This Python package offers tools for building the model terms as decompositions of various basis functions. It is possible to model the terms e.g. as Gaussian processes (with reduced dimensionality) of various kernels, as piecewise linear functions, and as B-splines, among others. Of course, ...

Inferring cellular trajectories using a variety of omic data is a critical task in single-cell data science. However, accurate prediction of cell fates, and thereby biologically meaningful discovery, is challenged by the sheer size of single-cell data, t
For this purpose, we apply a special ansatz solution together with the Fourier transform (for the space variable) and the Laplace transform (with respect to time) on the FSE and obtain the Gaussian hypergeometric differential equation. By applying the inverse Fourier transform on the solution of ...
We implemented the GSNAc Model using Python. We selected the platform of GSNAc to be compatible with python’s sklearn library33since it is the de facto standard platform in the ML domain. Also, it allows parameter optimization by grid or random search methods, making it useful to find the...
4.5.2. The simulations were produced by a Python code that is openly available at https://github.com/panchoop/DGCG_algorithm/. For all the simulations, we employ the following: the considered domain is \(\Omega := (0,1)\times (0,1) \subset \mathbb {R}^2\), the number of time...
