pysiglib.branched_sig_length#

branched_sig_length(dimension, degree, *, planar=False, scalar_term=False)[source]#

Returns the length of a truncated branched signature.

Parameters:

  • dimension – Dimension of the underlying path.

  • degree – Maximum tree order (number of nodes).

  • planar – If True, return the length for planar (ordered) branched signatures.

  • scalar_term – If True, includes the empty-tree scalar term at index 0 in the length. If False (default), the returned length is one less (matching branched_sig output with scalar_term=False).

Returns:

Length of the branched signature array.
