dynamo.vf.IntGrad

dynamo.vf.IntGrad(points, Function, DiffusionMatrix, dt)[source]

Calculate the action of the path based on the (reconstructed) vector field function and diffusion matrix (Eq. 18)

Parameters
  • points ('np.ndarray') – The sampled points in the state space used to calculate the action.

  • Function ('function') – The (learned) vector field function.

  • DiffusionMatrix ('function') – The function that returns diffusion matrix which can be dependent on the variables (for example, genes)

  • dt ('function') – The time interval used in calculating action

Returns

integral – The action calculated based on the input path, the vector field function and the diffusion matrix.

Return type

‘np.ndarray’
