This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...

This paper describes our proposed solution for the Yahoo! Learning to Rank challenge. The solution consists of an ensemble of three point-wise, two pair-wise and one list-wise approaches. In our experiments, the point-wise approaches are observed to outperform pairwise and list-wise ones in general, and the final ensemble is capable of further improving the performance over any single approach....

BACKGROUND The WISE (Whole System Informing Self-management Engagement) approach encompasses creating, finding, and implementing appropriate self-care support for people with long-term conditions. A training package for primary care to introduce the approach was developed and underwent formative evaluation. This entailed exploring the acceptability of the WISE approach and its effectiveness in ...

There are number of existing algorithms proposed that mines frequent patterns from certain or precise data. But know a day’s demand of uncertain data mining is increased. There are many situations in which data are uncertain. For frequent pattern mining from uncertain data mainly two approaches are proposed that are level-wise approach and pattern-growth approach. Level-wise approach use the ge...

The pair-wise comparison technique is a common approach for completing multi-attribute evaluations. However, this approach has limitations, especially for larger attribute sets, where the use of the technique is time-consuming because it requires a relatively large number of comparisons. The authors conducted an experiment to test the efficacy of three alternative approaches for eliciting prefe...

BACKGROUND AND PURPOSE Tract-based spatial statistics (TBSS) has been used to assess the integrity of the visual pathway in glaucoma patients. TBSS uses the subjects' FA data to create a mean FA skeleton of white matter tracts before running voxel-wise cross-subject statistics. We compared four different approaches of registration of FA maps to create the skeleton and evaluated alignment and su...

This paper reports results from social learning experiments where subjects choose between two options and each subject has a small chance of being perfectly informed about which option is correct. In treatment “sequence,” subjects observe the entire sequence of predecessors’ choices while in treatment “no-sequence” they only observe the number of times each option has been chosen. The theoretic...

Benjamini and Hochberg (1995) proposed the false discovery rate (FDR) as an alternative to the familywise error rate (FWER) in multiple testing problems. Since then, researchers have been increasingly interested in developing methodologies for controlling the FDR under different model assumptions. In a later paper, Benjamini and Yekutieli (2001) developed a conservative step-up procedure contro...
