Fully Hyperbolic Convolutional Neural Networks for Computer Vision

1 code implementation28 Mar 2023 Ahmad Bdeir, Kristian Schwethelm, Niels Landwehr

To address this, we present HCNN, a fully hyperbolic convolutional neural network (CNN) designed for computer vision tasks.

Deep Distributional Sequence Embeddings Based on a Wasserstein Loss

no code implementations4 Dec 2019 Ahmed Abdelwahab, Niels Landwehr

In this paper, we study deep distributional embeddings of sequences, where the embedding of a sequence is given by the distribution of learned deep features across the sequence.

A Discriminative Model for Identifying Readers and Assessing Text Comprehension from Eye Movements

no code implementations21 Sep 2018 Silvia Makowski, Lena Jäger, Ahmed Abdelwahab, Niels Landwehr, Tobias Scheffer

We study whether a Fisher-SVM with this Fisher kernel and several reference methods are able to identify readers and estimate their level of text comprehension based on eye-tracking data.

Reading Comprehension

A Semiparametric Model for Bayesian Reader Identification

no code implementations EMNLP 2016 Ahmed Abdelwahab, Reinhold Kliegl, Niels Landwehr

We study the problem of identifying individuals based on their characteristic gaze patterns during reading of arbitrary text.

Varying-coefficient models with isotropic Gaussian process priors

no code implementations28 Aug 2015 Matthias Bussas, Christoph Sawade, Tobias Scheffer, Niels Landwehr

We study learning problems in which the conditional distribution of the output given the input varies as a function of additional task variables.

Bayesian Inference

Active Comparison of Prediction Models

no code implementations NeurIPS 2012 Christoph Sawade, Niels Landwehr, Tobias Scheffer

We address the problem of comparing the risks of two given predictive models - for instance, a baseline model and a challenger - as confidently as possible on a fixed labeling budget.

Model Selection

Active Estimation of F-Measures

no code implementations NeurIPS 2010 Christoph Sawade, Niels Landwehr, Tobias Scheffer

We address the problem of estimating the F-measure of a given model as accurately as possible on a fixed labeling budget.
