Optimizing existing technologies in this field has become inevitable with the increasing demand for renewable energy sources. Among the renewable resources that have attracted much attention in research, biomass resources can be mentioned. In this study, an attempt has been made to examine one of the technologies for extracting energy from biomass resources - gasification - and to optimize and control this technology as much as possible, after forming a database extracted from a comprehensive review of related articles, its outputs have been predicted using several techniques in the field of artificial intelligence and machine learning. The statistical artificial intelligence methods used in this study were selected after reviewing similar articles. They included linear regression, gradient boosting regression, decision tree regression, random forest regression, support vector regression, and kernel ridge regression. Finally, this research resulted in several AI-based forecasting models with different forecast accuracies, which were evaluated with the relevant statistical parameters. Among the aforementioned machine learning techniques and considering the various parameters for evaluating the accuracy of the models, the most important of which is the squared error in the test data, the linear regression, gradient boosting regression, and random forest regression methods, whose squared error rates in each of the models were 0.909, 0.829, and 0.818, respectively, showed better performance than other proposed technologies.

EXTENDED ABSTRACT
With the increasing demand for renewable energy sources, the optimization of existing technologies in this field has become inevitable. Among different renewable energy sources, biomass showed great potential possessing features such as being abundant, environmental-friendly (e.g. lower environmental impact, being carbon-neutral, etc.), low-cost, and producing a wide variety of desirable products. The mentioned advantageous characteristics resulted in its importance in the current global energy supply and accountability for above 70 percent of green energy production.
In this research, an attempt has been made to examine one of the technologies for extracting energy from biomass sources - gasification - and in order to optimize and control this technology as much as possible, after gathering data and making the database, its outputs by using several techniques in the field of artificial intelligence and learning Machines are predicted. The statistical artificial intelligence methods used in this research were selected after reviewing similar articles and include linear regression (LR), gradient boosting regression (GBR), decision tree regression (DTR), random forest regression (RFR), Support vector regression (SVR) and kernel Ridge Regression (KRR).
Machine learning (ML) shows great potential for being a fast, relatively inexpensive, and accurate approach to predicting gasification outputs. Although some efforts have been made to predict the effect of control parameters on the gasification output, this paper offers a comprehensive approach to evaluate the relationship between different biomass precursor characteristics and the energy output of the gasification process with the aid of different data-driven ML techniques. Finally, this research resulted in several prediction models based on artificial intelligence with different prediction accuracies. Among the mentioned machine learning techniques and taking into account various parameters for assessing the accuracy of models, among the most important of which we can mention the square error in the test data, linear regression (LR), gradient boosting regression (GBR) and Random Forest Regression (RFR) with r-squared of 0.909, 0/829 and 0/818 performed better than the rest of the proposed technologies.
