Nevertheless, despite the promise afforded by deep learning and neural networks in computational chemistry, challenges remain. Universal ML models still struggle with nonuniform errors (depending on adsorbate and surface chemistry) as well as difficulty generalizing out of distribution . Improving the models will likely require even more training data as well as potential architectural changes to the models. Furthermore, model interpretation remains a challenge for state-of-the-art models. Despite limited interpretations now being possible[28],
