This article tackles the Authorship Attribution task according to the language independence issue. We propose an alternative of variable length character n-grams features in supervised methods: maximal repeats in strings. When character ngrams are by essence redundant, maximal repeats are a condensed way to represent any substring of a corpus. Our experiments show that the redundant aspect of n...

Phospho3D is a database of three-dimensional (3D) structures of phosphorylation sites (P-sites) derived from the Phospho.ELM database, which also collects information on the residues surrounding the P-site in space (3D zones). The database also provides the results of a large-scale structural comparison of the 3D zones versus a representative dataset of structures, thus associating to each P-si...

ADGO 2.0 is a web-based tool that provides composite interpretations for microarray data comparing two sample groups as well as lists of genes from diverse sources of biological information. Some other tools also incorporate composite annotations solely for interpreting lists of genes but usually provide highly redundant information. This new version has the following additional features: first...

We have built a protein subcellular localization annotation database, the DBSubLoc database, which is available at http://www.bioinfo.tsinghua. edu.cn/dbsubloc.html. Annotations were taken from primary protein databases, model organism genome projects and literature texts, and then were analyzed to dig out the subcellular localization features of the proteins. The proteins are also classified i...

This paper describes a framework for improving recognition performance and user experience in large scale alphanumeric listings commonly used in conversational speech applications for enterprise. The performance of these speech recognition grammars is severely impacted due to the poor recognition of alphabets. We propose a new approach based on augmenting performance through redundant semantic ...

In this paper, an algorithm for identifying five different varieties of rice, using the morphological features is presented. The proposed algorithm consists of several steps: image acquisition, segmentation, feature extraction, feature selection, and classification. Eighteen morphological features were extracted from rice kernels. The Set of features contained redundant, noisy or even irrelevan...

When rules of transfer-based machine translation (MT) are automatically acquired from bilingual corpora, incorrect/redundant rules are generated due to acquisition errors or translation variety in the corpora. As a new countermeasure to this problem, we propose a feedback cleaning method using automatic evaluation of MT quality, which removes incorrect/redundant rules as a way to increase the e...

In this paper, an image-adaptive watermarking technique based upon a redundant wavelet transform is proposed. The redundant transform provides an overcomplete representation of the image which facilitates the identification of significant image features via a simple correlation operation across scales. Although the watermarking algorithm is image adaptive, it is not necessary for the original i...

Non-redundant protein datasets are of utmost importance in bioinformatics. Constructing such datasets means removing protein sequences that overreach certain similarity thresholds. Several programs such as 'Decrease redundancy', 'cd-hit', 'Pisces', 'BlastClust' and 'SkipRedundant' are available. The issue that we focus on here is to what extent the non-redundant datasets produced by different p...

The problem of feature selection has long been an active research topic within statistics and pattern recognition. So far, most methods of feature selection focus on supervised data where class information is available. For unsupervised data, the related methods of feature selection are few. The presented article demonstrates a way of unsupervised feature selection, which is a two-level filter ...
