SHrimp: Descriptive Patterns in a Tree
نویسندگان
چکیده
The appliance of the minimum description length (MDL) principle to the field of theory mining enables a precise description of main characteristics of a dataset in comparison to the numerous and hardly understandable output of the popular frequent pattern mining algorithms. The loss function that determines the quality of a pattern selection with respect to the MDL principle is however difficult to analyze and the selection is computed heuristically for all known algorithms. With SHrimp, the attempt to create a data structure that reflects the influences of the pattern selection to the database and that enables a faster computation of the quality of the selection is initiated.

Four sampling sites were selected in different parts of the Anzali wetland watershed to predict the habitat preferences of the river prawn (Macrobrachium nipponens). A set of abiotic variables together with the abundance of the species were monthly measured at each sampling location during the 1- year study period (2017-2018). The results of Mann-Whitney test (given the non-normal data) showed ...

متن کاملPhylogenetic relationships of the commercial marine shrimp family Penaeidae from Persian Gulf
Phylogenetic relationships among all described species (total of 5 taxa) of the shrimp genus Penaeus, were examined with nucleotide sequence data from portions of mitochondrial gene and cytochrome oxidase subunit I (COI). There are twelve commercial shrimp in the Iranian coastal waters. The reconstruction of the evolution phylogeny of these species is crucial in revealing stock identity that ca...
