Dataset | ||
======= | ||
|
||
something here. | ||
Xenon.Py embed with ``elements`` and ``elements_completed`` dataset for descriptors calculation. | ||
These data are summarized from `mendeleev`_, `pymatgen`_, `CRC Hand Book`_ and `Magpie`_. | ||
|
||
``elements`` dataset contains 118 elements with 74 elemental features(incomplete). | ||
``elements_completed`` is imputed version by use multiple imputation chained equation [1]_. | ||
|
||
Because a large number of missing data in high atomic number elements lead to difficulty impute. | ||
The ``elements_completed`` dataset only have 94 elements from `H` to `Pu` with 58 features. | ||
