Plotly-Resampler: Effective Visual Analytics for Large Time Series

1 code implementation17 Jun 2022 Jonas Van Der Donckt, Jeroen Van Der Donckt, Emiel Deprost, Sofie Van Hoecke

We observe that open source Python visualization toolkits empower data scientists in most visual analytics tasks, but lack the combination of scalability and interactivity to realize effective time series visualization.

Powershap: A Power-full Shapley Feature Selection Method

1 code implementation16 Jun 2022 Jarne Verhaeghe, Jeroen Van Der Donckt, Femke Ongenae, Sofie Van Hoecke

Benchmarks and simulations show that powershap outperforms other filter methods with predictive performances on par with wrapper methods while being significantly faster, often even reaching half or a third of the execution time.

R-GCN: The R Could Stand for Random

1 code implementation4 Mar 2022 Vic Degraeve, Gilles Vandewiele, Femke Ongenae, Sofie Van Hoecke

The inception of the Relational Graph Convolutional Network (R-GCN) marked a milestone in the Semantic Web domain as a widely cited method that generalises end-to-end hierarchical representation learning to Knowledge Graphs (KGs).

tsflex: flexible time series processing & feature extraction

1 code implementation24 Nov 2021 Jonas Van Der Donckt, Jeroen Van Der Donckt, Emiel Deprost, Sofie Van Hoecke

$\texttt{tsflex}$ is flexible as it supports (1) multivariate time series, (2) multiple window-stride configurations, and (3) integrates with processing and feature functions from other packages, while (4) making no assumptions about the data sampling regularity, series alignment, and data type.

Web Applicable Computer-aided Diagnosis of Glaucoma Using Deep Learning

no code implementations6 Dec 2018 Mijung Kim, Olivier Janssens, Ho-min Park, Jasper Zuallaert, Sofie Van Hoecke, Wesley De Neve

Glaucoma is a major eye disease, leading to vision loss in the absence of proper medical treatment.

GENESIM: genetic extraction of a single, interpretable model

1 code implementation17 Nov 2016 Gilles Vandewiele, Olivier Janssens, Femke Ongenae, Filip De Turck, Sofie Van Hoecke

The results show that GENESIM achieves a better predictive performance on most of these data sets than decision tree induction techniques and a predictive performance in the same order of magnitude as the ensemble techniques.
