Research Interests

My name is Mathieu Guillame-Bert, and I am working in Google Zurich. I did my Postdoctoral at CMU (Carnegie Mellon University) in the Auton-Lab (part of Robotic Institute) under the supervision of Artur Dubrawski. I defended my PhD in France in 2012 at the INRIA Research Lab in the PRIMA team under the supervision of James L. Crowley. I graduate from the Master of Advance Computing of the Imperial College of London, and from the "French Grande Ecole" ENSIMAG (Ecole Nationale Supérieure d'Informatique et de Mathématiques Appliquées) in 2009.

I am studying the automated extraction of patterns from large temporal datasets, as well as the use of those models for automated prediction, user interpretation and automated reasoning. Application domains I have worked on include Medical Diagnostics, Medical Forecastion, Human Activity Recognition and Forecasting, Banking Activity Patterns, Fault Detection and Prediction on complex systems, automatic Foreign exchange market trading, and a bit of Robotics.

Curriculum vitae

Softwares & Datasets

Click on this link bellow to see the softwares and the data-sets that I created or processed.

Softwares

• TITAR Learner
  TITAR (Temporal Interval Tree Association Rule Learner) is Temporal Data Mining algorithm able to extract temporal patterns from symbolic time series and time sequences. These patterns can then be used to user interpretation or for automatic forecasting.
• Event Viewer
  A powerful Time Sequences visualier. Event Viewer has been developed during the study of several real world problems. For that reason Event Viewer has a lot of unique features which allow a powerful understanding of data.
• Event Script
  Event script is a small but high level flow-oriented declarative programming language designed to facilitate the pre/post processing and the analysis of symbolic and numerical time series and sequences datasets.
• Machine Learning Lab.
  A small exploratory tool designed to test and experiment easily with several Machine Learning algorithms on several real work and sythetic datasets.

Public datasets

• The computer generated Database
  A syntetic data-set create to test symbolic time sequence data-mining algorithms.
• The Home Data Set
  The "Home activities dataset" of Tim van Kasteren et al. converted to be imported in TITARL and Event Viewer.
• Forex Dataset: Automated Trading Experiment
  A three years record of the USD/EUR Forrex market converted to be imported in TITARL and Event Viewer.

Personal area

I am a big fan of skiing and Salsa dancing.

The core of a robot made of legos
when I was a kid.

Apart from that, I enjoy DIY as well as making video games (which is kind of related). You can find some old video games and old DIY projects that I made when I was young on my old personal website at http://hokage.no.jutsu.free.fr/Achoum/.

In-game screen-shot of Build & Defend

Lately, I have created a game called Build & Defend. This is a multi-player survival cooperative game in a randomly generated and destructible world. This game is an experiment of some game-play concepts that I wanted to try for a long time. Also, I rely of lot on player feed backs as a direction to help developing the game. You can try this game at http://buildanddefend.com/. You can see the Indie DB web-page of this game at http://www.indiedb.com/games/build-defend. You can also follow me on twitter at @Achoum_GameDev.

I am also co-creator of the website http://nac-sitter.com/. Nac-sitter.com helps people to find somebody to keep their pets during holidays. This web-site focus mainly on NACs (Nouveau animaux de compagnie - "New pets" in english) such as rats, hamsters, rabbits, fishs, pogonas, etc.
