UnverifiedThe new probe architecture can aggregate information across multiple layers and multiple token positions, whereas traditional linear probes are usually trained only on a single layer or the last token.53% similarUnverifiedPractical precision positioning systems often adopt a hybrid "coarse positioning + fine positioning" scheme: the screw handles long-travel movement, and the piezoelectric stage handles final fine adjustment.52% similar
