Researchers have introduced MAxBench, a new evaluation framework designed to assess multinomial concept representations in language models. This framework is geometry-agnostic and samples from recovered concept representations to compare different localization methods. The study found that affine subspaces are more reliable for steering and have better recall than rank-one or linear subspaces, with non-zero offsets contributing significantly to this advantage. Manifold steering also proved competitive, though no method consistently outperformed prompting. AI
