Physics-Informed Neural Network Policy Iteration: Algorithms, Convergence, and Verification

ICML 2024poster

Solving nonlinear optimal control problems is a challenging task, particularly for high-dimensional problems. We propose algorithms for model-based policy iterations to solve nonlinear optimal control problems with convergence guarantees. The main component of our approach is an iterative procedure…

Text-Free Image-to-Speech Synthesis Using Learned Segmental Units

ACL 2021long

In this paper we present the first model for directly synthesizing fluent, natural-sounding spoken audio captions for images that does not require natural language text as an intermediate representation or source of supervision. Instead, we connect the image captioning module and the speech synthesi…
