defmodule Microwaveprop.Pskr.FeatureBin do
|
|
@moduledoc """
|
|
One feature-bucket row from a `Pskr.RecalibrationRun`. Stores the
|
|
spot-density statistics for a (band, feature, bin) cell of the
|
|
corpus so an operator can read whether a feature actually
|
|
discriminates propagation at the granularity the scorer cares
|
|
about.
|
|
|
|
Example: at run R, on the 10 GHz band, the `pwat_mm` feature has
|
|
five rows (one per bin label: `<15`, `15-25`, `25-40`, `40-55`,
|
|
`>55`). Each row carries:
|
|
* `sample_count` — how many corpus samples landed in the bin
|
|
* `spot_count_total` — sum of spot_count across those samples
|
|
* `spot_count_avg` / `spot_count_p50` / `spot_count_p90` —
|
|
central tendency + tail for the spot-density distribution
|
|
|
|
The unique key (run_id, band, feature, bin_label) means a rerun
|
|
of the same recalibration run is idempotent.
