Postdoc project description
================ 
The goal of the project is to demonstrate the possibility to detect and locate, in real-time, unusual or critical situations 
in urban areas (e.g., attacks, fires, sudden weather-related events, etc.), based on the analysis of mobile phone probe
network data. 
This detection will be complemented with information extracted from social networks (i.e., Twitter in the context of the 
project) and other sources of contextual data.

The Postdoc will have the unique opportunity to work on large-scale, already available mobile phone datasets, collected 
by the Orange French network provider, consisting in 2G, 3G and 4G network probe data, as well as more traditional 
Call Detail Records (CDR). 
Additionally, novel highly-detailed datasets on the usages of Internet mobile phone apps from mobile phone users will 
be specifically collected in the framework of the project, as well as detailed information on the nature, occurrence and 
location of possible incidents during the observed events. 

In a first phase, the activity of the postdoctoral candidate will consist in analyzing the collected data and extracting, 
via machine learning techniques and previous work from the team [2, 3].
In a second phase, the postdoctoral fellow is expected to explore and define efficient classification techniques [4, 5] 
for the inference of atypical situations (increase in the volume of the communication and consumption activity of certain
services, sudden growth of mobility-related events, change of signal shape, etc.).

From a methodological point of view, the main challenge is to develop a classification method that can work in real time. 
To achieve this goal, a method combining artificial intelligence (AI) and statistical learning will be designed and implemented 
(neural networks-based approaches, curve classification method, kernel method or generative method). 

As the volume of data to be analyzed is expected to be significant, the detection of anomalies and the periodic update
of local signatures will have to be carried out as close as possible to the source of the data flows so as to minimize network 
load and latency (Mobile Edge Computing).

From a technology perspective, the computational complexity of data mining requires the use of appropriate solutions 
for real-time and scalable implementation. 
As part of the project we will explore the use of Apache Kafka, TensorFlow and Apache Flink open source platforms 
to meet this criterion.

It is expected that the successful candidate will contribute to top-tier computer networks, self-adaptive distributed systems, 
big data and machine-learning conferences and journals (IEEE INFOCOM, IEEE ICDM, ACM SIGKDD, IEEE Big Data, 
IEEE Transactions on Autonomous and Adaptive Systems, IEEE Intelligent Transportation Systems, etc.).

Please do not hesitate to contact me [log in to unmask] or Pr. Nour-Eddin EL FAOUZI
[log in to unmask] and share CVs of any contact potentially interested to our proposal. 

We are ready to schedule a Skype interview to discuss more about the available position.
The postdoctoral position is expected to start in September/October 2020 at latest.
