Workflows

Gaussian Blur (1)

• Download

Convolves the image with a Gaussian kernel wherein the Gaussian has a standard deviation specified by the user ("sigma") and the kernel width in each dimension is 6 times the standard deviation of the Gaussian. You can find more details here

galaxy_101 (2)

• Download

  This is a Galaxy pipeline written using the Galaxy 101 tutorial (https://main.g2.bx.psu.edu/galaxy101). The pipeline involves retrieving genome and SNP data from UCSC for a particular chromosome. These data are integrated in order to find exons with the highest number of SNPs.

TextualAttributeExtraction for Recommender... (1)

• Download

This workflow takes conent data from VideoLectures.Net Recommender System Challenge and extractes word-vectors for each lecture. Latent semantic analysis with Singular Value Decomposition is done on item-word binary matrix. The last step is the binomializaiton of dataset.

Evaluating semantic kernel with k-NN class... (1)

• Download

This workflow uses k-NN classifier to evaluate quality of EL++ Convolution Kernel [1]. As a dataset one of the examples from DL-Learner project [2] is used. After preparing knowledge base with "Build Knowledge Base", the item to item distance matrix is computed with "Calculate Gram/Distance Matrix". Such a matrix is then used as an input to 10-fold cross-validation with k-NN as an classifier and average result is delivered. [1] L. Józefowski, A. Lawrynowicz, J...

Semantic clustering with k-Medoids and ALC... (1)

• Download

 This workflow loads data from a configuration file for DL-Learner (http://dl-learner.org) and uses ALCN Semantic Kernel [1] to cluster those data with k-Medoids algorithm. [1] N. Fanizzi, C. d’Amato, F. Esposito. Learning with Kernels in Description Logics. ILP 2008

Clustering data from DBpedia using AHC (1)

• Download

 This workflow uses Aglomerative Hierarchical Clustering algorithm to build hierarchy of clusters on data downloaded from DBpedia, the semantic version of Wikipedia. RDF data are downloaded from SPARQL endpoint and merged with DBpedia ontology by "Build Knowledge Base". Set of items to cluster is selected with "SPARQL Selector" and later they are clustered by "Agglomerative Hierarchical Clustering" with distance measure induced by the Bloehdorn Kernel [1]. ...

Anatomical Atlas Generation (1)

• Download

Computes an anatomical atlas based on a set of patient images using registration methods. This workflow is automatic and does not require user interaction. The anatomical atlas is composed of a mean image and the set of transformations for each patient's between the mean image and the patient image. The atlas can be used to segment the mean image once and propagate the segmentation results to each patient image automatically. This workflow has been tested using GIMIAS-1.5 (open source) with ...

Convert table to CDS format (1)

• Download

It converts a csv file (comma separated values) to the CDS format. It also provides relevant information to create the ReadMe file. The first row in the input file must be the column names. If you want to run this workflow, you have to install astrotaverna plugin. You can easyly cusomize the workflow to provide a votable or fits table as input.
