- dynamo.vf.MFPT(X_input, F, D=0.1, lambda_=1)[source]
Calculate the MFPT (mean first passage time) to convert from one cell state to another cell state by taking the optimal path.
The mean first-passage time (MFPT) defines an average timescale for a stochastic event to first occur. The MFPT maps a multi-step kinetic process to a coarse-grained timescale for reaching a final state, having started at some initial state. The inverse of the MFPT is an effective rate of the overall reaction. (reference: Mean First-Passage Times in Biology Nicholas F. Polizzi,a Michael J. Therien,b and David N. Beratan)
ndarray) – The initial guess of the least action path. Default is a straight line connecting the starting and end path.
Callable) – The reconstructed vector field function
float) – The diffusion constant. Note that this can be a space-dependent matrix.
lamada – Regularization parameter
- Return type:
The transition to convert from one cell state to another.
