Differential Privacy: a new notion of the privacy for a new paradigm of data?

The recent advances of technology, that make the storage and processing of large amount of data affordable, have led to increasing collect of sensitive data. A consequence of the Big Data phenomenon is that the traditional definition of what is a personal information, used to define boundary of privacy, seems inaccurate. Indeed, "anonymized" dataset can be massively reidentificate, and increases further desanonymization in a vicious circle. Differential Privacy has been proposed as a more relevant way ta measure to what extend a contribution to a database threatens the individual, and it has become the gold standard in Machine Learning research. I will briefly present the key points of the definition, highlight its strengths and the issues that are imposed by this framework.

Philosophical work on COMPAS

What place for a software that predicts recidivism in the US justice ?

Compas is a popular risk assessment tool used by several states in the United States of America as a piece of information for criminal sentencing. We discuss its legitimacy in the judicial framework. As it relies on machine learning, which use big data to optimize a predictive model, specific questions of fairness arise. It has a cost in terms of transparency and bias might come from the racial bias of the past and current society that generates the training data. We study these questions and show that awareness is welcome to avoid the amplification of norms based on statistics, as it might not be compatible with human notion of justice.

Time predictions for fire brigade

Course project with real impacts ?

We worked on the prediction of the response time of fire brigades in Paris. It is one of the most important factors for emergency services because their ability to save lives and rescue people depends on it.

We shared our code with the organizers that work on a mixed solution of several participants.

Ramsey Theory

Work for ENS entrance

As an introduction to research, I did a bibliography work with a toy implementation on Ramsey theory. I first report is here. A second one is focused on van der Waerden's theorem.

You can also look at this slides slides for a small introduction.
