Visualisation Methods for Diachronic Semantic Shift

no code implementations sdp (COLING) 2022 Raef Kazi, Alessandra Amato, ShengHui Wang, Doina Bucur

We develop three visualisation methods that can show, given a root word: the temporal change in its linguistic context, word re-occurrence, degree of similarity, time continuity, and separate trends per publisher location.

Understanding Sparse Neural Networks from their Topology via Multipartite Graph Representations

1 code implementation26 May 2023 Elia Cunegatti, Matteo Farina, Doina Bucur, Giovanni Iacca

With these novelties, we show the following: (a) The proposed MGE allows to extract topological metrics that are much better predictors of the accuracy drop than metrics computed from current input-agnostic BGEs; (b) Which metrics are important at different sparsity levels and for different architectures; (c) A mixture of our topological metrics can rank PaI algorithms more effectively than Ramanujan-based metrics.

Large-scale multi-objective influence maximisation with network downscaling

1 code implementation13 Apr 2022 Elia Cunegatti, Giovanni Iacca, Doina Bucur

Finding the most influential nodes in a network is a computationally hard problem with several possible applications in various kinds of network-based problems.

Automated fault tree learning from continuous-valued sensor data: a case study on domestic heaters

no code implementations13 Mar 2022 Bart Verkuil, Carlos E. Budde, Doina Bucur

We obtain fault trees for the 11 failure variables, and evaluate them in two ways: quantitatively, with a significance score, and qualitatively, with domain specialists.

Bias in Automated Image Colorization: Metrics and Error Types

1 code implementation16 Feb 2022 Frank Stapel, Floris Weers, Doina Bucur

We measure the color shifts present in colorized images from the ADE20K dataset, when colorized by the automatic GAN-based DeOldify model.

The network signature of constellation line figures

1 code implementation19 Oct 2021 Doina Bucur

We then form the network of constellations (as linked by their similarity), to study how similar cultures are by computing their assortativity (or homophily) over the network.

Independent Prototype Propagation for Zero-Shot Compositionality

1 code implementation NeurIPS 2021 Frank Ruis, Gertjan Burghouts, Doina Bucur

Next we propagate the independent prototypes through a compositional graph, to learn compositional prototypes of novel attribute-object combinations that reflect the dependencies of the target distribution.

Attribute Compositional Zero-Shot Learning

Top influencers can be identified universally by combining classical centralities

no code implementations13 Jun 2020 Doina Bucur

Information flow, opinion, and epidemics spread over structured networks.

Causal Discovery with Attention-Based Convolutional Neural Networks

1 code implementation Machine Learning and Knowledge Extraction 2019 Meike Nauta, Doina Bucur, Christin Seifert

We therefore present the Temporal Causal Discovery Framework (TCDF), a deep learning framework that learns a causal graph structure by discovering causal relationships in observational time series data.
