Probabilistic Calibration by Design for Neural Network Regression

2 code implementations18 Mar 2024 Victor Dheur, Souhaib Ben Taieb

To address the miscalibration issue of neural networks, various methods have been proposed to improve calibration, including post-hoc methods that adjust predictions after training and regularization methods that act during training.

Distribution-Free Conformal Joint Prediction Regions for Neural Marked Temporal Point Processes

1 code implementation9 Jan 2024 Victor Dheur, Tanguy Bosser, Rafael Izbicki, Souhaib Ben Taieb

A primary objective is to generate a distribution-free joint prediction region for the arrival time and mark, with a finite-sample marginal coverage guarantee.

Anomaly detection with semi-supervised classification based on risk estimators

no code implementations1 Sep 2023 Le Thi Khanh Hien, Sukanya Patra, Souhaib Ben Taieb

A significant limitation of one-class classification anomaly detection methods is their reliance on the assumption that unlabeled training data only contains normal instances.

On the Predictive Accuracy of Neural Temporal Point Process Models for Continuous-time Event Data

1 code implementation29 Jun 2023 Tanguy Bosser, Souhaib Ben Taieb

To bridge this gap, we present a comprehensive large-scale experimental study that systematically evaluates the predictive accuracy of state-of-the-art neural TPP models.

Coherent probabilistic forecasts for hierarchical time series

no code implementations ICML 2017 Souhaib Ben Taieb, James W. Taylor, Rob J. Hyndman

Many applications require forecasts for a hierarchy comprising a set of time series along with aggregates of subsets of these series.

A review and comparison of strategies for multi-step ahead time series forecasting based on the NN5 forecasting competition

no code implementations16 Aug 2011 Souhaib Ben Taieb, Gianluca Bontempi, Amir Atiya, Antti Sorjamaa

To attain such an objective, we performed a large scale comparison of these different strategies using a large experimental benchmark (namely the 111 series from the NN5 forecasting competition).
