Calculate_feature_matrix only uses functions from Pandas/Numpy/Scipy for increasing performance over raw Python and numba or cython helps specifically in PandasBackend class and in individual feature computation functions.It’s complexity is more for installation because it requires a compiled C code or a C compiler.
Due to this complexity it is low in our priority list. So, we are focused on scaling our small datasets towards larger datasets which demands parallelization rather than subroutine optimization.
