ML of excited states
==========================================

There are several ways to learn and predict excited-state energies and forces with MLatom. You can train a single model for each state or use our MS-ANI to learn all electronic state energies and forces simultaneously. It is recommended that you get familiar with :ref:`excited-state data format <tutorial_es_data>` in MLatom which are required for training ML models. See the manuals for other cases such as application of ML for :ref:`UV/vis one- <cl_manual_UV>` and :ref:`two-photon <cl_manual_two_photon_absorption>` absorption calculations.
