Error while creating a web service for a predictive experiment in Azure Machine Learning Studio (AzureML)

For a project for the detection of the content emails, I’ve created anAzureML experiment. But it was not possible to create a web service from the predictive experiment. After several minutes, Machine Learning Studio reported the following error:

Service call failed due to a network error.
Error when requesting https://europewest.studioapi.azureml.net/api/workspaces/017690d3ae8c44829bbxxxxxxxxxxxxxxxxxx/webservicegroups/xxxxxxxxxxxxxxxxxxxxxxxxx/modelpackages/

It took me days to find out why. In my case, it’s because that the function „Feature Hashing“

How to generate a SAS-Token to access Microsoft Azure Event Hub (PowerShell, AzureEventHub, Azure)

For an upcoming project I will send short data telegrams to an Event Hub on Microsoft Azure. I have some experience with calling different services on Azure via API (e.g. Azure Machine Learning). But the authorization to an Azure ML Web Service and to an Event Hub is very different. Azure ML only requires an Authorization BEARER. Event Hub needs a SAS-Token. It took some time to find out how to generate a correct authorization string.

Fun with Microsoft Azure Machine Learning #AzureML – Szenario: Roulette Permanenzen

Im Dezember habe ich auf dem sepagoForum in Köln einen eher unterhaltsamen Vortrag zu Azure Machine Learning gehalten: „Fun with Azure Machine Learning“. Neben einer kurzen Einführung in neuronale Netze und AzureML habe ich verschiedene Szenarien vorgestellt. In den Szenarien habe ich gezeigt, ob neuronale Netze bestimmte Aufgaben lösen können oder eben nicht. Eines dieser Szenarien stelle ich hier vor.

Szenario: Roulette Permanenzen

Wer schon mal in einem Casino war, hat es bereits gesehen: Es gibt Menschen,

Fun with Microsoft Azure Machine Learning #AzureML – Scenario: Roulette Permanencies

In December, I gave an entertaining lecture on Azure Machine Learning during our sepagoForum event in Cologne, titled „Fun with Azure Machine Learning“. In addition to a brief introduction to neural networks and AzureML, I presented a few different scenarios, in which I tried to figure out which neural networks may or may not solve specific tasks. One of these scenarios is presented here.

Scenario: Roulette permanencies

If you have ever have been to a casino you have probably seen this: There are people who note where the ball landed last,

Updated: Use PowerShell Module OneDrive from PowerShellGallery to work with OneDrive via command line

21wrote a PowerShell module to work with OneDrive via command line. The module use the documented OneDrive web API from Microsoft (https://dev.onedrive.com/README.htm). If you already have the module PowerShellGet to access PowerShellGallery installed, you can easily download this module with a single command:

Install-Module -Name OneDrive -Scope CurrentUser

You can update the module to a newer version with the same command (add -force). If you don‘t use PowerShellGet currently,

Improved Datamining using Azure Machine Learning #AzureML – Part 2 – Technical Details

Techincal Details

The analysis of new tweets based on “learning” is built using a 4-tier application in Microsoft Azure:

Azure machine learning API:

AzureML provides the prediction model and can be accessed through the web job using the API.

Web job in Azure:

The job (c#) reads new tweets once an hour and passes them to AzureML for classification. The prediction of each tweet is stored in the Azure SQL database.
