XPSTablesModelColumnInfo

import type { XPSTablesModelColumnInfo } from "https://googleapis.deno.dev/v1/language:v2.ts";

An information specific to given column and Tables Model, in context of the Model and the predictions created by it.

interface XPSTablesModelColumnInfo {
columnId?: number;
featureImportance?: number;
}

§Properties

§
columnId?: number
[src]

The ID of the column.

§
featureImportance?: number
[src]

When given as part of a Model: Measurement of how much model predictions correctness on the TEST data depend on values in this column. A value between 0 and 1, higher means higher influence. These values are normalized

  • for all input feature columns of a given model they add to 1. When given back by Predict or Batch Predict: Measurement of how impactful for the prediction returned for the given row the value in this column was. Specifically, the feature importance specifies the marginal contribution that the feature made to the prediction score compared to the baseline score. These values are computed using the Sampled Shapley method.
