Reasoning about Ambiguous Definite Descriptions

1 code implementation23 Oct 2023 Stefan F. Schouten, Peter Bloem, Ilia Markov, Piek Vossen

But no resources exist to evaluate how well Large Language Models can use explicit reasoning to resolve ambiguity in language.

GRAPES: Learning to Sample Graphs for Scalable Graph Neural Networks

1 code implementation5 Oct 2023 Taraneh Younesian, Thiviyan Thanapalasingam, Emile van Krieken, Daniel Daza, Peter Bloem

Graph neural networks (GNNs) learn the representation of nodes in a graph by aggregating the neighborhood information in various ways.

Uncertainty Intervals for Graph-based Spatio-Temporal Traffic Prediction

no code implementations9 Dec 2020 Tijs Maas, Peter Bloem

Many traffic prediction applications rely on uncertainty estimates instead of the mean prediction.

A Hybrid 3DCNN and 3DC-LSTM based model for 4D Spatio-temporal fMRI data: An ABIDE Autism Classification study

no code implementations14 Feb 2020 Ahmed El-Gazzar, Mirjam Quaak, Leonardo Cerliani, Peter Bloem, Guido van Wingen, Rajat Mani Thomas

Functional Magnetic Resonance Imaging (fMRI) captures the temporal dynamics of neural activity as a function of spatial location in the brain.

Exploiting Temporality for Semi-Supervised Video Segmentation

1 code implementation29 Aug 2019 Radu Sibechi, Olaf Booij, Nora Baka, Peter Bloem

In this paper, we tackle the issue of label scarcity by using consecutive frames of a video, where only one frame is annotated.

Image Segmentation Segmentation +3

End-to-End Learning from Complex Multigraphs with Latent-Graph Convolutional Networks

1 code implementation14 Aug 2019 Floris Hermsen, Peter Bloem, Fabian Jansen, Wolf Vos

We study the problem of end-to-end learning from complex multigraphs with potentially very large numbers of edges between two vertices, each edge labeled with rich information.

Three Tools for Practical Differential Privacy

no code implementations7 Dec 2018 Koen Lennart van der Veen, Ruben Seggers, Peter Bloem, Giorgio Patrini

Differentially private learning on real-world data poses challenges for standard machine learning practice: privacy guarantees are difficult to interpret, hyperparameter tuning on private data reduces the privacy budget, and ad-hoc privacy attacks are often required to test model privacy.

A tutorial on MDL hypothesis testing for graph analysis

no code implementations31 Oct 2018 Peter Bloem, Steven de Rooij

This document provides a tutorial description of the use of the MDL principle in complex graph analysis.

Two-sample testing

Learning sparse transformations through backpropagation

2 code implementations22 Oct 2018 Peter Bloem

Many transformations in deep learning architectures are sparsely connected.

Deep Learning for Classification Tasks on Geospatial Vector Polygons

1 code implementation11 Jun 2018 Rein van 't Veer, Peter Bloem, Erwin Folmer

In this paper, we evaluate the accuracy of deep learning approaches on geospatial vector geometry classification tasks.

An Expectation-Maximization Algorithm for the Fractal Inverse Problem

1 code implementation9 Jun 2017 Peter Bloem, Steven de Rooij

We present an Expectation-Maximization algorithm for the fractal inverse problem: the problem of fitting a fractal model to data.

Large-scale network motif analysis using compression

no code implementations8 Jan 2017 Peter Bloem, Steven de Rooij

We introduce a new method for finding network motifs: interesting or informative subgraph patterns in a network.
