La metodología adoptada fue de tipo aplicado, con un diseño experimental de enfoque descriptivo y transversal. Los resultados de la aplicación de estos modelos revelaron diferenciassignificativas en términos de eficiencia predictiva. El RLM y la RRNA destacaron con coeficientes de determinación (R²) de 0.922 y 0.939, respectivamente, indicando una capacidad sustancial para explicar la variabilidad en el consumo de potencia. En contraste, los modelos basados en árboles (RAD y RBA) mostraron desempeño inferior, con R² de 0.762 y 0. 471. Al analizarmétricas clave como el Error Absoluto Medio (MAE), el Error Cuadrático Medio (MSE) y la Raíz del Error Cuadrático Medio (RMSE), se confirmó que tanto el RLM como la RRNA superaron alos modelos basados en árboles. Estos resultados respaldan la elección de RLM y RRNA como modelos preferidos para la estimación del consumo de potencia en un molino Semi-autógeno.  \nPalabras clave: Machine Learning, molino Semi-autógeno, potencia (kW) .  \nAbstract  \nThis research aimed to develop machine learning (ML) models to estimate power consumption (Kw) in a Semi-autogenous mill in the mining industry. Using Machine Learning algorithms considering various operating variables for the different models such as Multiple Linear Regression (RLM), Decision Tree Regression (RAD), Random Forest Regression (RBA) and Regression Artificial Neural Networks (ANN) . The methodology adopted was applied, with an experimental design with a descriptive and transversal approach. The results of the application of these models revealed significant differences in terms of predictive efficiency. The RLM and RRNA stood out with coefficients of determination (R²) of 0.922 and 0.939, respectively, indicating a substantial capacity to explain the variability in power consumption. In contrast, the tree-based models (RAD and RBA) showed inferior performance, with R² of 0.762 and 0.471. When analyzing key metrics such as Mean Absolute Error (MAE), Mean Square Error (MSE) and Root Root Mean Square Error (RMSE), it was confirmed that both RLM and RRNA outperformed the tree-based models. These results support the choice of RLM and RRNA as preferred models for estimating  \npower consumption in a Semi-autogenous mill.  \nKeywords: Machine Learning, Semi-autogenous mill, power (kW) .  \nPlease cite this article as: Vera M. , Vega J. , Bailon F. , Multivariable predictive models for the estimation of power consumption (kW) of a Semi-autogenous mill applying Machine Learning algorithms , Journal of Ene","cbCaifcGDM3FaWvg","https://ap.wps.com/l/cbCaifcGDM3FaWvg","pdf",806570,6,1,18,"English","en",105,"# Introduction\n## Energy consumption and sensor-driven data in mining\n## Importance of grinding and SAG mills\n## Rationale for ML-based power estimation\n# Materials and Methods\n## Data and operational variables\n## Machine learning models applied\n## Experimental design and evaluation metrics\n# Results and Discussion\n## Predictive performance across models\n## Determination coefficients (R²)\n## Error metrics: MAE, MSE, RMSE\n# Conclusions\n## Preferred models for SAG power estimation","[{\"question\":\"What is the main objective of the study?\",\"answer\":\"To develop machine learning models that estimate power consumption (kW) for a semi-autogenous mill in the mining industry.\"},{\"question\":\"Which machine learning algorithms are compared?\",\"answer\":\"The study compares Multiple Linear Regression, Decision Tree Regression, Random Forest Regression, and Artificial Neural Networks, using operational variables as inputs.\"},{\"question\":\"How do the models perform in terms of accuracy?\",\"answer\":\"RLM and ANN show stronger predictive efficiency, with higher R² values than tree-based models, and they also outperform them on MAE, MSE, and RMSE.\"}]","Multivariable predictive models for the estimation of power consumption (kW) of a Semi-autogenous mill applying Machine Learning algorithms -
