Scientific software from my research. Please refer to my Github pages for more details.

A machine-learning method for efficient free-energy estimation under periodic boundary conditions. It trains a diffusion-style score model on the Fokker-Planck dynamics, delivering accurate estimates in regimes where conventional approaches struggle.

dcTMD

#contributor12.2k17

An analysis framework for dissipation-corrected targeted molecular dynamics. It reconstructs free-energy profiles and friction factors along a pulled reaction coordinate from nonequilibrium pulling simulations.

MoSAIC

#creator38.9k29

A correlation-based feature selection method that groups collective coordinates by their mutual dependencies. It uncovers the essential degrees of freedom in high-dimensional data fully unsupervised, without prior assumptions.

NorMI

#creator14.4k23

A generalized Kraskov estimator for the normalized mutual information of multidimensional data. It quantifies nonlinear dependencies robustly, staying accurate even in high dimensions and with limited samples.
