• Abstract summary: In this paper, an in-depth analysis of Escherichia coli seawater measurements during the bathing season in Rijeka, Croatia was conducted. Submerged sources of groundwater were observed at several measurement locations which could be the cause for increased E. coli values. A cascade machine learning model is used to predict coastal water quality based on meteorological data.

• Abstract: In this paper, an in-depth analysis of Escherichia coli seawater measurements during the bathing season in the city of Rijeka, Croatia was conducted. Submerged sources of groundwater were observed at several measurement locations which could be the cause for increased E. coli values. This specificity of karst terrain is usually not considered during the monitoring process, thus a novel measurement methodology is proposed. A cascade machine learning model is used to predict coastal water quality based on meteorological data, which improves the level of accuracy due to data imbalance resulting from rare occurrences of measurements with reduced water quality. Currently, the cascade model is employed as a filter method, where measurements not classified as excellent quality need to be further analyzed. However, with improvements proposed in the paper, the cascade model could be ultimately used as a standalone method.

• Generative Modelling of Stochastic Rotating Shallow Water Noise [44.99833362998488]
  This paper develops a generic methodology for calibrating the noise in fluid dynamics partial equations where the differentiality was introduced to parametrize subgrid-scale processes. The parameterization of sub-grid scale processes is required in the estimation of uncertainty in weather and climate predictions, to represent systematic model errors arising from subgrid-scale fluctuations. The methodology is tested on a rotating shallow water model with the elevation variable of the model used as input data. The numerical simulations show that the noise is indeed non-Gaussian.

  A novel machine learning method is formulated for modeling groundwater levels by learning from a 3D lithological texture model of the Central Valley aquifer. We show how the model predictions may be used to supplement hydrological understanding of aquifer responses in basins with irregular well data. Our results indicate that on average the 2017 and 2019 wet years in California were largely ineffective in replenishing the groundwater loss caused during previous drought years.

  Tobit model is a well-known linear regression model for analyzing censored data. In this study, we devised a novel extension of the classical Tobit model, called the emphmulti-target Tobit model, to handle multiple censored variables simultaneously. Experiments conducted using several real-world water quality datasets provided evidence that estimating multiple columns jointly gains a great advantage over estimating them separately.

• Revisiting the Calibration of Modern Neural Networks [44.26439222399464]
  Many instances of miscalibration in modern neural networks have been reported, suggesting a trend that newer, more accurate models produce poorly calibrated predictions. We systematically relate model calibration and accuracy, and find that the most recent models, notably those not using convolutions, are among the best calibrated. We also show that model size and amount of pretraining do not fully explain these differences, suggesting that architecture is a major determinant of calibration properties.

  Inferring the parameters of a model based on experimental observations is central to the scientific method. A particularly challenging setting is when the model is strongly indeterminate, i.e., when distinct sets of parameters yield identical observations. We present a method for cracking such indeterminacy by exploiting additional information conveyed by an auxiliary set of observations sharing global parameters.
