摘要:

这项工作汇集了一些最常见的机器学习(ML)算法,目标是在从一组不平衡数据中获得的结果的水平上进行比较。该数据集由近17000个对天文物体进行的观测组成,以识别天体(HTRU2)。该方法建议的基础上评估这些不同的模型在同一数据库中的准确性处理不平衡数据的两种不同的策略。结果表明,尽管这种类型的数据中存在噪声和不平衡的类,它是可能的,将它们应用于标准的ML算法,并获得有前途的准确率。

英文摘要:

This work brings together some of the most common machine learning (ML) algorithms, and the objective is to make a comparison at the level of obtained results from a set of unbalanced data. This dataset is composed of almost 17 thousand observations made to astronomical objects to identify pulsars (HTRU2). The methodological proposal based on evaluating the accuracy of these different models on the same database treated with two different strategies for unbalanced data. The results show that in spite of the noise and unbalance of classes present in this type of data, it is possible to apply them on standard ML algorithms and obtain promising accuracy ratios.
