Lao License Plate Provinces

Cropped Lao license-plate images labelled with the issuing province (18 classes), plus the plate letters, digits, and color.

• —Task: image classification (province from a plate crop).
• —Splits are grouped by plate (province+letters+digits) so the same physical plate never appears in two splits — honest eval. Seed 42, ~80/10/10.
• —label is a ClassLabel over the 18 canonical provinces; province is the Lao string.
• —reviewed: yes = consensus-verified (two independent reads agreed), pred = auto-accepted (Vientiane Capital + a few high-reliability provinces).
• —Old ກຳແພງນະຄອນ plates are canonicalised to ນະຄອນຫຼວງວຽງຈັນ.

Per-class counts (train+val+test)

Note: the set is skewed toward ນະຄອນຫຼວງວຽງຈັນ (Vientiane Capital). Ten provinces still have <100 samples (some are capped by how rarely they appear in the source footage). Train with class-weighted loss / a weighted sampler, and keep growing the thin classes via active learning.
