通过快速傅里叶变换（Fast Fourier Trans-form，FFT）（Hanning窗函数，1s宽度和50%交迭比）提取alpha、beta、delta、theta波段在9个电极点上的功率谱密度值（Power Spectral Density，PSD），以及快慢波比率的数值（theta/betaratio，TBR；theta/alpharatio，TAR），为了进行归一化，对这些PSD数值取自然对数，然后计算9...
•It is a form of optical imaging used to measure superficial cortical hemodynamics. 它是一种使用光谱法测量大脑神经活动水平的神经成像方法。 关于近红外脑成像的原理可参看《近红外脑功能成像基础》和《光学近红外脑成像原理》 fNIRS是如何工作的?
At a given time instant the EEG data acquisition can be well approximated by a linear equation of the generic form $$ y = H(\theta)q + H_{\mathfrak{i}}(\theta_{\mathfrak{i}})q_{\mathfrak{i}} + H_{\mathfrak{b}}(\theta_{\mathfrak{b}}) q_{\mathfrak{b}} + n_{\ma...
“Source estimation” section). This results in a matrix of 4×Nssources for each IC projection, whereNsdenotes the total number of samples in the recorded EEG signal set. These matrices are generated for each IC projection and concatenated together to form a feature matrix of dimensions(4×M...
wheretran() represents the transpose operation and the\(E_{pos}\in {\mathbb {R}}^{C\times T}\)represents the position encoding. In this paper, we use the position encoding in the form of a trigonometric function at a fixed position.\(z^{s}_{0}\)denotes the representation with the...
