Unraveling the Temporal Dynamics of the Unet in Diffusion Models

no code implementations17 Dec 2023 Vidya Prasad, Chen Zhu-Tian, Anna Vilanova, Hanspeter Pfister, Nicola Pezzotti, Hendrik Strobelt

We propose an analytical method to systematically assess the impact of time steps and core Unet components on the final output.

Class-constrained t-SNE: Combining Data Features and Class Probabilities

1 code implementation26 Aug 2023 Linhao Meng, Stef van den Elzen, Nicola Pezzotti, Anna Vilanova

Data features and class probabilities are two main perspectives when, e. g., evaluating model results and identifying problematic items.

Neural Spherical Harmonics for structurally coherent continuous representation of diffusion MRI signal

no code implementations16 Aug 2023 Tom Hendriks, Anna Vilanova, Maxime Chamberland

We present a novel way to model diffusion magnetic resonance imaging (dMRI) datasets, that benefits from the structural coherence of the human brain while only using data from a single subject.

ProtoFold Neighborhood Inspector

no code implementations17 Oct 2022 Nicolas F. Chaves-de-Plaza, Klaus Hildebrandt, Anna Vilanova

Post-translational modifications (PTMs) affecting a protein's residues (amino acids) can disturb its function, leading to illness.

Incorporating Texture Information into Dimensionality Reduction for High-Dimensional Images

1 code implementation18 Feb 2022 Alexander Vieth, Anna Vilanova, Boudewijn Lelieveldt, Elmar Eisemann, Thomas Höllt

In this paper, we present a method for incorporating spatial neighborhood information into distance-based dimensionality reduction methods, such as t-Distributed Stochastic Neighbor Embedding (t-SNE).

GPGPU Linear Complexity t-SNE Optimization

1 code implementation28 May 2018 Nicola Pezzotti, Julian Thijssen, Alexander Mordvintsev, Thomas Hollt, Baldur van Lew, Boudewijn P. F. Lelieveldt, Elmar Eisemann, Anna Vilanova

The t-distributed Stochastic Neighbor Embedding (tSNE) algorithm has become in recent years one of the most used and insightful techniques for the exploratory data analysis of high-dimensional data.

Approximated and User Steerable tSNE for Progressive Visual Analytics

no code implementations5 Dec 2015 Nicola Pezzotti, Boudewijn P. F. Lelieveldt, Laurens van der Maaten, Thomas Höllt, Elmar Eisemann, Anna Vilanova

Progressive Visual Analytics aims at improving the interactivity in existing analytics techniques by means of visualization as well as interaction with intermediate results.

Fuzzy Fibers: Uncertainty in dMRI Tractography

no code implementations11 Jul 2013 Thomas Schultz, Anna Vilanova, Ralph Brecheisen, Gordon Kindlmann

Fiber tracking based on diffusion weighted Magnetic Resonance Imaging (dMRI) allows for noninvasive reconstruction of fiber bundles in the human brain.
