Dynamic Probabilistic Pruning: A general framework for hardware-constrained pruning at different granularities

no code implementations26 May 2021 Lizeth Gonzalez-Carabarin, Iris A. M. Huijben, Bastiaan S. Veeling, Alexandre Schmid, Ruud J. G. van Sloun

Relevantly, the non-magnitude-based nature of DPP allows for joint optimization of pruning and weight quantization in order to even further compress the network, which we show as well.

Active Deep Probabilistic Subsampling

no code implementations1 Jan 2021 Hans van Gorp, Iris A.M. Huijben, Bastiaan S. Veeling, Nicola Pezzotti, Ruud Van Sloun

Subsampling a signal of interest can reduce costly data transfer, battery drain, radiation exposure and acquisition time in a wide range of problems.

Deep probabilistic subsampling for task-adaptive compressed sensing

1 code implementation ICLR 2020 Iris A. M. Huijben, Bastiaan S. Veeling, Ruud J. G. van Sloun

The field of deep learning is commonly concerned with optimizing predictive models using large pre-acquired datasets of densely sampled datapoints or signals.

Learning Sampling and Model-Based Signal Recovery for Compressed Sensing MRI

no code implementations22 Apr 2020 Iris A. M. Huijben, Bastiaan S. Veeling, Ruud J. G. van Sloun

Compressed sensing (CS) MRI relies on adequate undersampling of the k-space to accelerate the acquisition without compromising image quality.

How Good is the Bayes Posterior in Deep Neural Networks Really?

1 code implementation ICML 2020 Florian Wenzel, Kevin Roth, Bastiaan S. Veeling, Jakub Świątkowski, Linh Tran, Stephan Mandt, Jasper Snoek, Tim Salimans, Rodolphe Jenatton, Sebastian Nowozin

In this work we cast doubt on the current understanding of Bayes posteriors in popular deep neural networks: we demonstrate through careful MCMC sampling that the posterior predictive induced by the Bayes posterior yields systematically worse predictions compared to simpler methods including point estimates obtained from SGD.

Learning Sub-Sampling and Signal Recovery with Applications in Ultrasound Imaging

no code implementations15 Aug 2019 Iris A. M. Huijben, Bastiaan S. Veeling, Kees Janse, Massimo Mischi, Ruud J. G. van Sloun

Compressed sensing emerged as a popular framework for sparse signal reconstruction from a small set of compressed measurements.

Putting An End to End-to-End: Gradient-Isolated Learning of Representations

1 code implementation NeurIPS 2019 Sindy Löwe, Peter O'Connor, Bastiaan S. Veeling

We propose a novel deep learning method for local self-supervised representation learning that does not require labels nor end-to-end backpropagation but exploits the natural order in data instead.

Predictive Uncertainty through Quantization

no code implementations12 Oct 2018 Bastiaan S. Veeling, Rianne van den Berg, Max Welling

High-risk domains require reliable confidence estimates from predictive models.

Sample Efficient Semantic Segmentation using Rotation Equivariant Convolutional Networks

no code implementations2 Jul 2018 Jasper Linmans, Jim Winkens, Bastiaan S. Veeling, Taco S. Cohen, Max Welling

The group equivariant CNN framework is extended for segmentation by introducing a new equivariant (G->Z2)-convolution that transforms feature maps on a group to planar feature maps.

Rotation Equivariant CNNs for Digital Pathology

4 code implementations8 Jun 2018 Bastiaan S. Veeling, Jasper Linmans, Jim Winkens, Taco Cohen, Max Welling

We propose a new model for digital pathology segmentation, based on the observation that histopathology images are inherently symmetric under rotation and reflection.

Towards radiologist-level cancer risk assessment in CT lung screening using deep learning

no code implementations5 Apr 2018 Stojan Trajanovski, Dimitrios Mavroeidis, Christine Leon Swisher, Binyam Gebrekidan Gebre, Bastiaan S. Veeling, Rafael Wiemker, Tobias Klinder, Amir Tahmasebi, Shawn M. Regis, Christoph Wald, Brady J. McKee, Sebastian Flacke, Heber MacMahon, Homer Pien

Importance: Lung cancer is the leading cause of cancer mortality in the US, responsible for more deaths than breast, prostate, colon and pancreas cancer combined and it has been recently demonstrated that low-dose computed tomography (CT) screening of the chest can significantly reduce this death rate.
