EEG信号特征提取(PSD)

因为刚入门做EEG情感数据分析,所以对特征提取存在一些困扰,具体在于使用spectrogram计算PSD后,如何提取特定频域带的PSD呢?是计算平均power(用bandpower)吗? 具体问题如下: 如果对于一段采样频率是200Hz的信号,使用256点的STFT,windows为1s的Hanning,且没有overlap进行提取PSD的MATLAB代码是否应该这么写: [s,f,t,p]=spectrogram(data,hanning(200),0,256,200); 后续如何对提取特定频域带的PSD呢?如果提取的话提取什么内容呢?是平均值还是累加值呢? 还有一个问题是有些文献使用welch's methods来提取PSD,pwelch和spectrogram的区别是什么?为什么对于同一段信号,使用不同方法,结果完全不同呢?

Fillword

Alex likes solving fillwords. Fillword is a word game with very simple rules. The author of the fillword takes rectangular grid (M cells width, N cells height) and P words. Then he writes letters in the cells of the grid (one letter in one cell) so that each word can be found on the grid and the following conditions are met: > no cell belongs to more than one word >no cell belongs to any word more than once Some word W (let us consider its length being k) is found on the grid if you can find such sequence of cells (x1, y1), (x2, y2), .., (xk, yk) that: >(xi, yi) and (xi+1, yi+1) are neighbors (|xi-xi+1| + |yi-yi+1| = 1) for each i = 1, 2, ��, k-1 > W[i] is written in the cell with coordinates (xi, yi). The task is to find all the words on the grid. After they are found, you see that the letters in some cells are not used (they do not belong to any found word). You make up a secret word using these letters and win a big prize. To make things clear, let us consider the following example (the words are BEG and GEE): Your task is to help Alex to solve fillwords. You should find out which letters will be left after he finds all the words on the grid. The most difficult task - to make up a secret word out of them - we still reserve to Alex. Input The first line of the input file contains three integer numbers - N, M (2 <= M, N <= 10) and P (P <= 100). Next N lines contain M characters each, and represent the grid. The following P lines contain words that are to be found on the fillword grid. Fillword will always have at least one solution. All characters occurring in fillword will be capital English letters. Process to the end of file. Output Output letters from, which a secret word should be made up. Letters should be output in lexicographical order.

Delta Wave 波形的问题

Problem Description A delta wave is a high amplitude brain wave in humans with a frequency of 1 – 4 hertz which can be recorded with an electroencephalogram (EEG) and is usually associated with slow-wave sleep (SWS). -- from Wikipedia The researchers have discovered a new kind of species called "otaku", whose brain waves are rather strange. The delta wave of an otaku's brain can be approximated by a polygonal line in the 2D coordinate system. The line is a route from point (0, 0) to (N, 0), and it is allowed to move only to the right (up, down or straight) at every step. And during the whole moving, it is not allowed to dip below the y = 0 axis. For example, there are the 9 kinds of delta waves for N = 4: Given N, you are requested to find out how many kinds of different delta waves of otaku. Input There are no more than 20 test cases. There is only one line for each case, containing an integer N (2 < N <= 10000) Output Output one line for each test case. For the answer may be quite huge, you need only output the answer module 10100. Sample Input 3 4 Sample Output 4 9
