Prédiction des adventices de la canne à sucre à La Réunion : une approche par apprentissage supervisé multi-labels Open
In agricultural surveys, weeds are considered as the most harmful pests. We propose a comparative study of multi-label classification algorithms to predict their weediness. The results show that the ML-ARAM and ML-kNN are the most efficien…

Predictive K-means with local models Open
Supervised classification can be effective for prediction but sometimes weak on interpretability or explainability (XAI). Clustering, on the other hand, tends to isolate categories or profiles that can be meaningful but there is no guarant…

Should we Reload Time Series Classification Performance Evaluation ? (a position paper) Open
Since the introduction and the public availability of the \textsc{ucr} time series benchmark data sets, numerous Time Series Classification (TSC) methods has been designed, evaluated and compared to each others. We suggest a critical view …

Supplementary material from "Mutualistic cleaner fish maintains high escape performance despite privileged relationship with predators" Open
Predatory reef fishes regularly visit mutualistic cleaner fish (Labroides dimidiatus) to get their ectoparasites removed but show no interest in eating them. The concept of compensated trait loss posits that characters can be lost i…

A Parameter-Free Approach for Mining Robust Sequential Classification Rules Open
Sequential data is generated in many domains of science and technology. Although many studies have been carried out for sequence classification in the past decade, the problem is still a challenge, particularly for pattern-based methods. W…

Cats & Co: Categorical Time Series Coclustering Open
We suggest a novel method of clustering and exploratory analysis of temporal event sequences data (also known as categorical time series) based on three-dimensional data grid models. A data set of temporal event sequences can be represente…
