Weblibrary (fastTopics) ``` Simulate a "toy" gene expression data set from the multinomial topic model. Each sample---here, a vector of 400 counts---is generated as a mixture of three gene programs (the topics in the topic model). In particular, samples are mostly generated by either a single gene WebNov 19, 2024 · fastTopics The package implements algorithms for data count of fitting topic models and non-negative matrix factorization. The methods exploit the relationship between the probabilistic latent semantic index and Poisson … WebWhen FastReport creates the report and encounters an expression enclosed in square brackets the report engine calculates the expression's value and inserts this value into … hemorigen na hemoroidy
