# Model comparison via simplicial complexes and persistent homology

@article{Vittadello2021ModelCV, title={Model comparison via simplicial complexes and persistent homology}, author={Sean T. Vittadello and Michael P. H. Stumpf}, journal={Royal Society Open Science}, year={2021}, volume={8} }

In many scientific and technological contexts, we have only a poor understanding of the structure and details of appropriate mathematical models. We often, therefore, need to compare different models. With available data we can use formal statistical model selection to compare and contrast the ability of different mathematical models to describe such data. There is, however, a lack of rigorous methods to compare different models a priori. Here, we develop and illustrate two such approaches that… Expand

Multi-model and network inference based on ensemble estimates: avoiding the madness of crowds

- Computer Science, Medicine

In the cases of model selection and network inference when the authors can trust ensembles, and when they should be cautious, the analyses suggest that the careful construction of an ensemble—choosing good predictors—is of paramount importance. Expand

A Comprehensive Network Atlas Reveals That Turing Patterns Are Common but Not Robust.

It is found that network structure alone neither implies nor guarantees emergent TPs, which implies that TP networks are more common than previously thought, and evolution might regularly encounter prototypic solutions. Expand
