Abstract

Nowadays a huge volume of biomedical data (images, genes, etc) are daily generated. The interpretation of such data involves a considerable expertise. The misinterpretation and/or misdetection of a suspicious clinical finding leads to increasing the negligence claims, and redundant procedures (e.g. biopsies). The analysis of biomedical data is a complex task which are performed by specialists on whose expertise degree affects the accuracy of their diagnosis. Besides, due to the huge volume of data, it is a tiresome process. To mitigate these intrinsic drawbacks Computeraided Diagnosis approaches have been proposed in the last decade, but applied without a deep analysis. It is also very common in the literature for the presentation of experimental results to rely solely on the mean of accuracy values. This procedure is not always reliable, especially for applications that require faster classifiers due to their learning-time constraints. Hence, in this paper we proposed an extensive analysis towards an effective and efficient learning for biomedical data classification. To do so, several public biomedical datasets were used against different supervised classifiers, taking into account accuracies and computational times obtained throughout the learning process.
面向生物医学数据分类的有效学习
如今,每天都会产生大量的生物医学数据(图像、基因等)。对这类数据的解释需要相当多的专业知识。对可疑临床发现的错误解释和/或错误检测导致疏忽索赔的增加和多余的程序(例如活组织检查)。生物医学数据分析是一项复杂的任务,由专家完成,其专业程度影响其诊断的准确性。此外,由于数据量巨大,这是一个令人厌烦的过程。为了减轻这些内在的缺陷,计算机辅助诊断方法在过去十年中被提出,但没有深入的分析。在文献中,仅依靠精度值的平均值来表示实验结果也是很常见的。这个过程并不总是可靠的,特别是对于由于学习时间限制而需要更快分类器的应用程序。因此,在本文中,我们提出了对生物医学数据分类的有效和高效学习的广泛分析。为此,考虑到整个学习过程中获得的准确性和计算时间,将几个公共生物医学数据集用于不同的监督分类器。
