Polaratio: A magnitude-contingent monotonic correlation metric and its improvements to scRNA-seq clustering
Victor Wang, Pietro Antonio Cicalese, Anto Sam Crosslee Louis Sam Titus, Chandra Mohan
Motivation: Single-cell RNA sequencing (scRNA-seq) technologies and analysis tools have allowed researchers to achieve remarkably detailed understandings of the roles and relationships between cells and genes. However, conventional distance metrics, such as Euclidean, Pearson, and Spearman distances, fail to simultaneously take into account the high dimensionality, monotonicity, and magnitude of gene expression data. To address several shortcomings in these commonly used metrics, we present a magnitude-contingent monotonic correlation metric called Polaratio which is designed to enhance the quality of scRNA-seq data analysis. Results: We integrate three state-of-the-art interpretable clustering algorithms – Single-Cell Consensus Clustering (SC3), Hierarchical Clustering (HC), and K-Medoids (KM) – through a consensus cell clustering procedure, which we evaluate on various biological datasets to benchmark Polaratio against several well-known metrics. Our results demonstrate Polaratio’s ability to improve the accuracy of cell clustering on 5 out of 7 publicly available datasets.
