Differences in Visual Perception in Humans and Deep Neural Networks

Ben Henrik Lönnqvist

Visual grouping is the ability to combine parts of objects to form whole objects, and it is crucial for general and robust vision. Despite this, a comprehensive model of how the process works in humans remains elusive. In my thesis, I investigate how well ...

Path and Intersections: Characterization of Quasi-metrics in Directed Okamura-Seymour Instances

Yu Chen

We study the following distance realization problem. Given a quasi-metric D on a set T of terminals, does there exist a directed Okamura-Seymour graph that realizes D as the (directed) shortest-path distance metric on T? We show that, if we are further giv ...

Hierarchical Training of Deep Neural Networks Using Early Exiting

Pascal Frossard, Liza Carol Andrea Dunbar, Ahmet Caner Yüzügüler, Yamin Sepehri

Deep neural networks (DNNs) provide state-of-the-art accuracy for vision tasks, but they require significant resources for training. Thus, they are trained on cloud servers far from the edge devices that acquire the data. This issue increases communication ...

Automated fiducial-based alignment of cryo-electron tomography tilt series in Dynamo

Henning Paul-Julius Stahlberg

With the advent of modern technologies for cryo-electron tomography (cryo-ET), high-quality tilt series are more rapidly acquired than processed and analyzed. Thus, a robust and fast-automated alignment for batch processing in cryo-ET is needed. While diff ...
