Constructing Time-Varying Gene Regulatory Networks
Discovered gene regulation networks are very helpful to understand biological mechanisms and predict unknown gene functions.Little literature has been done toward estimating time-varying networks from time series data.In this paper,we develop a new method to discover the dynamic,and delay interactions between genes based on gene expression data.The method builds on time lagged mutual information and a temporally smoothed l1-regularized logistic regression.To evaluate our method,we use both simulated and biological data from the yeast cell cycle in regulatory networks modeling.Results demonstrate the superior performance of our method.
