Why is Matlab the best language for data mining? (cont’d)
In the previous post, I was arguing that Matlab is an excellent programming language (and environment) for data mining. However, as you know, no programming language is perfect. Matlab also has its drawbacks. Here are a few of them.First, Matlab is an interpreted language. Which means no compilation. The good thing is the on the fly programming-executing aspect. On the other side, there is no declaration or type

While starting a new project a few days ago, I had to answer the recurrent question: What language do I choose? In research, we have the opportunity of choosing any language, free or not. This is usually not the case in industry where the language can be fixed for many reasons (price, customer choice, boss choice, same as existing… Continue reading... | 3 CommentsStandardization vs. normalization

In the overall knowledge discovery process, before data mining itself, data preprocessing plays a crucial role. One of the first steps concerns the normalization of the data. This step is very important when dealing with parameters of different units and scales. For example, some data mining techniques use the Euclidean distance. Therefore, all parameters should have the same scale for a fair comparison between them.Two methods are usually well Filed under: data preprocessing, normalization, scaling, standardization
How to explain data mining to your mother
Like many subjects related to computer science, data mining is a complex area. More than that, it is interdisciplinary and applicable in many domains. Working in data mining (whether you come from computer science or not is of no importance) is one of these job that is difficult to explain to your friends and family. Perhaps your friends work with technology or at least they now it, but what about… Continue reading... | 1 CommentMore data mining blogs
Welcome back to Data Mining Research (DMR) for those who read regularly. If you're new to DMR, I hope you'll find some useful posts. In addition, feel free to participate by commenting posts.After I publish a list of data mining blogs, some people commented on their own blog (and that was the aim of the original post). Here, I want to mention two blogs related to data mining and which… Continue reading...Data Mining Research
