Autor: Papoutsellis, Evangelos, da Costa-Luis, Casper, Deidda, Daniel, Delplancke, Claire, Duff, Margaret, Fardell, Gemma, Gillman, Ashley, Jørgensen, Jakob S., Kereta, Zeljko, Ovtchinnikov, Evgueni, Pasca, Edoardo, Schramm, Georg, Thielemans, Kris

We introduce a stochastic framework into the open--source Core Imaging Library (CIL) which enables easy development of stochastic algorithms. Five such algorithms from the literature are developed, Stochastic Gradient Descent, Stochastic Average Grad

Stability of the regular $n$-gon rotating equilibria with logarithm interaction

Autor: Muscas, Anna-Monika, Pasca, Daniel, Stoica, Cristina

We study the linear stability of regular $n$-gon rotating equilibria in the $n$-body problem with logarithm interaction. In the presence of a central mass $M$, linear stability is insured if $M$ is bounded below and above by constants depending on th

A directional regularization method for the limited-angle Helsinki Tomography Challenge using the Core Imaging Library (CIL)

Autor: Jørgensen, Jakob Sauer, Papoutsellis, Evangelos, Murgatroyd, Laura, Fardell, Gemma, Pasca, Edoardo

This article presents the algorithms developed by the Core Imaging Library (CIL) developer team for the Helsinki Tomography Challenge 2022. The challenge focused on reconstructing 2D phantom shapes from limited-angle computed tomography (CT) data. Th

Abstract Clonal hematopoiesis of indeterminate potential is the primary pathogenic risk factor for myeloid neoplasms, while heteroplasmy (mutations in a subset of cellular mitochondrial DNA) is another marker of clonal expansion associated with hemat

Summarize the Past to Predict the Future: Natural Language Descriptions of Context Boost Multimodal Object Interaction Anticipation

Autor: Pasca, Razvan-George, Gavryushin, Alexey, Hamza, Muhammad, Kuo, Yen-Ling, Mo, Kaichun, Van Gool, Luc, Hilliges, Otmar, Wang, Xi

We study object interaction anticipation in egocentric videos. This task requires an understanding of the spatio-temporal context formed by past actions on objects, coined action context. We propose TransFusion, a multimodal transformer-based archite
