报告摘要:

Complex disease progression, such as cancer, is generally a nonlinear process with three stages, i.e., normal state, pre-disease state, and disease state, where the pre-disease state is the critical state just before disease appearance. It is generally a challenging task to identify the pre-disease state. In this talk, by exploiting the information of differential associations among the observed molecules between the normal and pre-disease states, we introduce a computational approach, i.e., single-sample landscape entropy (SLE) method, to identify the tipping point during disease progression with only one sample data. Specifically, by evaluating the disorder of a network projected from a single-sample data, SLE effectively characterizes the criticality of this single sample network in terms of network entropy, thereby capturing not only the signals of the impending transition but also its leading network, i.e. dynamic network biomarkers.
