I am teaching the course “Big data and network science” as part of the Digital Masters if the CRI, along with Liubov Tupikina, Loic Saint Roch, Anirudh Krishnakumar, and Felix Schoeller. The course will take place on Wednesdays 9am-12pm beginning 16 October 2019 to 22 January 2020
This course will provide an introduction to the field of big data, with a focus on network data and data for mental health. Topics will cover data project management, infrastructure of big data, data analysis and visualisation, and mental health data. The course will be divided into a big data and a network data parts.
Why focus on network data? Over the past century, network studies have had significant impact in disciplines as varied as mathematics, sociology, physics, biology, computer science or quantitative geography, giving birth to Network Science as a field of itself. With the recent rise of social networks in the last decade, their use has now become widespread in the digital world. Here we will provide an introduction to the field of Network Science, from the theoretical foundations (generating, analysing, perturbing networks) to the practical hands-on part (analysis and visualisation of a real-world networks).
Network topics will cover:
a. How to construct networks from real data?
b. How to analyze networks? (centrality measures, community detection, statistical analyses etc.)
c. How to visualise networks?
d. Dynamics and spreading phenomena on networks (epidemics / information spreading, diffusion)
e. How do networks wirings change in time? (network robustness, temporal networks)
f. How to represent more complex network data? Multilayer, multiplex networks.
Students will select, analyse and present a network of their choice as part of a personal project for the course. They will also choose an advanced topic in network science & big data for which they will make a presentation in a reverse classroom setting. They will in particular contribute to a wikipedia page about that topic.
Data Efforts in Big Data for Mental Health part:
In this part, students will be presented with topics related to the infrastructure of ‘big data’. They will be introduced to barriers, current trends, types, protocols and importance of ‘big data’ collection in the sphere of mental health, specifically through the
(i) Healthy Brain Network project for 10000 children collecting and sharing neuroimaging & phenotypic data.
Students will also contribute to the development of :
(ii) A Linked Semantic Mental Health Database and scientific framework mapping signs, symptoms and behaviors to subjective and objective measures, projects and technologies (https://github.com/ChildMindInstitute/mhdb/wiki)
(iii) MindLogger Data Collection Platform & App to dramatically improve the convenience, consistency, efficiency, accuracy & analysis of widely distributed data efforts (https://mindlogger.org/)
Students will then spend the last part of the course working on a research project developing and applying digital tools related to ‘big data’ and mental health, using the skills obtained from the first part of the course.
