Personal Profile

My name is Tiago Pereira and I'm from Gondomar.

I used to practice a lot of sport but then I took an arrow to the knee. I still try to play whenever I get the chance to go with some friends. I enjoy play video games, although not being very good at it, but they are a way to relax and unwind after a week of work (when I have time that is).

I like to go out at night to a quiet bar or have dinner with friends. I have very different tastes in music and I also love to travel, the world has more to offer than just programming.

I consider myself a well presented, dynamic, motivated, highly committed, responsible and organized person, with entrepreneurial and communication skills able to establish good interpersonal relationships.

Thesis

DataMining4Dummies

A web application for the automatic selection of data mining algorithms for new problems

Advisor: Carlos Manuel Milheiro de Oliveira Pinto Soares [web]

Co-Advisor: Pavel Bernard Brazdil [web]


The interest in the area of classification and prediction is growing rapidly in industry and commerce. A large number of data mining tools are already available. However, such tools are still of limited use to end-users who are not experts. This is due to the fact that machine learning algorithms are non-trivial. As a result, users of machine learning/data mining systems are faced with two major problems: selecting the most suitable algorithm to use on a given dataset, and combining this algorithm with useful and effective transformations of the data. Traditionally, these problems are solved by trial-and-error or consulting experts. The first solution is time consuming and unreliable, while the second is expensive and based on preferences of the experts. Clearly, neither solution is completely satisfactory for the non-expert end-users. Therefore automatic and systematic guidance is required.

By analysing the state of the art we can see how different attempts have been made to address this problem. Some examples are StatLog, ML Toolbox, METAL and DM Advisor, to name a few. Although some of them have shown very interesting results, they are still tool restricted and present a lack of satisfactory user guidance, simplicity and process transparency. In DM Advisor, two of the main shortcomings are the systems scalability and the project did not took full advantage of its distributed approach.

The focus of this dissertation is to improve support to machine learning/data mining end-users, by creating a new system that will allow the recommendation and use of the most promising algorithms in a distributed and collaborative way. This thesis will integrate DM Advisor with OpenML, by collecting its most significant meta-features and applying a meta-learning technique to learn from the collected experiments. The distributed concept introduced by DM Advisor will also be rebuild to take fully advantage of the distributed execution strategy. Finally, the developed system will also have the ability of sharing data with others through OpenML.
