Svm-Do: Identification Of Tumor-Discriminating Mrna Signatures Via Support Vectormachines Supported By Disease Ontology, Mustafa Erhan Özer, Pemra Özbek Sarica, Kazim Yalçin Arğa
Turkish Journal of Biology
Background/aim: The complicated nature of tumor formation makes it difficult to identify discriminatory genes. Recently, transcriptome-based supervised classification methods using support vector machines (SVMs) have become popular in this field. However, the inclusion of less significant variables in the construction of classification models can lead to misclassification. To improve model performance, feature selection methods such as enrichment analysis can be used to extract useful variable sets. The detection of genes that can discriminate between normal and tumor samples in the association of cancer and disease remains an area of limited information. We therefore aimed to discover novel and practical sets …
