Transfer Learning for Segmentation Problems: Choose the Right Encoder and Skip the Decoder

no code implementations29 Jul 2022 Jonas Dippel, Matthias Lenga, Thomas Goerttler, Klaus Obermayer, Johannes Höhne

In this work, we investigate the impact of transfer learning for segmentation problems, being pixel-wise classification problems that can be tackled with encoder-decoder architectures.

Towards Fine-grained Visual Representations by Combining Contrastive Learning with Image Reconstruction and Attention-weighted Pooling

1 code implementation9 Apr 2021 Jonas Dippel, Steffen Vogler, Johannes Höhne

This paper presents Contrastive Reconstruction, ConRec - a self-supervised learning algorithm that obtains image representations by jointly optimizing a contrastive and a self-reconstruction loss.
