brunodoamaral / _dice.py

Last active March 16, 2024 18:00 — forked from JDWarner/_dice.py

Dice coefficient between two boolean NumPy arrays or array-like data. This is commonly used as a set similarity measurement (though note it is not a true metric; it does not satisfy the triangle inequality). The dimensionality of the input is completely arbitrary, but `im1.shape` and `im2.shape` much be equal. This Gist is licensed under the mod…

	def dice(im1, im2, empty_score=1.0):
	"""
	Computes the Dice coefficient, a measure of set similarity.
	Parameters
	----------
	im1 : array-like, bool
	Any array of arbitrary size. If not boolean, will be converted.
	im2 : array-like, bool
	Any other array of identical size. If not boolean, will be converted.
	Returns
