Clustering of miR mature expression: consensus NMF
Overview
Introduction

This pipeline calculates clusters based on a consensus non-negative matrix factorization (NMF) clustering method [1],[2]. This pipeline has the following features:

  1. Convert input data set to a non-negitive matrix by column rank normalization.

  2. Classify samples into consensus clusters.

  3. Determine differentially expressed marker miRs for each subtype.

Summary

The most robust consensus NMF clustering of 80 samples using the 278 most variable miRs was identified for k = 5 clusters. We computed the clustering for k = 2 to k = 10 and used the cophenetic correlation coefficient and the average silhouette width calculation to determine the robust clusters.

Results
miR expression patterns of molecular subtypes

Figure 1.  Get High-res Image Samples were separated into 5 clusters. Shown are 80 samples and 550 marker miRs. The color bar of the row indicates the marker miRs for the corresponding cluster.

Figure 2.  Get High-res Image Heatmap with a standard hierarchical clustering for 80 samples and the 278 most variable miRs. *The NA values were changed to 0 for this figure.

Silhouette widths, Cophenetic Correlation Coefficients and Consensus matrix

Figure 3.  Get High-res Image The silhouette width was calculated for each sample and each value of k. The left upper panel shows the average silhouette width across all samples for each tested k (left upper panel). The left lower panel shows the Cophenetic Correlation Coefficients for each tested k. The right panel shows assignments of clusters to samples and the silhouette width of each sample for the most robust clustering.

Figure 4.  Get High-res Image The consensus matrix after clustering shows 5 clusters with limited overlap between clusters.

Marker miRs of each subtype

Samples most representative of the clusters, hereby called core samples were identified based on positive silhouette width, indicating higher similarity to their own class than to any other class member. Core samples were used to select differentially expressed marker miRs for each subtype by comparing the subclass versus the other subclasses, using Student's t-test.

Methods & Data
Input

miR (MIMATs) of RPM value (reads per million reads aligned to miRBase mature) with log2 transformed was as the input data for the clustering.

  • Input file = TCGA-UVM-TP.expclu.gct

CNMF Method

Non-negative matrix factorization (NMF) is an unsupervised learning algorithm that has been shown to identify molecular patterns when applied to miR expression data [1],[2]. Rather than separating miR clusters based on distance computation, NMF detects contextdependent patterns of miR expression in complex biological systems.

Cophenetic Correlation Coefficient and How to select the best cluster

We use the cophenetic correlation coefficients to determine the cluster that yields the most robust clustering. The cophenetic correlation coefficient is computed as the Pearson correlation of two distance matric: one is the distance between samples induced by the consensus matrix, and the other is the distance between samples induced by the linkage used in the reordingering of consensus matrix. The cophenetic correlation coefficient lies between 0 and 1. We select the best cluster k where the magnitude of the cophenetic correlation coefficient begins to fall[1]. If there are more than one peak points, we will select one with higer silhouette width. If there is no peak point, we will select the k with max cophenetic correlation coefficient.

Silhouette Width

Silhouette width is defined as the ratio of average distance of each sample to samples in the same cluster to the smallest distance to samples not in the same cluster. If silhouette width is close to 1, it means that sample is well clustered. If silhouette width is close to -1, it means that sample is misclassified [3][4].
