Algorytm DBScan (1)

Download

Przeplyw ilustruje sposob wykorzystania algorytmu DBScan do znalezienia modelu skupien. Algorytm DBScan jest przykladem algorytmu bazujacego na gestosci, parametr epsilon wskazuje na promien sasiedztwa, a parametr min points wskazuje na minimalna liczbe punktow, jakie musza sie znalezc w sasiedztwie punktu aby kontynuowac rozrastanie sie skupienia.

Wybor parametru k dla algorytmu k-Means (1)

Download

Proces pokazuje, w jaki sposob mozna eksperymentalnie dobrac wlasciwe wartosci parametru k (liczba poszukiwanych skupien) dla algorytmow k-Means i k-Medoids. Jako miary oceny podzialu wykorzystano srednia odleglosc od centroidu oraz indeks Daviesa-Bouldina

miRNA GFF to entrez gene (1)

Download

This workflow reads a GFF file of miRNA cooridinates and uses BioMart to search human ensemble genes for the gene that codes for the miRNA. The workflow returns a list of miRNAid, chromosome, start, stop, strand, entrez gene id, gene name, gene strand. Example input file here: ftp://mirbase.org/pub/mirbase/CURRENT/genomes/hsa.gff

Using Remember / Recall for "tunneling" re... (1)

Download

This process shows how Remeber and Recall operators can be used for passing results from one position to another position in the process, when it's impossible to make a direct connection. This process introduces another advanced RapidMiner technique: The macro handling. We have used the predefined macro a, accessed by %{a}, that gives the apply count of the operator. So we are remembering each application of the models that are generated in the learning subprocess of the Split validation. Af...

Warning: The files are hardcoded in to the beanshell of this workflow. Given an orthlog file for an organism from http://www.ebi.ac.uk/integr8/FtpSearch.do? orgProteomeId=22602, find proteins that are orthologous to proteins in another oragnsims, e.g., B.subtils. Outputs percent.
