Protect Your Score: Contact Tracing With Differential Privacy Guarantees

no code implementations18 Dec 2023 Rob Romijnders, Christos Louizos, Yuki M. Asano, Max Welling

The pandemic in 2020 and 2021 had enormous economic and societal consequences, and studies show that contact tracing algorithms can be key in the early containment of the virus.

Impact of Aliasing on Generalization in Deep Convolutional Networks

no code implementations ICCV 2021 Cristina Vasconcelos, Hugo Larochelle, Vincent Dumoulin, Rob Romijnders, Nicolas Le Roux, Ross Goroshin

We investigate the impact of aliasing on generalization in Deep Convolutional Networks and show that data augmentation schemes alone are unable to prevent it due to structural limitations in widely used architectures.

Data Selection for training Semantic Segmentation CNNs with cross-dataset weak supervision

no code implementations16 Jul 2019 Panagiotis Meletis, Rob Romijnders, Gijs Dubbelman

Training convolutional networks for semantic segmentation with strong (per-pixel) and weak (per-bounding-box) supervision requires a large amount of weakly labeled data.

A Domain Agnostic Normalization Layer for Unsupervised Adversarial Domain Adaptation

no code implementations14 Sep 2018 Rob Romijnders, Panagiotis Meletis, Gijs Dubbelman

We show that conventional normalization layers worsen the performance of current Unsupervised Adversarial Domain Adaption (UADA), which is a method to improve network performance on unlabeled datasets and the focus of our research.

Applying Deep Learning to Basketball Trajectories

1 code implementation12 Aug 2016 Rajiv Shah, Rob Romijnders

Using a dataset of over 20, 000 three pointers from NBA SportVu data, the models based simply on sequential positional data outperform a static feature rich machine learning model in predicting whether a three-point shot is successful.
