RNA-based sample discrimination and classification can be used to provide biological insights and/or distinguish between clinical groups. However, finding informative differences between sample groups can be challenging due to the multidimensional and noisy nature of sequencing data. Here, we apply a machine learning approach for hierarchical discrimination and classification of samples with high-dimensional miRNA expression data. Our protocol comprises data preprocessing, unsupervised learning, feature selection, and machine-learning-based hierarchical classification, alongside open-source MATLAB code.
基于RNA的样本鉴别和分类可用于提供生物学见解和/或区分临床组。然而，由于测序数据具有多维度和噪声的特性，在样本组之间找到信息性差异可能具有挑战性。在这里，我们应用一种机器学习方法，对具有高维miRNA表达数据的样本进行分层鉴别和分类。我们的方案包括数据预处理、无监督学习、特征选择和基于机器学习的分层分类，以及开源的MATLAB代码。
