How to help humans understand robots
Scientists who study human-robot interaction often focus on understanding human intentions from a robot’s perspective, so the robot learns to cooperate with people more effectively. But human-robot interaction is a two-way street, and the human also needs to learn how the robot behaves. Thanks to decades of cognitive science and educational psychology research, scientists have […]
Injecting fairness into machine-learning models
If a machine-learning model is trained using an unbalanced dataset, such as one that contains far more images of people with lighter skin than people with darker skin, there is serious risk the model’s predictions will be unfair when it is deployed in the real world. But this is only one part of the problem. […]
A security technique to fool would-be cyber attackers
Multiple programs running on the same computer may not be able to directly access each other’s hidden information, but because they share the same memory hardware, their secrets could be stolen by a malicious program through a “memory timing side-channel attack.” This malicious program notices delays when it tries to access a computer’s memory, because […]
Can machine-learning models overcome biased datasets?
Artificial intelligence systems may be able to complete tasks quickly, but that doesn’t mean they always do so fairly. If the datasets used to train machine-learning models contain biased data, it is likely the system could exhibit that same bias when it makes decisions in practice. For instance, if a dataset contains mostly images of […]
