Universal Machine Learning Model

Definition

In machine learning, a universal model refers to a model that can be used broadly within a single domain.

Explanation

The definition of a universal model may be easier to grasp by comparing it with the bespoke model. For instance, suppose our goal is to develop a neural network that approximates the energy of matter. Here, a model trained only on data from specific environments such as exsolved nanoparticles, ternary metal oxides, quantum dots, and amorphous silicon is called a bespoke model. In contrast, SevenNet-Omni can be called a universal model because it was trained on a broad dataset spanning inorganic crystals, catalysts, MOFs (metal-organic frameworks), molecules, and more.

Difference from Foundation Models

The universal model and the 🔒(26/07/06)foundation model are often used interchangeably, but their emphases differ. Whereas the universal model focuses on handling a variety of problems within a single domain, such as atomic systems, the scope of the foundation model does not remain confined to a single field. Above all, it emphasizes being trained at large scale on vast data that spans modalities and fields.

A representative example is the latest versions of models such as ChatGPT, Gemini, and Claude. These models can handle whatever the user wants, regardless of the field (mathematics, physics, the humanities, etc.) or the form of the data (images, audio, text, etc.).
