An AI model built on thermodynamics to learn from diverse datasets

What is it about?

This publication introduces ZENN, a new AI framework built on thermodynamic principles to improve learning from diverse datasets. Current AI methods often assume data is uniform, but real-world data, such as images, text, and scientific measurements, comes from multiple sources and conditions. This variability makes accurate predictions difficult. ZENN addresses this challenge by embedding thermodynamic concepts like energy and entropy into neural networks, enabling the model to capture hidden heterogeneity and uncertainty in data. We demonstrate ZENN’s effectiveness in image and text classification tasks, where it outperforms state-of-the-art methods, and in scientific applications such as reconstructing energy landscapes and predicting critical points in Invar like Fe3Pt. By combining physics and machine learning, ZENN offers a robust, interpretable approach for handling complex, multisource data.

Why is it important?

Modern AI increasingly relies on heterogeneous data for applications such as digital twins, climate modeling, and materials discovery. Existing methods often fail to account for internal disparities, limiting accuracy and scalability. ZENN is unique because it builds AI on the foundation of thermodynamic laws, bridging two traditionally separate domains. This approach not only improves performance in machine learning tasks but also enables breakthroughs in scientific modeling, such as predicting phase transitions and negative thermal expansion. By making AI physically grounded and data-efficient, ZENN opens new possibilities for accelerating innovation across science and technology.
