MATLAB图像处理:136:使用可解释的单类分类神经网络检测图像异常 本示例展示了如何训练一个异常检测器来对药丸图像进行视觉检查。 在单类异常检测方法中,训练是半监督的,这意味着网络对仅由没有异常的正常图像组成的数据进行训练[1]。尽管仅对正常场景的样本进行了训练,但该模型学习了如何区分正常场景和异常场景。单类学习为异常检测
Otherwise, k is a column vector. k is an empty row vector or empty column vector when X is an empty array or has no nonzero elements. find uses the convention that k is an empty matrix [] when X is an empty matrix []. You can return the nonzero values in X using X(k). ...
If the'rows'flag is not specified, thenCis a column vector unless bothAandBare row vectors, in which caseCis a row vector. For example,setxor([],[1 2])returns a column vector. If the'rows'flag is specified, thenCis a matrix containing the rows ofAandBthat are not in the intersecti...
Ifdimis equal to 2, thennanmean(X,2)returns a column vector containing the mean for each row. Ifdimis greater thanndims(X)or ifsize(X,dim)is 1, thennanmeanreturnsX. Data Types:single|double Vector of dimensions, specified as a positive integer vector. Each element ofvecdimrepresents a ...
The direct term vector is empty iflength(b)<length(a); otherwise length(k) = length(b)-length(a)+1 Ifp(j) = ... = p(j+m-1)is a pole of multiplicitym, then the expansion includes terms of the form rjs−pj+rj+1(s−pj)2+…+rj+m−1(s−pj)m. ...

In Matlab it is often convenient to ignore the convention that the initial form of a vector is a column; the user can define the initial form of a vector as a row or a column. The implementation of vector and matrix multiplication in Matlab is straightforward. Beginning with vector ...
k = find(X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. examp...
