My name is Arthur Bražinskas, I’m a Research Scientist at Google working on natural language generation for Google Assistant. My (submitted) Ph.D. at the University of Edinburgh was on low- and high-resource opinion summarization. I was fortunate to be part of the ILCC group at the University of Edinburgh and supervised by Ivan Titov and Mirella Lapata.
I focus on low-resource settings where annotated datasets are scarce yet large amounts of unannotated data is available. In these settings, a model learns a task without direct supervision or from a few examples. My research is driven by practical problems and the interplay of theory and practice.
On the machine learning side, I’m interested in Bayesian approaches that model data in terms of random/stochastic variables. These models can naturally capture uncertainty and represent information that is not directly observable in datasets. For training, my methods of choice are variational auto-encoders (VAE) and reinforcement learning.
I graduated (MSc. \w distinction) in artificial intelligence from the University of Amsterdam, Netherlands, where I specialized in theoretical machine learning and natural language processing. Before starting my Ph.D., I worked on machine learning modeling at Elsevier, Amazon, and Zalando. I also interned at Amazon under the supervision of R. Nallapati, M. Bansal, M. Dreyer.
