National Science Foundation grant to fund study of measuring emotions with cybersystems

MANHATTAN — Emotions can heavily influence decision-making. To study the scope of this influence, a necessary first step is the ability to measure a person’s emotional state. A project at Kansas State University has been recently funded by the National Science Foundation to develop and improve devices used for this purpose.

David Thompson, assistant professor in the Mike Wiegers Department of Electrical and Computer Engineering has been awarded nearly $500,000 by the National Science Foundation’s Information and Intelligent Systems: Core Programs for his project “Enhancing EEG-based Emotion Estimation with Transfer Learning, Priming and Virtual Reality.”

The Information and Intelligent Systems: Core Programs is part of the NSF’s Division of Information and Intelligent Systems, which supports research and education projects that develop new knowledge in three core programs: cyber-human systems, information integration and informatics, and robust intelligence.

Thompson’s project, funded under the Cyber-Human Systems Program, will lay the groundwork for devices that can be used outside the laboratory, from classrooms to theme parks.

“The normal way to measure emotion is by simply asking the person, but that takes time, causes interruptions and leads to false reports,” Thompson said.

His research will consist of applying three techniques — transfer learning, semantic priming and virtual reality — to increase the performance and reliability of these emotion-measuring systems. A collaboration with Thinkwell, a global entertainment company, will also be included in the project.

Together, these investigations are expected to dramatically improve the performance and, critically, the cross-task reliability of these systems.

“Emotion affects nearly every field of human study,” Thompson said. “Real-time measurement of valid emotions has the potential to cause cross-disciplinary transformation.”

The project will support significant undergraduate and graduate research efforts of students from all backgrounds in the Carl R. Ice College of Engineering at Kansas State University, enriching the educational experience of all participants.

New transmission model for Ebola predicted Uganda cases

MANHATTAN — A new risk assessment model for the transmission of Ebola accurately predicted its spread into the Republic of Uganda, according to the Kansas State University researchers who developed it.

Caterina Scoglio, professor, and Mahbubul Riad, doctoral student, both in the Mike Wiegers Department of Electrical and Computer Engineering in the Carl R. Ice College of Engineering at Kansas State University; Musa Sekamatte and Issa Makumbi at Uganda Ministry of Health; and Felix Ocom with the World Health Organization in Uganda, published “Risk assessment of Ebola virus disease spreading in Uganda using a multilayer temporal network” in bioRxiv on May 23.

The paper describes a new model to better predict how diseases like Ebola spread. The model combines data of people’s constant contacts — such as family members and co-workers — with their temporary contacts — such as people in a market or encountered during travel. According to Scoglio, the model should be used as a risk assessment tool to prepare and distribute resources, but it also has been accurate thus far regarding the movement of Ebola from the Democratic Republic of Congo into Uganda.

“This is very a new type of model,” Scoglio said. “Since we consider movement data in addition to constant contacts, we saw that not only are the districts directly bordering Congo at risk but that the districts on the path to some important Ugandan destinations also are at risk.”

In 2018, Scoglio and her collaborators worked with Ugandan officials to collect movement data to model disease progression and find areas most at risk. According to the model, the Kasese district was the highest risk area for an infected person to enter the country. The researchers used the model to create a 150-day simulation of possible disease progression in Uganda and produced a map of 23 Ugandan districts at risk.

The specific scenario used in the simulation is similar to actual events so far. According to the Uganda Health Ministry’s June 18 release, there are three confirmed cases of Ebola in travelers to Uganda — all from one family that entered the country at the Kasese district border.

“The risk assessment maps can be used to allocate and distribute limited resources,” Scoglio said. “Uganda has about 4,000 doses of the new Ebola vaccine. They are vaccinating health workers, communicating about how to prevent spreading diseases, and advising people to limit travel in high-risk areas. We have much respect and admiration for how Uganda has organized the preparedness and now the response.”

The researchers used the simulation of Ebola in Uganda to test their model because there is a lot of traffic coming into the country from the Democratic Republic of Congo for health care, trading and refuge. Ebola is highly contagious through physical contact with an infected person and their bodily fluids.

Scoglio said that even though the real events in Uganda have aligned with the simulated model, the scenario should only be used to mitigate the risk.

“One very important point for the public to understand is the concept of risk and probability with these maps,” Scoglio said. “It should not be interpreted that these red regions will be affected because that will cause panic in the population, but rather these are a guide for allocation of limited resources in regions that could be potentially affected if no mitigations are implemented.”

This model may open a new era in infectious disease management, Scoglio said. She gives credit to Aram Vajdi, doctoral student in electrical and computer engineering at Kansas State University, for developing the framework for the theoretical model based on a multilayer temporal network and the Gillespie algorithm. Scoglio also praised Riad, who applied the data collected from Uganda and how Ebola was transmitted to create the risk assessment.

According to Scoglio, network models used for highly infectious disease risk assessment must be able to anticipate changes in human-to-human contacts — unlike many other models, which are based mainly on constant contacts and constant movement flows. Using these models can help increase the effectiveness of preventive measures by targeting the most critical regions and can help decrease the risk of Ebola and other infectious diseases from spreading.
