Feature Space
The feature space chart is an interactive graph of the feature space of predictors. Here a subspace is shown, with the features Horsepower [horsepow], Engine size [engine_s], and Price in thousands [price] represented on the axes.
- Shape indicates the partition to which a point belongs, with the two holdouts (the prototypes) represented by triangles.
- The holdouts are also focal cases, and are outlined in red. Lines connect the focal cases to their k nearest neighbors.
By clicking and dragging the chart, you can rotate it to get a better view of the distribution of points in the feature space.
