*Title*: Towards Generalizable and Robust Neural Machines for Visual
Learning

*Abstract*:
The past several years have seen a growing demand for building intelligent
machines that can learn from and generalize to complex visual cues.
However, despite tremendous performance improvements, high-capacity models
such as deep neural networks still struggle to generalize to the diverse
visual world. In this talk, I will present my recent work addressing
challenges on learning more generalizable and robust visual
representations. This requires machine learning models to not only classify
data accurately from known classes and distributions, but also to develop
robustness against abnormal examples in open environments. To this end, I
will first talk about works on how we can improve generalization by
leveraging multiple learning agents. Then, I will discuss an approach that
effectively detects anomalies from outside the training distribution.
Finally, I will share ongoing efforts on learning highly generalizable
representations without strong human supervision, followed by discussion of
future directions towards a minimally supervised, continuous learning
paradigm.

*Bio*:
Yixuan (Sharon) Li is a Research Scientist at Facebook AI. Her research
interests are in machine learning and representation learning, with
applications to computer vision and network science. She received her Ph.D.
from Cornell University in 2017, where she was advised by John E. Hopcroft,
Kilian Q. Weinberger and Thorsten Joachims. Prior to Cornell, she obtained
her B.Eng from the honored class of Shanghai Jiaotong University in 2013.
She was selected as one of the *Rising Stars in EECS *by Stanford
University in 2017. She is the recipient of ACM-W Scholarship, D.E.Shaw
Exploration Fellowship and Cornell Graduate Research Fellowship.
