func (m ConfusionMatrix) BandPrecision(b engine.Band) float64 · FN

Read the equation

This relation defines FN in the source section “func (m ConfusionMatrix) BandPrecision(b engine.Band) float64 · FN”. It specifies the displayed relationship between the named quantities or parameters. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

How it works

1. Read FN as the quantity being defined or updated by this relation.

2. Substitute the source-defined variables or recorded values and follow the displayed arithmetic and indexing exactly.

3. Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.

Assumptions & limits

• This source expression was recovered from the pinned code revision. Its presence does not establish that the associated program was built, run, or scientifically validated.

Original context

	if total == 0 {
		return 1.0
	}
	return float64(tp) / float64(total)
}

// BandRecall returns recall for the given band: TP / (TP + FN).
// FN = this band's cases that were scored into other bands.
func (m ConfusionMatrix) BandRecall(b engine.Band) float64 {
	tp := m[b][b]
	total := 0
	for scored := 0; scored < 3; scored++ {
		total += m[b][scored]
	}
	if total == 0 {
		return 1.0
	}
	return float64(tp) / float64(total)

FN = this band's cases that were scored into other bands.
