StegoGAN: Leveraging Steganography for Non-Bijective Image-to-Image Translation

no code implementations29 Mar 2024 Sidi Wu, Yizi Chen, Samuel Mermet, Lorenz Hurni, Konrad Schindler, Nicolas Gonthier, Loic Landrieu

Most image-to-image translation models postulate that a unique correspondence exists between the semantic classes of the source and target domains.

A Physics-driven GraphSAGE Method for Physical Process Simulations Described by Partial Differential Equations

no code implementations13 Mar 2024 Hang Hu, Sidi Wu, Guoxiong Cai, Na Liu

In this work, a physics-driven GraphSAGE approach (PD-GraphSAGE) based on the Galerkin method and piecewise polynomial nodal basis functions is presented to solve computational problems governed by irregular PDEs and to develop parametric PDE surrogate models.

Functional Autoencoder for Smoothing and Representation Learning

no code implementations17 Jan 2024 Sidi Wu, Cédric Beaulac, Jiguo Cao

A common pipeline in functional data analysis is to first convert the discretely observed data to smooth functions, and then represent the functions by a finite-dimensional vector of coefficients summarizing the information.

Cross-attention Spatio-temporal Context Transformer for Semantic Segmentation of Historical Maps

1 code implementation19 Oct 2023 Sidi Wu, Yizi Chen, Konrad Schindler, Lorenz Hurni

Even though our application is on segmenting historical maps, we believe that the method can be transferred into other fields with similar problems like temporal sequences of satellite images.

Neural Networks for Scalar Input and Functional Output

1 code implementation10 Aug 2022 Sidi Wu, Cédric Beaulac, Jiguo Cao

In this work, we propose a solution to this problem: a feed-forward neural network (NN) designed to predict a functional response using scalar inputs.

Neuroimaging Feature Extraction using a Neural Network Classifier for Imaging Genetics

no code implementations8 Jul 2022 Cédric Beaulac, Sidi Wu, Erin Gibson, Michelle F. Miranda, Jiguo Cao, Leno Rocha, Mirza Faisal Beg, Farouk S. Nathoo

A major issue in the association of genes to neuroimaging phenotypes is the high dimension of both genetic data and neuroimaging data.

FuncNN: An R Package to Fit Deep Neural Networks Using Generalized Input Spaces

no code implementations18 Sep 2020 Barinder Thind, Sidi Wu, Richard Groenewald, Jiguo Cao

Neural networks have excelled at regression and classification problems when the input space consists of scalar variables.
