Graph Format Conversion is used to convert data files in specific graph formats to a list of edges represented as a Dataset in Azure ML.
This is a part of a series of custom modules based on the CRAN igraph package. Graph Format Conversion is used to convert data files in specific graph formats to a list of edges represented as a Dataset in Azure ML. Here is an example showing how to convert a graph dataset in Pajek NET format. The dataset first needs to be packaged in a zip file and uploaded to Azure ML as such. ![enter image description here][1] In this example, power_grid.paj represents an undirected, unweighted network representing the topology of the Western States Power Grid of the United States. It can be downloaded from the [UCI Network Data Repository][2]. Please note that the source file inside the ZIP file does not need to have an extension, but its file name must match the parameter Input File Name as shown here. This is what the output looks like. The output dataset is represented in two columns as a list of edges where each value in each column represents a Node Id and each row represents an edge, as shown here. ![enter image description here][3] [1]: https://alvilcek.blob.core.windows.net/azuremlcustommodules/Azure%20ML%20Custom%20Modules/documentation/Graph_Format_Conversion_1.PNG [2]: https://networkdata.ics.uci.edu/data.php?id=107 [3]: https://alvilcek.blob.core.windows.net/azuremlcustommodules/Azure%20ML%20Custom%20Modules/documentation/Graph_Format_Conversion_2.PNG
