神经网络变量筛选—基于BP的神经网络变量筛选

本文在确定了水声信道的数学描述后,提出了在信道自适应过程中,可以应用 子波对信号进行多分辨率分解,逐尺度地对信道进行均衡. 这样,不但减少了运算数 据量,也减少了均衡所需的权系数个数.(equalizer)

adaboost算法的matlab程序，随机生成正负样本，用adaboost进行分类(adaboost algorithm matlab program randomly generates positive and negative samples adaboost classification)

svm分类回归工具箱 适合初学者学习用()

在二维空间里有两个点A=(X1，Y1)和B=(X2，Y2)，如果X1>X2并且Y1>Y2 ，我们认为A优于B，A是这个集合的最大极值点，在给定的二维空间里的N个点的集合S中，找出最大极值点。(In two-dimensional space, there are two points = A = (X1, Y1) and B (X2, Y2), if the X1 and Y1 > X2 > Y2, we think that A is superior to B, A is the biggest extreme value point of the set, in A given set of N points in the two-dimensional space S, find out the most extreme value point.)

有井曲线作为输入可计算其地震波的衰减,基于互功率谱的时延估计，比较了软阈值，硬阈值及当今各种阈值计算方法。( There is a well attenuation curve as input to calculate its seismic waves, Based on the time delay estimation of power spectrum, Comparison of soft threshold and hard threshold and today various threshold calculation method.)

说明：  可以实现图片中的数字识别，并将识别之后的数字写入文本文件中，数字可以式多行，可以长度不同才可以(But realize the number recognition in the picture, and write the recognized number into the text file.)

说明：  数据整理，数据和标签和样本数量之间的匹配，当然也可以用其他方法，仅供参考(Data collation, matching between data and label and sample quantity, of course, other methods can be used, for reference only)

matlab控制利用stk进行实时仿真的连接指令以及一个stk现成的场景仿真(matlab control simulation using real-time connection stk instruction and a ready-made scene simulation stk)

基于matlab开发的建筑节能计算平台，可以计算角系数、热辐射换热，附带程序说明(Based on the development of building energy matlab computing platform, you can calculate the angle coefficient, thermal radiation heat transfer, with the program description)

说明：  地震勘探的必备工具。大家相互交流，请专业方面的朋友多多指教！(An indispensable tool for seismic exploration. U.S. mutual exchanges, please professional exhibitions Friend!)
