Matrix prior for data transfer between single cell data types in latent Dirichlet allocation
Fig 4
Quantitative improvement of perplexity values with the matrix prior.
Perplexity values (y-axis) demonstrate quantitative improvement of the LDA model after using the matrix prior (darker colors) compared to the uniform prior (lighter colors) for various values of the weight of the prior (x-axis). The same procedure was used for both the SHARE-seq data set (blue) and the C. elegans data set (red). Each point is a separate split of the target data into a test and a training set.
