Structured factorization for single-cell gene expression data
Antonio Canale, Luisa Galtarossa, Davide Risso +2
Single-cell gene expression data are often characterized by large matrices, where the number of cells may be lower than the number of genes of interest. Factorization models have e…
Accelerated structured matrix factorization
Lorenzo Schiavon, Bernardo Nipoti, Antonio Canale
Matrix factorization exploits the idea that, in complex high-dimensional data, the actual signal typically lies in lower-dimensional structures. These lower dimensional objects pro…
Generalized infinite factorization models
Lorenzo Schiavon, Antonio Canale, David B. Dunson
Factorization models express a statistical object of interest in terms of a collection of simpler objects. For example, a matrix or tensor can be expressed as a sum of rank-one com…
On the dependence in football match outcomes: traditional model assumptions and an alternative proposal
Marco Petretta, Lorenzo Schiavon, Jacopo Diquigiovanni
The approaches routinely used to model the outcomes of football matches are characterised by strong assumptions about the dependence between the number of goals scored by the two c…
