An Indian-American computer science professor, Pavithra Prabhakar at a US university has received an Amazon Research Award for designing a tool that minimises negative user experiences. This tool will help the design teams make crucial decisions regarding the user experience.
Pavithra Prabhakar was one of 74 recipients of the awards from Amazon, which also includes access to more than 300 Amazon public datasets and Amazon Web Services AI and Machine Learning services and tools.
She is currently working as a programme director at the National Science Foundation while on sabbatical from K-State.
“The broad objective of the project is to automatically characterise how much two versions of machine learning-based systems are similar or different,” Prabhakar said.
“These systems are regularly retrained to achieve superior performance; however, this does not often translate to a better user experience. This can be mitigated by equipping the design team with an automated tool that could highlight where and by how much the systems changed between different versions, thereby aiding the team in making decisions regarding the acceptability of the changes from a user experience perspective,” she added.
The proposed study will rely on fundamental ideas from control theory and process algebra to describe mathematical conceptions of the distance between various machine learning system versions and provide algorithms for determining their similarity and dissimilarity. Design teams will gain from this automated tool to help them make essential judgments about enhancing the usability of machine learning-based intelligent software systems.
The proposed research will build on foundational concepts from process algebra and control theory to define mathematical notions of distance between different versions of machine learning systems and develop algorithms for outputting the similarity and dissimilarity between them.
Earlier, she was recognised with several awards, including the NSF CAREER award, the Office of Naval Research Young Investigator Award, and the Marie Curie Career Integration Grant from the European Union.
