The mission of the QUVA-lab is to perform world-class research on deep vision. Such vision strives to automatically interpret with the aid of deep learning what happens where, when and why in images and video. Deep learning is a form of machine learning with neural networks, loosely inspired by how neurons process information in the brain. Research projects in the lab focus on learning to recognize objects in images from a single example, personalized event detection and summarization in video, and privacy preserving deep learning. The research is published in the best academic venues and secured in patents. Read the full blog post...
Our Projects
Adaptable Foundation Models
Danilo de Goede
Foundation models have established themselves as a revolutionary class of general-purpose AI models that provide impressive abilities to generate text, images, videos, and more. In this project, we study, develop, and evaluate new adaptive learning schemes throughout the foundation model lifecycle, covering pre-training, adaptation, and deployment.
Unsupervised Learning for Source Compression
Natasha Butt
Learned compression has seen recent advantages relative to traditional compression codecs. In this project, we will explore new methods for lossless and lossy compression with unsupervised learning.
Federated Learning
Rob Romijnders
Future of machine learning will see data distributed across multiple devices. This project studies effective model learning when data is distributed and communication bandwith between devices is limited.
Efficient Video Representation Learning
Mohammadreza Salehi
Despite the enormous advances of image representation learning, video representation learning has not been well explored yet because of the higher computational complexity and the space-time dynamics shaping the content of a video. In this research, we try to capture the content of a video more efficiently in different aspects such as data and computational efficiency.
Video Action Recognition
Pengwan Yang
In this project, we focus on video understanding with the goal of alleviating the dependency on labels. We develop methods that leveraging few-shot, weakly-supervised, and unsupervised learning signals.
Hardware-Aware Learning
Winfried van den Dool
We study and develop novel approaches for hardware-aware learning, focusing on actual hardware constraints, and work towards a unified framework for scaling and improving noisy and low-precision computing.
Generalizeable Video Representation Learning
Michael Dorkenwald
In this project we aim to develop self-supervised methods that obtain generalizeable video representations and solve novel tasks for which the usage of multiple modalities and is a necessity, such as video scene understanding.
Geometric Deep Learning
Gabriele Cesa
Many machine learning tasks come with some intrinsic geometric structure. In this project, we will study how to encode the geometry of a problem into neural-network architectures to achieve improved data efficiency and generalization. A particular focus will be given to 3D data and the task of 3D reconstruction, where the global 3D structure is only accessible through a number of 2D observations.
Previous Projects
Temporal Causality in Machine Learning
Phillip Lippe
Identifying causal relations beyond correlations from data is a key step towards generalization in deep learning. In this project we study and develop new methods to incorporate causal understanding in machine learning models and identify causal variables from high-dimensional observations, with a focus on temporal relations.
Harmonic Analysis for Stochastic Neural Networks
Adeel Pervez
Stochastic neural networks are widely used in probabilistic modeling but often have problems of instability. The type of stochasticity that can be usefully employed is also a limiting factor. In this project we apply harmonic analysis techniques to improve learning of stochastic models and to develop methods for efficient training of discrete stochastic models. Completed PhD thesis
Quantum Machine Learning
Evgenii Egorov
We develop the theory of quantum neural networks and its Bayesian formulation, and will construct quantum inspired classical deep learning models as a new class of classically efficient neural networks that use quantum statistics as inference model.
Symmetries and Causality
Pim de Haan
Most types of data possess symmetries and neural networks can be made to respect these. In this project, we are developing how to generalize there notions, introducing local symmetries, and explore connections between symmetries and interventions done to causal models.
Temporal modeling in videos
Amir Ghodrati
This project aims to learn representations able to maintain the sequential structure for video, for use cases in temporal video prediction tasks.
Fine-grained object recognition
Shuai Liao
Automatically recognize fine-grained categories with interactive accuracy by using very deep convolutional representations computed from automatically segmented objects and automatically selected features.
Personal event detection and recounting
Kirill Gavrilyuk
Automatically detect events in a set of videos with interactive accuracy for the purpose of personal video retrieval and summarization. We strive for a generic representation that covers detection, segmentation, and recounting simultaneously, learned from few examples.
Counting
Tom Runia
The goal of this project is to accurately count the number of arbitrary objects in an image and video independent of their apparent size, their partial presence, and other practical distractors. For use cases as in Internet of Things or robotics. Completed PhD thesis
Robust Mobile Tracking
Ran Tao
In an experimental view of tracking, the objective is to track the target’s position over time given a starting box in frame 1 or alternatively its typed category especially for long-term, robust tracking.
One shot visual instance search
Berkay Kıcanaoglu
Often when searching for something, a user will have available just 1 or very few images of the instance of search with varying degrees of background knowledge.
Statistical machine translation
Mert Kilickaya
The objective of this work package is to automatically generate grammatical descriptions of images that represent the meaning of a single image, based on the annotations resulting from the above projects. Completed PhD thesis
The story of this
Noureldien Hussein
Often when telling a story one is not interested in what happens in general in the video, but what happens to this instance (a person, a car to pursue, a boat participating in a race). The goal is to infer what the target encounters and describe the events that occur it. Completed PhD thesis
Distributed deep learning
Matthias Reisser
Future applications of deep learning will run on mobile devices and use data from distributed sources. In this project we will develop new efficient distributed deep learning algorithms to improve the efficiency of learning and to exploit distributed data sources.

Deep neural networks have a very large number of hyper-parameters. In this project we develop new methods to automatically and efficiency determine these hyperparameters from data for deep neural networks.
Symmetry adapted network architectures
Maurice Weiler
The training process of deep neural networks requires huge datasets which are expensive to collect. In this project we aim to improve the networks data efficiency by modeling domain adapted prior knowledge like symmetry properties of the data into the networks architectures.
