Probabilistic topic models for sequence data

Webb13 apr. 2024 · In Data Assimilation (DA), the time dependent state of a system is estimated using two models that are the observational model, which relates the state to physical observations, and the dynamical model, that is used to propagate the state along the time dimension (Asch et al., 2016). These models can be written as a Hidden Markov Model … WebbUsing a compendium of single-cell ATAC-seq datasets from differentiating hematopoietic cells, brain and transcription factor perturbations, we demonstrate that topic modeling can be exploited for robust identification of cell types, enhancers and relevant transcription factors. cisTopic provides insight into the mechanisms underlying regulatory …
