Reliable Evapotranspiration Predictions with a Probabilistic Machine Learning Framework
نویسندگان
چکیده
Evapotranspiration is often expressed in terms of reference crop evapotranspiration (ETo), actual (ETa), or surface water evaporation (Esw), and their reliable predictions are critical for groundwater, irrigation, aquatic ecosystem management semi-arid regions. We demonstrated that a newly developed probabilistic machine learning (ML) model, using hybridized “boosting” framework, can simultaneously predict the daily ETo, Esw, & ETa from local hydroclimate data with high accuracy. The approach exhibited great potential to overcome uncertainties, which 100% 89.9% 93% test at three watersheds were within models’ 95% prediction intervals. modeling results revealed hybrid boosting framework be used as computational tool ETo while bypassing net solar radiation calculations, estimate Esw overcoming uncertainties associated pan coefficients, offsetting capital operational costs EC towers. In addition, Shapley analysis built on coalition game theory, we identified order importance interactions between hydroclimatic variables enhance transparency trustworthiness.

Reliable Classifications with Machine Learning
In the past decades Machine Learning algorithms have been successfully used in several classification problems. While they often significantly outperform domain experts (in terms of classification accuracy or otherwise), they are mostly not being used in practice. A plausible reason for this is that it is difficult to obtain an unbiased estimation of a single classification’s reliability. While...
متن کاملEstimating Evapotranspiration using Machine Learning Techniques
The measurement of evapotranspiration is the most important factor in irrigation scheduling. Evapotranspiration means loss of water from the surface of plant and soil. Evaporation parameters are being used in studying water balances, water resource management, and irrigation system design and for estimating plant growth and height as well. Evapotranspiration is measured by different methods by ...

متن کاملHedging predictions in machine learning
Recent advances in machine learning make it possible to design efficient prediction algorithms for data sets with huge numbers of parameters. This article describes a new technique for ‘hedging’ the predictions output by many such algorithms, including support vector machines, kernel ridge regression, kernel nearest neighbours, and by many other state-of-the-art methods. The hedged predictions ...
