New WARP framework infers foundation model training data from weights

Researchers have developed a new framework called WARP that can infer the training data mixtures used for foundation models directly from their released weights. This method bypasses the need for direct access to the training data or trajectory, which is typically kept private by model developers. WARP works by analyzing the geometric footprint of the training data in the weight space, allowing it to approximate domain proportions with high accuracy, outperforming existing methods like membership inference.
