Texto completoWind power experiences a tremendous development of its installed capacities in Europe. Though, the intermittence of wind generation causes difficulties in the management of power systems. Also, in the context of the deregulation of electricity markets, wind energy is penalized by its intermittent nature. It is recognized today that the forecasting of wind power for horizons up to 2/3-day ahead eases the integration of wind generation. Wind power forecasts are traditionally provided in the form of point predictions, which correspond to the most-likely power production for a given horizon. That sole information is not sufficient for developing optimal management or trading strategies. Therefore, we investigate on possible ways for estimating the uncertainty of wind power forecasts. The characteristics of the prediction uncertainty are described by a thorough study of the performance of some of the state-of-the-art approaches, and by underlining the influence of some variables e. G. Level of predicted power on distributions of prediction errors. Then, a generic method for the estimation of prediction intervals is introduced. This statistical method is non-parametric and utilizes fuzzy logic concepts for integrating expertise on the prediction uncertainty characteristics. By estimating several prediction intervals at once, one obtains predictive distributions of wind power output. The proposed method is evaluated in terms of its reliability, sharpness and resolution. In parallel, we explore the potential use of ensemble predictions for skill forecasting. Wind power ensemble forecasts are obtained either by converting meteorological ensembles (from ECMWF and NCEP) to power or by applying a poor man’s temporal approach. A proposal for the definition of prediction risk indices is given, reflecting the disagreement between ensemble members over a set of successive look-ahead times. Such prediction risk indices may comprise a more comprehensive signal on the expected level of uncertainty in an operational environment. A probabilistic relation between classes of risk indices and the level of forecast error is shown. In a final part, the trading application is considered for demonstrating the value of uncertainty estimation when predicting wind generation. It is explained how to integrate that uncertainty information in a decision-making process accounting for the sensitivity of end-users to regulation costs. The benefits of having a probabilistic view of wind power forecasting are clearly shown

Texto completoThis thesis explores the intersection of machine learning (ML) and safety, aiming to address challenges associated with the deployment of intelligent systems in real-world scenarios. Despite significant progress in ML, concerns related to privacy, fairness, and trustworthiness have emerged, prompting the need for enhancing the reliability of AI systems. The central focus of the thesis is to enable ML algorithms to detect deviations from normal behavior, thereby contributing to the overall safety of intelligent systems.The thesis begins by establishing the foundational concepts of out-of-distribution (OOD) detection and misclassification detection in Chapter 1, providing essential background literature and explaining key principles. The introduction emphasizes the importance of addressing issues related to unintended and harmful behavior in ML, particularly when AI systems produce unexpected outcomes due to various factors such as mismatches in data distributions.In Chapter 2, the thesis introduces a novel OOD detection method based on the Fisher-Rao geodesic distance between probability distributions. This approach unifies the formulation of detection scores for both network logits and feature spaces, contributing to improved robustness and reliability in identifying samples outside the training distribution.Chapter 3 presents an unsupervised OOD detection method that analyzes neural trajectories without requiring supervision or hyperparameter tuning. This method aims to identify atypical sample trajectories through various layers, enhancing the adaptability of ML models to diverse scenarios.Chapter 4 focuses on consolidating and enhancing OOD detection by combining multiple detectors effectively. It presents a universal method for ensembling existing detectors, transforming the problem into a multi-variate hypothesis test and leveraging meta-analysis tools. This approach improves data shift detection, making it a valuable tool for real-time model performance monitoring in dynamic and evolving environments.In Chapter 5, the thesis addresses misclassification detection and uncertainty estimation through a data-driven approach, introducing a practical closed-form solution. The method quantifies uncertainty relative to an observer, distinguishing between confident and uncertain predictions even in the face of challenging or unfamiliar data. This contributes to a more nuanced understanding of the model's confidence and helps flag predictions requiring human intervention.The thesis concludes by discussing future perspectives and directions for improving safety in ML and AI, emphasizing the ongoing evolution of AI systems towards greater transparency, robustness, and trustworthiness. The collective work presented in the thesis represents a significant step forward in advancing AI safety, contributing to the development of more reliable and trustworthy machine learning models that can operate effectively in diverse and dynamic real-world scenarios
