Center for Language and Speech Processing Spring Seminar Series: Alessandra Cervone

Description

Alessandra Cervone, an applied scientist at Amazon Alexa AI, will present a talk titled "Controllable Text Generation for Creative Applications" as part of the Center for Language and Speech Processing Spring Seminar Series.

Abstract:

Recent advances in large pretrained language models have unlocked new exciting applications for Natural Language Generation for creative tasks, such as lyrics or humour generation. In this talk we will discuss recent works by our team at Alexa AI and discuss current challenges: (1) Pun understanding and generation: We release new datasets for pun understanding and the novel task of context-situated pun generation, and demonstrate the value of our annotations for pun classification and generation tasks. (2) Song lyric generation: we design a hierarchical lyric generation framework that enables us to generate pleasantly-singable lyrics without training on melody-lyric aligned data, and show that our approach is competitive with strong baselines supervised on parallel data. (3) Create with Alexa: a multimodal story creation experience recently launched on Alexa devices, which leverages story text generation models in tandem with story visualization and background music generation models to produce multimodal stories for kids.
