MobileFaceNet

Lightweight real‑time face verification on‑device.

MobileFaceNet is an efficient CNN that maps a 112x112 face image to a compact 128‑dimensional embedding. Two embeddings are compared via cosine similarity to determine whether they belong to the same person, achieving 99.48% accuracy on the LFW benchmark. The model uses depthwise‑separable convolutions and inverted residual blocks (MobileNetV2‑style) to stay under 1M parameters, making it well‑suited for real‑time face verification on mobile and edge devices. Trained with ArcFace loss on MS‑Celeb‑1M.
