A stochastic network approach to clustering and visualising single-cell genomic count data
Thomas E. Bartlett, Swati Chandna, Sandipan Roy
Important tasks in the study of genomic data include the identification of groups of similar cells (for example by clustering), and visualisation of data summaries (for example by…
Two-way sparsity for time-varying networks, with applications in genomics
Thomas E. Bartlett, Ioannis Kosmidis, Ricardo Silva
We propose a novel way of modelling time-varying networks, by inducing two-way sparsity on local models of node connectivity. This two-way sparsity separately promotes sparsity acr…
Co-modularity and Detection of Co-communities
Thomas E. Bartlett
This paper introduces the notion of co-modularity, to co-cluster observations of bipartite networks into co-communities. The task of co-clustering is to group together nodes of one…
A Power Variance Test for Nonstationarity in Complex-Valued Signals
Thomas E. Bartlett, Adam M. Sykulski, Sofia C. Olhede +2
We propose a novel algorithm for testing the hypothesis of nonstationarity in complex-valued signals. The implementation uses both the bootstrap and the Fast Fourier Transform such…
