Given a sequence {xn} with n ∈ [0, N − 1], the discrete Fourier Transform (DFT) is defined by the formula: 傅里叶变换将函数分解为其组成频率。 给定一个 n ∈ [0, N − 1] 的序列 {xn},离散傅里叶变换 (DFT) 由以下公式定义: X_k = \sum_{0}^{N-1}{x_ne^{-\frac{2...
The calculation formula of the metric is as follows: (4) where TP denotes true positive rate, FP denotes false positive rate, and FN denotes false negative rate. 4. Experimental Results On the CIFAR-10 dataset, Tables 6–8 show the precision and recall scores of different detection methods...
