Apply to the BigSkyEarth Training School: Big Data in Simulations and Observations

BigSkyEarth is organizing its final Training School, focused on Big Data in simulations and observations. It will take place at the Tuorla observatory, the University of Turku, on Nov. 26 – Dec.1, 2018. Key practitioners from the astronomy, the Earth observation and the computer science domains will be participating in the School contributing the perspectives of both the academic and the industrial sector. Grants will be made available by the Action for a number of participants. The procedure for applying and for the selection of participants is described below.

Past editions of the Training School

The 1st edition of the BigSkyEarth Training School took place at the German Aerospace Center facilities in Oberpfaffenhofen, Germany, 4-9 April, 2016. It gathered around 30 researchers for hands-on training on Big Data analytics in astronomy and Earth observation with six expert instructors from the EU and the USA. The second edition took place in Preston at the University of Central Lancanshire, UK, on April 3-8 2017 and focused on the creation of effective visualisations of big data bases. The third edition was held at the Vicomtech Research Center, Spain, in April 3-9, 2018.

Eligibility Rules

Applicants can be PhD students or PhD holders from any country. However, only applicants from BigSkyEarth COST countries and institutions are eligible for the financial support provided by BigSkyEarth (see the list of countries and institutions below). There will be special considerations with respect to supporting COST policies on promoting gender balance, enabling Early Career Investigators (ECI) and broadening geographical inclusiveness.

Venue

(For travel instructions, see below how to reach Tuorla.) The Science Centre Tuorla has been established to the premises of the Tuorla observatory in 2018. It is the place where the schools and public meet the scientists and it provides teaching to schools and to the teachers. The Science Centre is also an excellent place for small meeting and research schools. The site has several telescopes located around its main buildings and the one meter Dall-Kirkham reflector is the largest optical telescope in Finland. Since 2008, the Tuorla Planetarium has been operating next to the observatory. It is the departing point for the TimeTrek route (13.7 km) which portrays the whole history of the Universe, the Earth and the biosphere.

List of important dates

Dates to be noted include:
– Submit your application no later than: October 31, 2018 (but submit as soon as possible, since the candidate selection is performed until the quota is filled)
– Candidate selection: within a week after submission (until the quota is filled)
– Training School: Nov.26-Dec.1, 2018

Selection Criteria

Candidates will be evaluated based on their proposed research project and their motivation letter. However, there will be special considerations with respect to supporting COST policies on promoting gender balance, enabling Early Career Investigators (ECI) and broadening geographical inclusiveness.

Challenges and general goals of the Training School

Challenges are similar in astronomy and Earth Observation, with signal processing, statistics, machine learning, and computer science as the common denominator. BigSkyEarth Training Schools aim at boosting the communication within and between disciplines and applications areas by propagating and advancing relevant common solutions developed within Big Data analysis and management research and industrial environments.
Their goal is to contribute with a valuable know-how encompassing from sensor and data modelling, features extraction and metadata, information representation, data structures, pattern recognition, statistical/machine learning, data analytics, advanced visualisation, to data mining and KDD. Besides, specific computer science topics will be addressed as particular programming techniques, data structures in large databases, cloud computing, and related topics. Their key aspect is addressing all these topics in synergy to set in a logical interdisciplinary framework building bridges between diverse areas.

Topics and general programme

The school will cover a wide range of topics:

  • Machine learning applied on topics such as finding bars in big simulations (e.g. Illustris)
  • Classical Machine Learning vs. Deep Learning
    • Representation Learning
    • Convolutional Networks
  • Supervised, Unsupervised, Reinforcement Learning, …
    • Classification
    • Regression
  • Astronomical Application Examples
    • Star/Galaxy Classification
    • Transient Classification
    • Transient Detection
    • De-blending
  • What is the network learning?
  • The principal components analysis and its application to spectra
  • Bayesian filtering and smoothing

Traveling to Tuorla

The Science Centre Tuorla is located on the south-western coast of Finland, 150 km west of Helsinki. It is located close to the city of Turku which one can reach by air, sea, road and rail.

What is BigSkyEarth?

With the current emergence of Terabyte(TB)-scale astronomical and Earth observation systems, the traditional approach to basic functions such as data searching, analytics or visualization are becoming increasingly difficult to handle. Simple database queries can result now in data subsets so large that they are incomprehensible, slow (or even impossible) to handle, and impossible to visualize with commodity visualization tools. Astronomy and remote sensing complement each other, as they are on the quest for new Big Data interpretation capabilities: both disciplines have peculiar data, typical data processing and analysis chains, and specific models to be fed with data. However, both disciplines lack the capabilities for easily accessible semantics-oriented browsing (usage of higher level descriptive expressions) in large data archives. Therefore, joint efforts to design and develop innovative Big Data tools should help users in many different fields and set new standards for many communities. This has identified several broad challenges to this line of reasoning that need multidisciplinary approach through international networking of experts and professionals. These challenges are then channelled into Action Objectives:
– Challenge A: Digital curation and data access
– Challenge B: New frontiers in visualisation
– Challenge C: Adaptation to new high performance computing (HPC) technologies
– Challenge D: New generation of scientists in the age of interdisciplinarity
