Most of the content of this post is platform-agnostic. Since in these days I’m using Azure Machine Learning, I take it as a starting point of my studies.
It’s quite simple for an Azure Machine Learning average user to create a regression experiment, make the data flow in it and get the predicted values. It’s also easy to have some metrics to evaluate the implemented model. Once you get them, the following questions arise:
- How can I interpret these numbers?
- Are these metrics enough to assess the goodness-of-fit of the model?
This post wants to provide you with the statistical foundation behind these metrics and with some additional tools that will help you to better understand how the model has fitted. These tools are implemented in a R script you can simply copy&paste into an Execute R Script module.

There is much focus from Microsoft on Azure right now, but Azure is reachable via Internet only. A typical company on the other hand, has all its resources on an internal LAN which is shielded from Internet for security reasons. So how can you connect the two and integrate Azure with your local network? (more…)
There have been a lot of changes in and around Microsoft in the past few months. Under the leadership of Satya Nadella, the push toward “cloud first” and “mobile first” services, things are stirred-up a bit right now. I have to admit that having worked with consulting clients who can’t, aren’t ready or just don’t want to move to the cloud; I’ve gotten a little caught up asking why it’s all necessary. The short answer is that cloud services are a reality. Just about everyone does business on the Internet in some way and, for technology product and service providers like Microsoft, it’s faster and more efficient to deliver to the cloud before shrink-wrapping boxes of software to be installed on traditional servers and desktop computers.

This week Microsoft announced the availability of Power BI Dashboards and the browser-based dashboard designer. What is it and why is it important? The most significant thing about it is that report and dashboard users do not need to have Excel 2013 ProPlus edition or an Office 365 subscription to use Power BI. This is very good news as it opens these amazing capabilities up to a much wider audience; those who work for companies that don’t have Office 2013 ProPlus or who are not using Office 365 ProPlus. Power BI updates and new features are being released at a very fast pace and there is much to consider. The definition of “Power BI” and Microsoft’s larger Business Intelligence and data analytics offering continues to evolve. First, exactly what’s new and recently available? (more…)
Great news yesterday and today the whole day after our Spanish SolidQ Summit 2012 in Madrid in Windows Azure with the new version of the Microsoft’s Cloud Platform full of new features and new names for the big amount of cloud services.
This article will review all Enterprise Search features, giving some examples. This will show all employees the value of using the Enterprise Search system in their organization. We will also explain each Search product individually, and cover each Enterprise Search feature. (more…)
It seems a recurrent topic this week in the SQL Azure forums, how do I remove an Azure Data Sync installation so I stop my syncing process and could delete all the Data Sync stuff (tables, stored procedures and so on) from my local databases?
Import and Export (CTP) is an interesting SQL Azure feature that allows us to Export a SQL Azure database in form of a bacpac to Azure storage. And think of bacpac as the “zipped” version of schema and data in your database. It also allows us to import the bacpac to a SQL Azure database. Also note that Import and Export CTP works also with on premise SQL server database and you can download the necessary bits and information here: http://sqldacexamples.codeplex.com/releases/view/72388
As I write this blog post, There are six location options while provisioning a SQL Azure server. And so while provisioning a SQL Azure server, who may have to decide the optimal location of the SQL Azure server based on the criteria that the latency between your application and the SQL Azure server is the minimum. And as you may know, we get better performance – if we are are able to minimize the latency between client and SQL Azure. So let’s get into action.
