Expressing:

Article Title: Service reliability evaluation of highway tunnel based on digital image processing.
Article Snippet: In Matlab, the contour coefficient is calculated by using the silhouette function [32].

Article Title: Heterogeneity Assessment and Protein Pathway Prediction via Spatial Lipidomic and Proteomic Correlation: Advancing Dry Proteomics concept for Human Glioblastoma Prognosis.
Article Snippet: Silhouette plot was calculated using the function silhouette in Matlab.

Article Title: Protocol for hybrid flux balance, statistical, and machine learning analysis of multi-omic data from the cyanobacterium Synechococcus sp. PCC 7002
Article Snippet: The initial pre-plot in displays silhouette values ( y ) against the number of clusters selected ( x ), which indicates the best value to select for K (i.e., the number of clusters with the highest silhouette value): prompt = 'k − means: Press ''y'' if the number of cluster is known, or any other key to execute silhouette analysis '; answer = input(prompt,'s'); % if strcmp(answer,'y') mean_silhouette = zeros(1,30); for NoClust = 2:30 [cidx, ctrs] = kmeans(genes_vs_profiles,NoClust,'dist','correlation','rep',5, 'disp','final'); Note: Upon selecting a value for K , the silhouette function in MATLAB produces a plot ( ) that displays values for each individual cluster within the range of [−1,1].

Article Title: SoundScape learning: An automatic method for separating fish chorus in marine soundscapes.
Article Snippet: The Silhouette score (SS) was calculated using the mean intracluster (i) and near-cluster distance (n) for each sample; the Silhouette score for a sample is defined by SS 1⁄4 n i max i; nð Þ : (6) Silhouette scores were calculated for original and low rank matrices using the silhouette function in MATLAB to create plots that visualize differences in cluster quality.

Article Title: Two stages of speech envelope tracking in human auditory cortex modulated by speech intelligibility.
Article Snippet: To evaluate the explanatory power of the cluster results, we calculated the percent variance (R2) with the following function: R2 = 1 − ∑( X − X̂ )2 ∑( Xi − X̂ )2 To evaluate the clustering goodness of fit, the silhouette index (SI) was calculated to evaluate cluster separability using the silhouette function in Matlab R2018b.

Article Title: Neural response properties predict perceived contents and locations elicited by intracranial electrical stimulation of human auditory cortex.
Article Snippet: To evaluate the explanatory power of the cluster results, we calculated the percent variance (R2) with the following function: R2 = 1 − ∑ ( X − X̂ )2 ∑ ( Xi − X )2 (2) We calculated the silhouette index (SI) to evaluate the clustering goodness of fit using the silhouette function in Matlab.

Example l/vlPAG vgat traces (bottom). b Order of assays. c L/vlPAG vgat activity centered at eating onset (cricket assay n = 223 neurons; walnut assay n = 204 neurons). d Representation of behaviors in principal component space (PC) during cricket hunting (see example on left). Clustering quality was measured by silhouette score, which was higher than the chance level of zero (dotted red line) ( n = 4 mice; one-sample two-tailed t -test, t-statistic = 2.79, p = 0.059). e Same as d , but for walnut ( n = 4 mice; one-one-sample two-tailed t -test, t-statistic = 14.37, p = 0.001). f Behaviors were decoded above chance (red dotted line) ( n = 4 mice; one-sample two-tailed t -test, cricket t-statistics: approach = 3.87, p = 0.031; eat = 5.59, p = 0.011; walnut t-statistics: approach = 4.75, p = 0.018, eat = 7.53, p = 0.005). g Cells co-registered across assays. h Mahalanobis distance between points from two clusters that display higher overlap (left panel with light and dark blue points) and two clusters that are well-separated (right panel with light and dark green points). i Mahalanobis distance between approach and eating clusters across the cricket and walnut assays in n-dimensions ( n = # of co-registered neurons). The distance between eating clusters across assays is smaller than the distance between approach clusters, indicating the representation of eating is more conserved than food approach (approach sample n = 527 time points, eat sample n = 1958 time points; two-tailed Wilcoxon rank-sum test, z-score = 22.88, p < 0.001). j Same as d , but for co-registered cells, showing conserved representation of behaviors across assays ( n = 4 mice; one-one-sample two-tailed t -test, t-statistic = 4.22, p = 0.024). k The distance between individual points and cluster center is smaller in the eating cluster than the approach cluster, indicating the representation of eating is more conserved across assays (approach sample n = 1049 time points, eat sample n = 5492 time points; two-tailed Wilcoxon rank-sum two-tailed test, z-score = 10.35, p < 0.001). *** p < 0.001, ** p < 0.01, * p < 0.05, † p = 0.059.
