An Online Repository of Mathematical Samples

Baker, Josef B., Sexton, Alan P., Sorge, Volker

Similarity:

With a growing community of researchers working on the recognition, parsing and digital exploitation of mathematical formulae, a need has arisen for a set of samples or benchmarks which can be used to compare, evaluate and help to develop different implementations and algorithms. The benchmark set would have to cover a wide range of mathematics, contain enough information to be able to search for specific samples and be accessible to the whole community. In this paper, we propose an...

Article Disassembly - New Ways to Handle Information in Publications

Holl, András (2012)

Serdica Journal of Computing

Similarity:

ACM Computing Classification System (1998): I.7.4. Articles and books – the basic publication units – could be disassembled to semantic building blocks. For scientific journal articles, such blocks include figures and tables, among others. Providing meta-data for figures and tables, and making them accessible per se, opens up new ways of presenting and using scientific information—like producing an image database on certain subjects, based on figures published in different...

Experiments with two Approaches for Tracking Drifting Concepts

Koychev, Ivan (2007)

Serdica Journal of Computing

Similarity:

This paper addresses the task of learning classifiers from streams of labelled data. In this case we can face the problem that the underlying concepts can change over time. The paper studies two mechanisms developed for dealing with changing concepts. Both are based on the time window idea. The first one forgets gradually, by assigning to the examples weight that gradually decreases over time. The second one uses a statistical test to detect changes in concept and then optimizes the...
