Because\nShapley values are very computationally expensive, Vertex Explainable AI provides\napproximations instead of the exact values.\n\nYou can reduce the approximation error and get closer to the exact values by\nchanging the following inputs:\n\n- Increasing the number of integral steps or number of paths.\n\n### Increasing steps\n\nTo reduce approximation error, you can increase:\n\n- the **Number of integral steps** in the UI\n\nWhat's next\n-----------\n\n- Explore the [Limitations of Vertex Explainable AI](/vertex-ai/docs/explainable-ai/limitations)."]]
