چکیده

Abstract Data-driven methods based on machine learning have the potential to accelerate computational analysis of atomic structures. In this context, reliable uncertainty estimates are important for assessing confidence in predictions and enabling decision making. However, models can produce badly calibrated it is therefore crucial detect handle carefully. work we extend a message passing neural network designed specifically predicting properties molecules materials with probabilistic predictive distribution. The method presented paper differs from previous by considering both aleatoric epistemic unified framework, recalibrating distribution unseen data. Through computer experiments, show that our approach results accurate molecular formation energies well out training data two public benchmark datasets, QM9 PC9. proposed provides general framework evaluating ensemble able estimates.

Uncertainty of Artificial Neural Networks for Daily Evaporation Prediction (Case Study: Rasht and Manjil Stations)

This research uses the multilayer perceptron (MLP) model to predict daily evaporation at two synoptic stations located in Rasht and Manjil, Guilan province, in north-west of Iran. Initially the most important combinations of climatic parameters for both of the stations were identified using the gamma test; and daily evaporation were modeled based on the obtained optimal combination. The results...
