Explainable AI gets more human-centric — thanks to cognitive psychology

28 April 2022 Department of Computer Science , Faculty , Research , Feature , Artificial Intelligence

Imagine if Amazon Alexa could recommend a tub of ice cream or Siri could play a cheerful song if they hear sadness in your voice. AI voice recognition can now recognise emotions with very high accuracy. Yet it is not correct all the time, and this begs the question of how it make its decisions.

Walk, Watch, Learn: On-the-go video learning

20 April 2022 Department of Computer Science , Faculty , Research , Feature , Artificial Intelligence

 

As COVID crept across the world, confining people to their homes and chaining them to their desks — for work, school, and play — Zhao Shengdong was no exception. Involved in class after online class, the associate professor at NUS Computing and his PhD student Ashwin Ram soon began to wonder: What can we do to enhance the online learning experience? Instead of a static setting, could people learn dynamically on-the-go instead?

An AI that can read your emotions? Putting safeguards in place

21 January 2022 Department of Information Systems & Analytics , Faculty , Research , Feature , Artificial Intelligence

 

In recent years, some companies, including Amazon, JP Morgan, and Unilever, began asking prospective employees to do a curious thing — to film themselves answering a fixed set of questions. The firms would then run the videos through an AI-powered software, scanning faces and eye movements for signs of empathy, dependability, and other ‘desirable’ personality traits.

When Jungpil Hahn was appointed head of the Department of Information Systems and Analytics at NUS Computing in 2015, it changed his perspective on many things.

“I began to see the broader picture of the discipline as a whole, and began to think holistically about what we are teaching and what we are missing in the overall curriculum,” recalls Associate Professor Hahn. “That’s when I saw the urgency and extent of the problem.”

Bug-bane begone — enter the era of Automated Program Repair

22 October 2021 CSFEATURES Department of Computer Science , Faculty , Feature , Security

Consider a programmer sitting at her desk, trying to fix an error in a software system. First, she had to determine what was causing the problem and trace its source to a specific location within the programme’s code. Then she has to speculate on strategies that would fix the error, and test various patches to the code to see which one worked best. The entire process — called debugging — is an incredibly laborious and time-consuming process. It’s one that has vexed computer programmers for years, and continues to do so today.
