In this paper, the authors present two such degrees of similarity measures for multiple valued data types and deal with the clustering of such multiple valued data considering real life examples. The dataset considered is of 50 individuals and their areas of study and the areas of expertise in ...

Firstly, the definitions of three categories of temporal data, time series, event sequence, and transaction sequence are presented, and then the current techniques and methods related to various sequences with similarity measures, representations, searching, and various mining tasks getting involved are...
Similarity measures provide the framework on which many data mining decisions are based. Tasks such as classification and clustering usually assume the existence of some similarity measure, while fields with poor methods to compute similarity often find that searching data is a cumbersome task. Several...
Five most popular similarity measures implementation in pythonThe buzz term similarity distance measures has got wide variety of definitions among the math and data mining practitioners. As a result those terms, concepts and their usage went way beyond the head for beginner , who started to ...
which can hold most information of the original time seiries and reduce the calculating complexity.Experimentally compares the four similarity measures on three database under group-ward hierarchical clustering,evaluates the results objectively and subjecttively respectively,and is shown to yield useful ...
Traditional approaches for defining similarity between two attributes typically consider only the values of those two attributes, not the values of any other attributes in the relation. Such similarity measures are often useful, but unfortunately, they cannot reflect certain kinds of similarity. ...
Similarity measures utilized in IR systems can distort one’s perception of the whole data set. For example, if a user types a query into a search engine and does not find a satisfactory answer in the top ten returned web pages, then it will usually try to reformulate this query once or...
Text similarities play a big role in data mining. A lot of similarity measures have been used in different domains. Most of the measures are corpus dependent or language dependent. When some measures are good to compute word-to-document matching, they are unable to compute document-to-document...
A new similarity measure for gene expression data, CorHsim, is proposed. It is compared with the other two commonly used measures over some very simple examples. Together with the other two measures, it is impleme...
