*Title:*        Advances and Limitations in Generalization via
Self-Supervised Pretrained Representations

*Abstract: * Pretrained neural representations, learned from unlabeled
text, have recently led to substantial improvements across many natural
language problems. Yet some components of these models are still brittle
and heuristic, and sizable human labeled data is typically needed to obtain
competitive performance on end tasks.

I will first talk about recent advances from our team leading to (i)
improved multi-lingual generalization and ease of use through
tokenization-free pretrained representations and (ii) better few-shot
generalization for underrepresented task categories via neural language
model-based example extrapolation. I will then point to limitations of
generic pre-trained representations when tasked with handling both language
variation and out-of-distribution compositional generalization, and the
relative performance of induced symbolic representations.

*Bio: *Kristina Toutanova is a research scientist at Google Research in
Seattle and an affiliate faculty at the University of Washington. She
obtained her Ph.D. from the Computer Science Department at Stanford
University with Christopher Manning, and her MSc in Computer Science from
Sofia University, Bulgaria. Prior to joining Google in 2017, she was a
researcher at Microsoft Research, Redmond. Kristina focuses on modeling the
structure of natural language using machine learning, most recently in the
areas of representation learning, question answering, information retrieval
and semantic parsing. Kristina is a past co-editor in chief of TACL, a
program co-chair for ACL 2014, and a general chair for NAACL 2021.
