Ekrem Kocaguneli: How big is your data?
http://www.kocaguneli.com/2013/01/how-big-is-your-data.html
Ekrem Kocaguneli: Software Development Engineer II at Microsoft. Thursday, January 24, 2013. How big is your data? I think one of the best ways to describe the popularity concept is to start with a toy example. Assume that we have a data set of N instances (rows) and D features (columns). Let's say that we found out the k-. Many nearest neighbors of every instance. For the sake of this example let's fix k=1,. How to of QUICK. To begin with, the concept of popularity and the QUICK algorithm (developed on ...

Ekrem Kocaguneli: Software Development Engineer II at Microsoft. Monday, July 15, 2013. Distributed Development Considered Harmful? Distributed development is a good use of contemporary collaboration technology and the universal talent pool of software engineers. However, it also comes with various possible challenges. Our third rule is to “reflect” on results to avoid confusing practitioners with an arcane mathematical analysis. For example, on reflection, we found that the effect size o...Our conclusio...

Ekrem Kocaguneli: Software Development Engineer II at Microsoft. Wednesday, June 10, 2015. It has been some time. Or what I have been up to. Outside of work, most of my time was dedicated to book projects that I was lucky enough to be involved in. The first book that I had the chance to co-author, with amazing collaborators Tim Menzies. Fayola Peters and Burak Turhan. Is called "Sharing Data and Models in Software Engineering" (here is the Amazon link: http:/ bit.ly/shrngDtMdls. That led to our chapter in.

Ekrem Kocaguneli: About PhD Defense
http://www.kocaguneli.com/2012/11/about-phd-defense.html
Ekrem Kocaguneli: Software Development Engineer II at Microsoft. Tuesday, November 20, 2012. Two weeks ago, I successfully defended my PhD thesis: "A Principled Methodology: A Dozen Principles of Software Effort Estimation." I have been willing to write this post right after my PhD defense, but maybe it is better that some time has passed and I had more time to think about it. I will not necessarily write about the details of my PhD thesis in this post (but in case you want to read the details, here.

Ekrem Kocaguneli: Software Development Engineer II at Microsoft. Monday, October 1, 2012. Ground Zero: When do I have perfect data? Probably anyone who has dealt with real-world data has a grin on his face after reading this title. Most likely, because of the fact that they know the answer is. well, never. Unfortunately there is no formula or silver-bullet answer to perfect data. This is mainly due to the fact that reaching the right data is an interplay of various different factors such as:.

Ekrem Kocaguneli: Looking for something on transfer learning (a.k.a. cross-company learning) ?
http://www.kocaguneli.com/2013/07/looking-for-something-on-transfer.html
Ekrem Kocaguneli: Software Development Engineer II at Microsoft. Thursday, July 18, 2013. Looking for something on transfer learning (a.k.a. cross-company learning)? In the machine learning community. The basic idea of transfer learning is being able to learn when the source and the target domains are different or when the source and the target tasks are different. How to handle insufficient number of labeled instances? In this position paper, we investigate synergies between different learning methods (...
