Œis paper presents a new algorithm for calculating hash signatures of sets which can be directly used for Jaccard similarity estimation. Œe new approach is an improvement over the MinHash algorithm, because it has a beŠer runtime behavior and the resulting signatures allow a more precise estimation of the Jaccard index.

Magnetic resonance imaging (MRI) is an effective imaging modality for identifying and localizing breast lesions in women. Accurate and precise lesion segmentation using a computer-aided-diagnosis (CAD) system, is a crucial step in evaluating tumor volume and in the quantification of tumor characteristics. However, this is a challenging task, since breast lesions have sophisticated shape, topolo...

Statistical association measures have been widely applied in information retrieval research, usually employing a clustering of documents or terms on the basis of their relationships. Applications of the association measures for term clustering include automatic thesaurus construction and query expansion. This research evaluates the similarity of six association measures by comparing the relatio...

Rice as one of the most important agricultural crops has a putative potential for ensuring food security and addressing poverty in the world. In the present study, in order to provide basic information to improve rice through breeding programs, Inter Simple Sequence Repeat marker (ISSR) was used For DNA fingerprinting and finding genetic relationships among 32 different cultivars. In this study...

The Jaccard index is a standard statistics for comparing the pairwise similarity between data samples. This paper investigates the problem of estimating a Jaccard index matrix when there are missing observations in data samples. Starting from a Jaccard index matrix approximated from the incomplete data, our method calibrates the matrix to meet the requirement of positive semi-definiteness and o...

Management of legacy software and its code, generally written in procedural languages, is often costly and time-consuming. To help this management, a migration from procedural to object oriented paradigm could be a cost effective option. One approach for such migration can be based on the underlying dependency structure of the procedural source code. In this work, we propose a new heuristic alg...

As traditional topic detection under the online social network is lack of mining the topic semantic features and dynamic evolution characteristics, this paper studies the semantic features and dynamic evolution trend based on topic temporal chain under the online social network. According to the temporal relations, text flows are divided into the text set in continuous time slice, then combinat...

We used the RAPD-PCR method for distinguishing the main Old World Leishmania parasites Leishmania tropica, L. major, and L. infantum and applied it to Sauroleishmania species from Iran. Twelve out of 21 tested primers were suitable for identification of these parasites. The Jaccard similarity index was 0.30 for L. tropica and L. infantum as well as for L. major and L. infantum. The similarity c...

In today’s digital society, electronic information is increasingly shared among different entities, and decisions are made based on common attributes. To address associated privacy concerns, the research community has begun to develop cryptographic techniques for controlled (privacy-preserving) information sharing. One interesting open problem involves two mutually distrustful parties that need...
