Research Interests

My name is Mathieu Guillame-Bert, and I am working in Google Zurich, Switzerland.

I did my Postdoctoral at CMU (Carnegie Mellon University) in the Auton-Lab (part of Robotic Institute) under the supervision of Artur Dubrawski. I studied the use of rule extraction and decision forest-like techniques for symbolic and numerical time series. Typical applications include Automated and/or assisted Medical Diagnostics, Medical Forecasting, 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.

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 studied 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.

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.

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.
