Þorsteinn Elí Gíslason, computational engineering student at the University of Iceland, has recently been involved in an extensive and highly complex collaboration between NASA, the University of Iceland, JSC (the Jülich Supercomputing Centre) and the tech giant IBM. Much of the work on the project took place in Huntsville, Alabama, but contributions were also made in Brazil, the UK, Switzerland and Germany. The project focuses on remote sensing, a subject in which the University of Iceland is a global leader. Jón Atli Benediktsson, Rector of UI and professor of electrical engineering, is in fact one of the world’s leading scientists in the field.
Elí worked on the cutting-edge project with a team at NASA to develop an AI model capable of working with highly complex remote sensing data. Remote sensing involves, for example, taking digital images from planes and satellites and using these to extract data about the Earth's surface.
Elí explains that this project builds on the basic models already developed by NASA and IBM. The goal is to further develop these models in order to train them to understand remote sensing images gathered by satellites. Such images are often complex and of limited resolution. According to Elí, the aim of the project is to develop a model that, with additional training, will be fully capable of identifying specific features in remote sensing images. For example, locating wildfire damage.
The model is based on AI technology and is designed to reduce the time needed to specialise the model for each specific task.
“Instead of having a model that knows nothing to start with, and needing to teach the model to recognise images and understand which parts are important, we should end up with a model where we have already done that prep work. Then the model just needs to learn the specific knowledge required for each specialised application,” explains Elí.
Using supercomputing facilities
In order to develop these kinds of solutions, supercomputing facilities are required, which is where JSC comes in. “JSC is providing us with access to supercomputing facilities and their systems to train the models and conduct experiments.”
Elí explains that the team he has been working with in Huntsville is called NASA IMPACT. The team has grown rapidly in the past few years. “Near the end of my time there, we were told that NASA was planning to change the name of the team and reorganise it to make it stronger and allow faster expansion, so that they would be able to take on more and larger projects.”
“My stay was a kind of preliminary trial for the partnership between UI and NASA IMPACT. We hope that it will lead to further collaboration between the two institutions, which will create more opportunities for students like me.”
