Preceptron – A simple binary classifier
What is a preceptron?
Suppose we have a linearly separable two-category dataset with an input space \mathcal{X}\subseteq\mathbb{R}^n
and a output spac[……]

上一篇提到FacenetEvo使用detect_face(PIL.Image img)方法实现MTCNN下PRO网络的面部识别,而我使用OpenCV得到的帧输入为CV::Mat格式,需要进行一次BGR to RGB的转换再转为PIL Image
其次是输出框选的图片的方法
这个方[……]
In Bayesian statistical inference, a prior probability distribution, often simply called the prior, of an uncertain quantity is the probability distri[……]
通过过MTCNN的三个子网络(Pnet, Rnet和Onet)进行人脸的精细识别
卷积是数分里一种重要的运算~
设: f(x), g(x)
是\mathbb{R}
上的两个可积函数, 作积分:
\int^\infty_{-\infty}{f(\tau)g(x-\tau)d\tau}

给定测试集P
, 其Shape为(M,D)
, 再给定训练集(N,D)
, 其Shape为(N,D)
.
令P_i
为P
的第i
行, 即P_i = [P_{i1}\space P_{i2}\space ··· \space P_{iD}]
, 同理C_j=[C_{j1}\space C_{j2}\space ·[......]
