singular continuous) spectrum [12, 15, 17], with a pure point part on the dyadic points and a singular continuous spectral measure in the form of a Riesz product. The latter coinc...

This paper describes a knowledge-poor anaphora resolution approach based on shallow meaning representation of sentences. Within our representation, we define a new local domain which provides a powerful cue for resolving pronominal anaphora. Other information used included syntactic information, syntactic parallelism and salience weights. We collected 111 singular 3 person pronouns from open do...

A new approach to robust performance problems is proposed in this paper. The approach involves the optimisation of so-called performance weights subject to a constraint, formulated in terms of the structured singular value, which ensures the existence of a stabilising feedback compensator that achieves robust performance with respect to the optimised performance weights and an uncertain plant s...
