Grégoire Montavon received a Masters degree in Communication Systems from École Polytechnique Fédérale de Lausanne in 2009 and a Ph.D. degree in Machine Learning from the Technische Universität Berlin in 2013. He is currently a Research Associate in the Machine Learning Group at TU Berlin. His research interests are neural networks, machine learning and data analysis.

## Research

### 2015-2017: Explaining machine learning decisions

The goal of this project is to develop methods to explain the decisions (e.g. classifications) of machine learning models in terms of input variables (i.e. which input variables are relevant for the model's decision). Techniques that have been developed include the *deep Taylor decomposition*, that operates by performing a first-order Taylor expansion at each neuron of a deep network. These expansions are then recombined to produce a *relevance propagation algorithm*, where the model's decision is redistributed from layer to layer until the input is reached. www.heatmapping.org

### 2012-2013: Machine learning in the chemical compound space

The project consists of using machine learning to dramatically accelerate the calculation of molecular properties (e.g. atomization energy or polarizability) for large collections of molecules. These properties are usually obtained from complex physics simulations, that must be performed for each molecule individually. The machine learning speedup is mainly based on exploiting similarity between molecules, and on automatically extracting a more compact task representation. www.quantum-machine.org
