DESCRIPTION:Abstract\nIn this talk\, I present a multipronged strategy for
zero-shot cross-lingual Information Extraction\, that is the construction
of an IE model for some target language\, given existing annotations exclu
sively in some other language. This work is part of the JHU team’s effort
under the IARPA BETTER program. I explore data augmentation techniques inc
luding data projection and self-training\, and how different pretrained en
coders impact them. We find through extensive experiments and extension of
techniques that a combination of approaches\, both new and old\, leads to
better performance than any one cross-lingual strategy in particular.\nBi

DESCRIPTION:Abstract\nOne of the keys to success in machine learning applic
ations is to improve each user’s personal experience via personalized mode
ls. A personalized model can be a more resource-efficient solution than a
general-purpose model\, too\, because it focuses on a particular sub-probl
em\, for which a smaller model architecture can be good enough. However\,
training a personalized model requires data from the particular test-time
user\, which are not always available due to their private nature and tech
nical challenges. Furthermore\, such data tend to be unlabeled as they can
be collected only during the test time\, once after the system is deploye
d to user devices. One could rely on the generalization power of a generic
model\, but such a model can be too computationally/spatially complex for
real-time processing in a resource-constrained device. In this talk\, I w
ill present some techniques to circumvent the lack of labeled personal dat
a in the context of speech enhancement. Our machine learning models will r
equire zero or few data samples from the test-time users\, while they can
still achieve the personalization goal. To this end\, we will investigate
modularized speech enhancement models as well as the potential of self-sup
ervised learning for personalized speech enhancement. Because our research
achieves the personalization goal in a data- and resource-efficient way\,
it is a step towards a more available and affordable AI for society.\nBio
