Ocean Wave Directional Distribution from GPS Buoy Observations off the West Coast of Ireland: Assessment of a Wavelet-Based Method

Knowledge of the directional distribution of a wave field is crucial for a better understanding of complex air-sea interactions. However, the dynamic and unpredictable nature of ocean waves, combined with the limitations of existing measurement…

Topological data analysis for unsupervised anomaly detection in time series

In this article, we propose a new algorithm for unsupervised anomaly detection in univariate time series, based on topological data analysis. It relies on delay embeddings and on the extraction of persistent cycles from the 1-dimensional persistent…

Accelerating NeRF with the Visual Hull

Neural rendering methods for learning the appearance and geometry of 3D scenes have gained tremendous popularity since 2020. In this field, NeRF or Neural Radiance Fields is the bestknown methodology. Given a collection of multi-view images and…

Survival Forest for Left-Truncated Right-Censored Data

The estimation of the lifetime of an industrial equipment or a patient is often based on censored data, because the event of interest is observed only for a subsample of observations. The use of the Random Forest algorithm applied to industrial data…

Dehazing with Dark Channel Prior: Analysis and Implementation

In outdoor scenes, atmospheric absortion and scattering attenuate the radiance received by the camera and may produce haze. In 2009 He et al. proposed a simple but effective dehazing algorithm based on a hypothesis called the 'dark channel prior' …
