Prior Data Fitted Network

Prior-data fitted networks (PFNs) represent a novel approach to machine learning that leverages pre-trained transformer models to perform in-context learning, enabling fast and accurate predictions on new tasks without retraining. Current research focuses on enhancing PFNs for specific data types, such as tabular data (TabPFN) and time series (LaT-PFN), and improving their scalability and interpretability. This paradigm shift offers significant potential for accelerating various machine learning applications, particularly in scenarios with limited data or a need for rapid inference, by bypassing traditional model selection and hyperparameter tuning.
