Data regularized q
WebWe report experimental results using the photo-realistic Gibson benchmark dataset in the AI Habitat 3D simulation environment to demonstrate that our framework substantially improves performance on standard measures in comparison with state of the art baseline. Video Citation Acknowledgements WebMay 20, 2024 · The aim of this paper is to provide new theoretical and computational understanding on two loss regularizations employed in deep learning, known as local entropy and heat regularization. For both regularized losses, we introduce variational characterizations that naturally suggest a two-step scheme for their optimization, based …
