Downsample
Thins a dataset's own points by count, fraction or stride, depending on the kind of dataset.
Inputs
| Port | Accepts | Required | Description |
|---|---|---|---|
x | dataset | required | The dataset to downsample |
Parameter ports
Added from the Parameters pane (⊕). While connected, each drives its parameter.
| Port | Accepts | Mode | Description |
|---|---|---|---|
count | primitive(number) | opt-in drives count | Drives the Count parameter while connected |
fraction | primitive(number) | opt-in drives fraction | Drives the Fraction parameter while connected |
seed | primitive(number) | opt-in drives seed | Drives the Seed parameter while connected |
stride | primitive(number) | opt-in drives stride | Drives the Stride parameter while connected |
stride_r | primitive(number) | opt-in drives stride_r | Drives the Stride R parameter while connected |
stride_t | primitive(number) | opt-in drives stride_t | Drives the Stride T parameter while connected |
stride_p | primitive(number) | opt-in drives stride_p | Drives the Stride P parameter while connected |
Outputs
