LogReg
逻辑回归实现线性分类器,文件中的readme.txt可以看到使用方法。
具体使用就是通过data.txt读入数据(默认2维数据,分为正反两类。)然后用matlab运行solve.m即可得到分类线、分类准确率。(a matlab source code for Logistic Regression. Datas in data.txt are of 2dimension and 2 types. run solve.m in matlab software to get the accuracy and the plot result.)

A1Jedi.java
This program counts the occurrence of specified patterns in the input strands and produces a report for each pattern. The first input to this program will be an integer indicating how many patterns will be provided (call this N). The next N words to this program will be patterns of nucleobases to search for. Following the patterns will be a sequence of strands terminated by the word "end" as before.

DFT进行频谱分析时的三种现象
1、混叠:对连续信号采样,要求连续信号是带限的,采样频率要足够高。Fs应满足Nyquist采样定理才不产生混叠。
采样前加低通滤波器防混叠
2、频谱泄漏:DFT对时域信号进行了截断(相当于采样信号乘了一个窗函数),时域的乘积相当于频域卷积,改变了原信号频谱。
改用其他窗函数(非矩形)改善泄漏。
3、栅栏现象:DFT 只给出了频谱在采样点上的取值,采样点间的频谱内容丢失。(DFT spectrum analysis of a three phenomena, aliasing : continuous signal sampling, requiring continuous signal is band-limited, the sampling frequency should be high enough. Fs meet the Nyquist Sampling Theorem would not have aliasing. Sampling former low-pass filter plus anti-aliasing 2, spectrum leakage : DFT right time domain signal a disconnect (equivalent to a sampling signal by a window function). time domain is equivalent to the product of frequency-domain convolution, changes in the spectrum of the original signal. Window functions to switch to other (non-rectangular) to improve leakage. 3, fenced phenomenon : DFT spectrum is given only at the sampling point value, sampling points of the spectrum as lost.)
