Example of explicit looping (1)

• Download

This workflow demonstrates how a nested workflow can be called an explicit number of times. Note that the loop iterator does not need to be used in the logic of the loop contents. It can be used as a sentinel (see the conditional workflow)

Calculation of distances, magnitutes and l... (4)

• Download

Calculation of distances, corrected apparent B magnitude mB-corr and luminosities with values gathered from the HyperLEDA database. This workflow receives a list of galaxy names (hyperLEDA names. ie: KIG0001) and a file with the morphological types of those galaxies Using the name of a galaxy, the workflow querys Hyperleda to extract some properties of this galaxy (J2000 Coordinates, velocity, galactic extinction,log of axis ratio, and the Total B-magnitude ). With this properties it calcula...

Sample IMPACT hackathon workflow (1)

• Download

Workflow that implements the Use Case for Group 2 at the IMPACT/Taverna hackathon. What it does is to take the URL of a TIFF image and compute the Levenshtein difference between the OCR output of the uncompressed version with various ones compressed at various bit rates.

Instance Selection and Prototype Based Rul... (2)

• Download

Example of Instance optimization using LVQ algorithm for training kNN classifier (Requires Instance Selection and Prototype Based Rules): Here we use FCM clustering to initialize LVQ network. The "Class assigner" is responsible for assigning class label for each cluster center, then obtained ExampleSet is used as codebooks initialization in the LVQ operator, which on the Prototype (Pro) output delivers the new optimized position of codebooks (prototypes) for training nearest n...
