Text is All You Need: Personalizing ASR Models using Controllable Speech Synthesis

no code implementations27 Mar 2023 Karren Yang, Ting-yao Hu, Jen-Hao Rick Chang, Hema Swetha Koppula, Oncel Tuzel

Here, we ask two fundamental questions about this strategy: when is synthetic data effective for personalization, and why is it effective in those cases?

Style Equalization: Unsupervised Learning of Controllable Generative Sequence Models

no code implementations6 Oct 2021 Jen-Hao Rick Chang, Ashish Shrivastava, Hema Swetha Koppula, Xiaoshuai Zhang, Oncel Tuzel

However, under an unsupervised-style setting, typical training algorithms for controllable sequence generative models suffer from the training-inference mismatch, where the same sample is used as content and style input during training but unpaired samples are given during inference.

Learning Human Activities and Object Affordances from RGB-D Videos

no code implementations4 Oct 2012 Hema Swetha Koppula, Rudhir Gupta, Ashutosh Saxena

Given a RGB-D video, we jointly model the human activities and object affordances as a Markov random field where the nodes represent objects and sub-activities, and the edges represent the relationships between object affordances, their relations with sub-activities, and their evolution over time.
