perplexity {celda} | R Documentation |
Perplexity can be seen as a measure of how well a provided set of cluster assignments fit the data being clustered.
perplexity(counts, celdaMod, newCounts = NULL)
counts |
Integer matrix. Rows represent features and columns represent cells. This matrix should be the same as the one used to generate 'celdaMod'. |
celdaMod |
celdaModel. Options available in 'celda::availableModels'. |
newCounts |
A newCounts matrix used to calculate perplexity. If NULL, perplexity will be calculated for the 'counts' matrix. Default NULL. |
Numeric. The perplexity for the provided count data and model.
data(celdaCGSim, celdaCGMod) perplexity <- perplexity(celdaCGSim$counts, celdaCGMod)
