TL;DR: We propose a new machine learning framework named Big Learning, which exhaustively exploits data information and underlies existing foundation models.

Abstract: Recent breakthroughs based on big/foundation models reveal a vague avenue for AI, that is, \emph{big data, big/foundation models, big learning, $\cdots$}. Following that avenue, here we elaborate on our newly introduced big learning. Specifically, big learning exhaustively exploits the information/tasks inherent in its large-scale \emph{complete/incomplete} training data, by learning to simultaneously model many/all joint/conditional/marginal data distributions (thus named big learning) with one universal foundation model. We reveal that big learning is what existing foundation models are implicitly doing; accordingly, our big learning provides high-level guidance for flexible design and improvements of foundation models. Besides, big learning ($i$) is equipped with great flexibilities for complete/incomplete training data and for customizing trustworthy data tasks; ($ii$) potentially delivers all joint/conditional/marginal data capabilities after training; ($iii$) significantly reduces the training-test gap with improved model generalization; and ($iv$) potentially unifies conventional machine learning paradigms and enables their flexible cooperations, manifested as a universal learning paradigm. Preliminary experiments verified the effectiveness of the presented big learning.
