> Title:
> Are hallucinations in text generation always undesirable? A perspective
> from text elaboration
>
> Abstract:
> Recent developments in deep learning have led to exponential improvements
> in Natural Language Generation (NLG), particularly in terms of fluency and
> coherency. On the other hand, deep learning-based text generation is also
> susceptible to hallucinating unintended text that is not directly
> supported by the source document. These unsupported texts are called
> hallucinations and are often perceived as undesirable. In this talk, we
> investigate whether hallucinations are always undesirable through the lens
> of text summarization and simplification. Surprisingly, we show that many
> of these unsupported generations provide background knowledge for
> comprehension. In fact, although the primary tool for summarization and
> the implication is content reduction, content addition (aka elaborative
> generation) may also be beneficial for many real-world applications.

> Sponsored by the UCR Data Science Center, the purpose of the Data Science
> Seminars is to foster collaborations between "core" Data Science faculty
> (from CSE/ECE/Stat Departments) and faculty/visitors from other sciences
> that face Data Science problems in their research. These informal
> gatherings are open to interested faculty and graduate students. Each
> meeting will start with a talk describing research problems and then a
> discussion will follow for questions, open problems, ideas for possible
> collaborations etc.

> Please forward this email to other colleagues or graduate students in your
> lab that may be interested. Moreover, if you are interested in giving a
> Data Science related talk, please contact me.
