متن کاملConcentration of Multivariate Statistical Tables
In this paper we lay the foundation of the concentration measurement for statistical tables with more than two columns. A concentration function and a coefficient of concentration are defined which can be used in a similar way as the Lorenz diagram and the Gini coefficient in case of tables with two columns. For computational purposes we derive an explicit formula and give an algorithm. The mat...
متن کاملThe Complexity of Three-Way Statistical Tables
Multiway tables with specified marginals arise in a variety of applications in statistics and operations research. We provide a comprehensive complexity classification of three fundamental computational problems on tables: existence, counting, and entry-security. One outcome of our work is that each of the following problems is intractable already for “slim” 3tables, with constant number 3 of r...
متن کاملSampling Phrase Tables for the Moses Statistical Machine Translation System
The idea of virtual phrase tables for statistical machine translation (SMT) that construct phrase table entries on demand by sampling a fully indexed bitext was first proposed ten years ago by Callison-Burch et al. (2005). However, until recently (Germann, 2014) no working and practical implementation of this approach was available in the Moses SMT system. We describe and evaluate this implemen...
