Fast anomaly detection in mobile phone data
Contract type : Fixed-term contract
Level of qualifications required : Graduate degree or equivalent
Fonction : Temporary scientific engineer
About the research centre or Inria department
The Inria research centre in Lyon is the 9th Inria research centre, formally created in January 2022. It brings together approximately 320 people in 19 research teams and research support services.
Its staff are distributed in Villeurbanne, Lyon Gerland, and Saint-Etienne.
The Lyon centre is active in the fields of software, distributed and high-performance computing, embedded systems, quantum computing and privacy in the digital world, but also in digital health and computational biology.
Context
This position integrates in the national PEPR Mobidec (https://pepr-mobidec.fr/) and more precisely in the Mob Sci-Dat Factory project (https://pepr-mobidec.fr/mob-sci-dat-factory-pc3). The selected researcher will join the Inria Agora team in the Inria Lyon center and will collaborate with other Inria teams and other institutes (IFPEN, IGN, CEREMA) in this framework.
Assignment
The person recruited will be in charge of studying unique mobile datasets shared as part of the project, in order to propose and evaluate algorithmic solutions for detecting, and even anticipating, anomalies in this type of data.
Main activities
The person recruited will bring significant contributions to the following points:
- Extraction of repetitive patterns from mobile telephony data collected by operators, in order to construct typical user and network behaviour. This behaviour will enable the automatic definition of anomalies, as situations that are sufficiently different from this typical profile.
- Implementation and evaluation of solutions for detecting the anomalies defined in the previous point. Compared with the state of the art, we will not be interested simply in metrics linked to the quality of detection, but also in the time taken to detect anomalies. The aim is to reduce this time as much as possible, and to detect anomalies at a very early stage. Modern artificial intelligence techniques, such as graph neural networks, will be studied.
Skills
Technical skills and level required : previous experience with large-scale mobile phone datasests.
