FOLEY SCHOLARS

 

Battling opioid addiction through computation and community

Foley Scholar Stevie Chancellor, advised by Munmun De Choudhury, researches computational methods to understand irregular behaviors in online communities with a focus on mental health challenges like pro-eating disorder, opioid addiction, and suicidal ideation.

She is currently analyzing behaviors around “deviant” recovery from opioid addiction on Reddit. As opioid abuse continues to worsen, some addicts turn to clinically unverified recovery methods to ameliorate the symptoms of withdrawal. Her team is blending computational techniques and conducting interviews to identify opioid recovery behaviors across a large group of drug subreddits and then pinpoint substances that are used for deviant recovery behaviors.

Developing an offline Internet in low-resource environments

A pervasive assumption says that Internet access is determined by wires or wireless signals that deliver information from a computer network and onto your hard drive in a matter of seconds. The Cuban “Offline Internet” defies this convention with its robust, human-driven, media-distribution network powered often times by simple USB drives.

Foley Scholar Michaelanne Dye, advised by Amy Bruckman and Neha Kumar, outlines how this network, El Paquete Semanal, is shaping the Cuban media culture and what it may mean for other low-resource environments in being able to gain Internet access.

Stroke victims could gain a new path to mobility

Potentially life-altering improvements in mobility for stroke victims could be around the corner thanks to research by Foley Scholar Caitlyn Seim. Pioneering work from Thad Starner’s lab in passive haptic learning allows users to wear a motorized glove and learn new skills, like piano music or Braille, as the glove taps out vibration sequences on each finger, all while the user is occupied with other tasks such as email or driving. Seim is currently developing the tech for stroke patients to help them regain a measure of mobility in their affected limbs. Learn more about her approach and view a heart-warming video of real-life patients she is helping.

FOLEY SCHOLAR FINALISTS

 

Making AIs 'see' better for image content recognition

Foley Scholar Finalist Aishwarya Agrawal, advised by Dhruv Batra, is developing the foundation for artificial intelligence systems that can ‘see’ or understand the contents of an image and communicate that information to humans in free-form natural language. It’s simple for humans to describe what’s in a photo, but computer systems have a much harder time. Agrawal and a research team have developed the Grounded Visual Question-Answering model to advance AI capabilities in describing image scenes. Applications in society are wide-ranging and could benefit households and workplaces in the near future by leveraging current voice-assisted AI technologies.

AIs can now create games on their own

Foley Scholar Finalist Matthew Guzdial's journey in game development and research has spanned almost a decade and two degree programs at Georgia Tech. He's now reinventing how artificially intelligent agents approach creating video games. Guzdial, advised by Mark Riedl, has developed machine-learning methods that can create Atari-era looking games and play like your classic platformers (Mario, Mega Man, etc). These are the first machine-learning algorithms capable of developing a full gaming experience without human input according to the researchers.

Take an interactive tour highlighting Guzdial's gaming journey.

 

 

 

In the pursuit of 'CS for All,' a possible new pathway

Foley Scholar Finalist Miranda Parker, advised by Mark Guzdial, explores questions of access to computer science and researches the influences on and barriers to computing education to better inform future policy and outreach. In order to create ""Computer Science for All,"" she is seeking to understand what works and what doesn't for a multitude of groups, particularly those at schools that are characterized by high levels of low-socioeconomic, minority, or under-achieving students. 

Her recent research suggests an important new finding in this space: Students with higher socioeconomic status (SES) may not necessarily perform better than lower-SES students in computer science because of more CS access, but rather because of better spatial ability skills, those skills used for common tasks such as navigation, measuring distances, or for technical aptitude. Spatial abilities can be taught in the classroom at lower costs, thereby marking a possible opportunity for improved CS achievement for lower-SES students and minorities.

Developing a mindset for building unbiased software

Software has been shown to discriminate against certain groups and Foley Scholar Finalist Ari Schlesinger, advised by Beki Grinter and Keith Edwards, is researching ways enterprises can operationalize strategies to support software development with fairness in mind. Her work focuses on how complex social problems become embedded in technical systems—like AI algorithms and frameworks—and what steps people can take to design computing technologies that do better. Schlesinger’s recent work shows how AI chatbots have a hard time discussing race and how they might handle race in new and improved ways.

Visual analytics technique gives users more control over data

Foley Scholar Finalist Emily Wall is using visual analytics to help users make the most out of the information they have available. She and a team of researchers propose that cognitive biases influence user exploration of data in ways that are measurable through user interactions. The team, including advisor Alex Endert, developed metrics to systematically detect and quantify bias from user interactions and make users aware of bias processes throughout their analyses.

One real-world application: car or home buyers may dismiss certain options based on, for example, fuel economy for cars or location for homes, but Wall's visual analytics approach can measure users' preferences based on their interactions with the data, direct users to new data points, and make that next big purchase that much easier.
