چکیده
In this study, accurate and convenient prediction models of tubular solar still performance, expressed as hourly production, were developed by utilizing machine learning. Based on experimental data, the compared, such classical artificial neural network with/without Baysian optimization, random forest traditional multilinear regression. Before applying Bayesian both predict production. But superiority is well behaved with insignificant error. The performance forest, regression calculated 0.9758, 0.9614, 0.9267 for determination coefficients, 5.21%, 7.697%, 10.911% mean absolute percentage error, respectively. Additionally, when optimization searching most appropriate hyper parameters, was significantly improved 35%. Moreover, findings revealed that less sensitive to parameters than network. robustness high accuracy, recommended in predicting production still.

Practical Bayesian Optimization of Machine Learning Algorithms
The use of machine learning algorithms frequently involves careful tuning of learning parameters and model hyperparameters. Unfortunately, this tuning is often a “black art” requiring expert experience, rules of thumb, or sometimes bruteforce search. There is therefore great appeal for automatic approaches that can optimize the performance of any given learning algorithm to the problem at hand....
