Comparación de Cinco Modelos de Machine Learning para la Predicción de las Elecciones Presidenciales en Colombia: una Perspectiva con Datos Composicionales

In recent years, numerous studies have employed machine learning techniques and compositional data analysis in various fields of study. However, their integration into electoral analysis remains limited. For this reason, this work combines both approaches by applying five machine learning models: random forest, gradient boosting, support vector machines, k-nearest neighbors, and feedforward neural networks, to predict the results of the presidential elections in Colombia at the municipal level, onsidering the data as compositional. Specifically, it forecasts the vote distribution in each municipality along a unidimensional Left-Right ideological spectrum. This approach aims not only to improve prediction accuracy but also to comtribute a significant advancement in methodologies applied to electoral analysis. The models were trained on 70% of the presidential election data from 2002 to 2022 and evaluated on the remaining 30%. The algorithms demonstrated similar performance across transformations of each ideological spectrum, with variability percentages between 56% and 94% in predicting vote proportions, with the feedforward neural networks model using the centered log-ratio transformation achieving the best results.

The Telecommunications sector has been characterized by being a dynamic, highly competitive sector, this implies that as productivity increases, the probability of occupational accidents also increase, especially due to work at heights; This degree work aims to evaluate compliance with the minimum standards of the Occupational Health and Safety Management System (SG-SST) in the company GRUPO EMPRESARIAL MIDEAS COLOMBIA S.A.S, in accordance with Resolution 0312 of 2019. For this, the methodology included carrying out the initial self-assessment through the minimum standards tool of the ARL SURA, which the company is affiliated with, identifying a CRITICAL state of compliance, which evidenced the need for immediate intervention; The designed the documentation required for the implementation of the SG-SST, ensuring its compliance with current regulations and socialization with management was key to guaranteeing its commitment to the application of the PDCA cycle (Plan, Do, Check, Act). As a result, it was confirmed that the company had not developed any phase of the PDCA cycle, demonstrating a lack of planning, implementation, monitoring, and continuous improvement in occupational health and safety at all levels. Likewise, an improvement plan and recommendations were established, structured based on the findings of the initial assessment. Sharing the results with management enabled the generation of managerial and organizational commitment, key to the continued effective implementation of the OSHMS. In conclusion, the assessment revealed significant noncompliance with minimum standards, and documents were developed to facilitate their implementation. The acceptance and commitment of senior management will be crucial to ensuring continuous improvement and compliance with regulations, thus contributing to the safety and well-being of its workers.

Safety and health at work require comprehensive training of all personnel, from direct employees to contractors, to guarantee compliance with regulations and safe and healthy work environments. This training should address topics such as hazard identification, risk assessment and the controls necessary to mitigate them; This is why, according to Resolution 0312 of 2019, it is necessary to implement various activities and programs to improve occupational health and safety management. These include: training on occupational health issues, formation of brigades, periodic medical evaluations, inspections, and the strengthening of coexistence and COPASST committees, among other activities aimed at guaranteeing the activities of collaborators focused on a culture of safety and health. labor. Through the self-assessment of the Occupational Health and Safety Management System, it revealed the need to improve training, induction and re-induction plans, form emergency brigades and evaluate the health conditions of workers. To address these deficiencies, an action plan was implemented based on the PHVA cycle, allowing not only to comply with regulatory requirements, but also to take actions including documenting and implementing the standards that were non-compliant in favor of risk prevention and improvement. of workers' well-being

Physical activity does not need to be strenuous to be beneficial. For an average adult with a sedentary lifestyle, 30 minutes of moderate-intensity physical activity, every day or most days, will be sufficient to obtain health benefits. health benefits. What's more, those 30 minutes can be accumulated over the course of the day in small bouts of activity or exercise. You don't need to play vigorous sports, belong to an expensive gym or purchase special equipment to achieve positive health results. equipment to achieve positive health results. This is why the need was born to create a space to advise people to start or maintain good lifestyle habits not only for vanity but also for health. The World Health Organization defines physical activity as “all movements that are part of daily life, including work, recreation, exercise and sports activities”. In reality, physical activity is a broad term that encompasses activities ranging in intensity from regular stair climbing, dancing and walking to running, cycling and sports. Moderate physical activity can be carried out by anyone, and can be anyone, as well as fit into the daily routine. Physical activity can be incorporated in different ways throughout the day.
