StarGAN-VC++: Towards Emotion Preserving Voice Conversion Using Deep Embeddings

1 code implementation14 Sep 2023 Arnab Das, Suhita Ghosh, Tim Polzehl, Sebastian Stober

In this paper, we show that StarGANv2-VC fails to disentangle the speaker and emotion representations, pertinent to preserve emotion.

Dual Branch Prior-SegNet: CNN for Interventional CBCT using Planning Scan and Auxiliary Segmentation Loss

1 code implementation11 May 2022 Philipp Ernst, Suhita Ghosh, Georg Rose, Andreas Nürnberger

This paper proposes an extension to the Dual Branch Prior-Net for sparse view interventional CBCT reconstruction incorporating a high quality planning scan.

Predictive coding, precision and natural gradients

no code implementations12 Nov 2021 Andre Ofner, Raihan Kabir Ratul, Suhita Ghosh, Sebastian Stober

Here we focus on the related, but still largely under-explored connection between precision weighting in predictive coding networks and the Natural Gradient Descent algorithm for deep neural networks.

Uncertainty-Aware Temporal Self-Learning (UATS): Semi-Supervised Learning for Segmentation of Prostate Zones and Beyond

no code implementations8 Apr 2021 Anneke Meyer, Suhita Ghosh, Daniel Schindele, Martin Schostak, Sebastian Stober, Christian Hansen, Marko Rak

Various convolutional neural network (CNN) based concepts have been introduced for the prostate's automatic segmentation and its coarse subdivision into transition zone (TZ) and peripheral zone (PZ).
