In MADAS, a fingerprint is the combination of a _descriptor_, i.e., an encoding of material properties, and a _similarity measure_, i.e., a function that takes two descriptors as arguments and returns their similarity in a range between 0 and 1, where 0 means that both fingerprints are completely dissimilar, and 1 means that they are identical. MADAS allows to compute different built-in fingerprints, as well as supports the creation of custom fingerprints." ] }, { "cell_type": "markdown", "id": "46fa445a-732d-4818-bb65-b513b401b7bf", "metadata": {}, "source": [ "In this tutorial you are going to learn how to:\n", "\n", "
