“…Latent block clustering methods have been proposed using a Poisson model, for example in information retrieval (Li & Zha, 2006), or for sequencing data (Witten, 2011), among others. With the aim of reducing the number of parameters and at the same time to facilitate the interpretation, clustering and representation methods have been proposed in different areas for different data sets (see, e.g., Kim, Choi, & Hwang, 2017;Vera, Mac ıas, & Heiser, 2009a, Vera, Mac ıas, & Heiser, 2009bVera, Mac ıas, & Heiser, 2013).…”
