Context of the Challenges:

The impact of environmental factors, including pollution and socio-economic development, on the incidence of cancer remains unknown. Countries that have adopted similar socio-economic development models and exposed to comparable environmental situations have different cancer incidences. This underlines the need to refine our models of understanding of the epidemiology of cancers. The consequences of a better understanding of the the evolution of cancers and their causal factors are important both from a medical and a public health point of view, as a result of prioritizing the public health actions that would be deduced therefrom, and Better targeting of possible prevention campaigns.

The public recent and massive availability of socio-economic data (economic development, mass consumption), demographic and environmental factors (pollution, exposure to carcinogens, urban planning data) and the development of new approaches to Statistics (machine learning) makes it possible to envisage better predictions of the incidence of the cancers.

By making large data sets widely available and covering the usual epidemiological themes, Epidemium calls on collective intelligence to build models for visualizing and anticipating the spatio-temporal evolution of cancers and thus opens the possibility for all to contribute to the knowledge of the dynamics of cancers and their determinants.

The Challenges:

Challenge 1: See cancers
Visualization challenge
Challenge 2: Foresee cancers
Prediction challenge (the incidence of cancers)
Challenge 1 See cancers.png Challenge 2 Foresee cancers.png
Constructing a Data-Visualization of the incidence of cancers by exposing the epidemiological factors associated with their dynamics.

The challenge consists in developing data visualization tools aimed at the general public and the medico-scientific community at large. Particular attention should be given to design with regard to user experience. These tools will have to integrate the variables and results of the prediction challenge, highlighting the dynamic changes in time and space of potential risk factors.

Developing a predictive tool for the progression of cancer in time and space,depending on the known or supposed factors that determine its evolution.

The challenge consists in developing of a predictive tool for the incidence of cancers.The data used to learn the models are detailed below.

The Training set will be composed of the data covering the period from 1950 to 2003.The validation set will be composed of the data covering the period from 2003 to 2007.Note that the data from 2007 to 2012 in the process of being obtained and will be Integrated into the validation set.

This challenge is divided into two distinct parts: 1/ prediction in the world, 2/ prediction by country.

The winning team will be the one whose prediction will be the most efficient on the validation set. A leaderboard will be set up with real-time updating.
