ASPD links weight components to model activation features, using shared sparse representations and reconstruction objectives to ground components and reproduce matrix outputs. In GPT-2 small’s indirect object identification task, removing an identified query–key component pair substantially suppresses attention to the repeated-name position. This demonstrates an effect on that attention pattern, not that the model gives the wrong final answer.
