## ざっくり言うと
- 分類先が日々増えるような顔認識では,通常の分類モデルを作り続けるのは難しい.そこで距離空間を学習し,KNNのような方法で判別する方法が取られる.
- クラス内分散が小さく,クラス間分散が大きいと,判別しやすい
- 顔認識等で用いられる距離学習において,ArcFaceという学習モデル(ロス関数)を提案
- ArcFaceは通常のsoftmaxへ渡される部分を内積では…

Hi, actually, follow your instruction, after 28000 iterations, the loss decrease to 4.x. So, my question is one model can be used correct, what loss should be decreased to? Or, I should reset the max …

Hi
it seems the matlab script to produce the video demo is missing. Can anyone guide me to it?
I would appreciate it.

## 概要
大規模顔認識で使える特徴量学習において、超球面上の幾何学的な距離とマージンを考えることで、分類問題として学習するだけでより discriminative な特徴量を学習できるという手法を提案した。
具体的には、通常の sof…

Hi@tpys , you align the face image into 112x96, however,I need to align it into 112x112(insight face, which is similar with sphereface), so I simply changed the ReferenceWidth and ReferenceHeight into…
