Human-AI Interaction Design in Machine Teaching

no code implementations10 Jun 2022 Karan Taneja, Harshvardhan Sikka, Ashok Goel

Machine Teaching (MT) is an interactive process where a human and a machine interact with the goal of training a machine learning model (ML) for a specified task.

ReFace: Real-time Adversarial Attacks on Face Recognition Systems

no code implementations9 Jun 2022 Shehzeen Hussain, Todd Huster, Chris Mesterharm, Paarth Neekhara, Kevin An, Malhar Jere, Harshvardhan Sikka, Farinaz Koushanfar

We find that the white-box attack success rate of a pure U-Net ATN falls substantially short of gradient-based attacks like PGD on large face recognition datasets.

A Closer Look at Disentangling in $β$-VAE

no code implementations11 Dec 2019 Harshvardhan Sikka, Weishun Zhong, Jun Yin, Cengiz Pehlevan

In many data analysis tasks, it is beneficial to learn representations where each dimension is statistically independent and thus disentangled from the others.
