Smoothed targets depend on classes observed in the batch · case 05

Smoothed targets depend on classes observed in the batch.

Member previewVariant 5 · 3 implementations · 7 checks per implementation

Case contract

For each valid class index y, emit length-C target with confidence at y and equal remaining mass across other C-1 classes. For C=1 emit [1]; invalid y emits zeros.

Why this case matters

A small deterministic training-data operation makes label ownership and ordering explicit.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
declared classes beyond batch	`[[0.8]]`	`[[0.8, 0.033333333333, 0.033333333333, 0.033333333333, 0.033333333333, 0.033333333333, 0.033333333333]]`	Failed
