New Method Transfers Black-Box AI Knowledge to Different Feature Sets

Researchers have developed a novel method for transferring knowledge from pre-trained black-box predictive functions to new, heterogeneous input spaces. This approach decomposes the target regression function into a transferable component, informed by the black box, and a non-transferable component specific to the new space. The method utilizes a two-step neural network procedure, leveraging abundant unlabeled data to estimate the transferable component and limited labeled data for the non-transferable part. This technique offers improved prediction risk bounds compared to non-transfer methods, especially when the non-transferable component is small or smooth, and can be extended to aggregate knowledge from multiple black boxes.
