Ensemble-Based Data Assimilation MethodsEnsemble-based methods have become very popular for data assimilation in numerical models of oceanic or atmospheric flows. Unlike the deterministic Extended Kalman Filter which explicitly describes thPierre Brasseur...
the design of ensemble methods. This work shows that it provides a theoretical and practical tool to develop new ensemble methods well-tuned to the characteristics of a specific base learner. On the basis of the analysis and experiments performed on SVMs and bagged ensembles of ...
Don’t Take the Easy Way Out:Ensemble Based Methods for Avoiding Known Dataset Biases Abstract 最先进的模型通常利用数据中的表面模式,这些模式不能很好地泛化到域外或对抗性设置中。 例如,文本蕴涵模型经常学习特定关键词意味着蕴涵,而不管上下文,而视觉问答模型学习预测原型答案,而不考虑图像中的信息。 在本文...

A novel localization scheme for scalar uncertainties in ensemble-based data assimilation methodsHistory matchingES-MDADistance-dependent localizationNon-distance-dependent localizationCorrelation-based adaptive localizationHistory matching, also known as data assimilation, is an inverse problem with multiple ...
Ensemble-based anomaly detection methods still face some challenges, however, such as data imbalance, time and space demand and the selection of base detectors. To this end, we propose a selective ensemble method for anomaly detection based on parallel learning (SEAD-PL). First, a differentiated...
To overcome this shortcoming, this paper proposes the robust localization method based on ensemble-based manifold learning in wireless sensor networks, and analyzes two ensemble-based methods. Experimental results show that this method not only improves the location accuracy, but also decreases the ...
Ensemble methods for graph-based keyword spotting (KWS) allow us to combine the graph edit distances (GEDs) of different graph representations of the same manuscript (i.e. George Washington (GW), P...

Although new ensemble-based methods to account for uncertainty in short term quantitative precipitation forecasts (QPF's) are being developed, methods to account for uncertainty in existing short term deterministic QPF's are needed for immediate application in AHPS. Existing ensemble streamflow prediction...
