On the Transmission of Texts: Written Cultures as Complex Systems

Our knowledge of past cultures relies considerably on written material. For centuries, texts have been copied, altered, then transmitted or lost - eventually, from surviving documents, philologists attempt to reconstruct text phylogenies ("stemmata"…

About ∆-numeration

In this article we study a numeration system previously used to prove combinatorial properties in discrete geometry: the ∆-numeration. Since this system, introduced via the fully subtractive algorithm, has been seen mainly as a tool, we propose here…

Unsupervised learning from attributed networks

Unlike the plain network where only the topological structure is available, nodes of attributed networks possess rich attributed information. Thereby, the attributed networks ubiquitous in the real world have attracted much attention in recent years…

S-EO: A Large-Scale Dataset for Geometry-Aware Shadow Detection in Remote Sensing Applications

We introduce the S-EO dataset: a large-scale, highresolution dataset, designed to advance geometry-aware shadow detection. Collected from diverse public-domain sources, including challenge datasets and government providers such as USGS, our dataset…

Gaussian Splatting for Efficient Satellite Image Photogrammetry

Recently, Gaussian splatting has emerged as a strong alternative to NeRF, demonstrating impressive 3D modeling capabilities while requiring only a fraction of the training and rendering time. In this paper, we show how the standard Gaussian…

Joint dimensionality reduction and clustering with missing data

To address the challenge of clustering highdimensional data, subspace clustering methods, such as Reduced K-means (RKM) have been proposed. These methods identify clusters by simultaneously finding the low-dimensional subspaces and the matching…

Étude de variabilité par bootstrap résiduel pour une méthode de subspace clustering

Combining dimensionality reduction and clustering techniques is effective for clustering high-dimensional data by simultaneously identifying low-dimensional subspaces and their corresponding partitions. This work aims to assess the sensitivity of…

Clustering et réduction de la dimension avec données manquantes

In the context of high-dimensional clustering, we are interested in the Reduced K-means (RKM) subspace clustering method. However, RKM is not suitable for missing data. We propose two methods inspired by commonly used approaches for clustering with…

Disaggregation of Heating and Cooling Energy Consumption via Maximum a Posteriori Estimation

Estimating energy use in heating and air conditioning systems is crucial for effective building energy management. This article introduces a new method combining the use of degree-days with the maximum a posteriori estimation statistical method to…
