In this demo, I use the EM algorithm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: Nando de Freitas, Mahesan Niranjan and Andrew Gee Nonlinear State Space Estimation with Neural Networks and the EM algorithm After downloading the file, type "tar -xf EMdemo.tar" to uncompress it. This creates the directory EMdemo containing the required m files. Go to this directory, load matlab5 and type "EMtremor". The figures will then show you the simulation results, including ROC curves, likelihood plots, decision boundaries with error bars, etc. WARNING: Do make sure that you monitor the log-likelihood and check that it is increasing. Due to numerical errors, it might show glitches for some data sets.

遗传模糊优化算法，对大量信号的处理算法希望对大家研究有帮助。 (Fuzzy genetic optimization algorithm, the algorithm is useful for everyone to want to help.)

本例用matlab语言实现了4QPSK的编解码及通过awgn信道的仿真。采用蒙特卡罗仿真法，得到误码性能，绘制曲线。可用于算法研究或课程学习。(Matlab language used in this case achieved 4QPSK codec and channel through awgn simulation. Monte Carlo simulation method, the BER performance, drawing curves. Algorithm can be used for research or courses.)

Speech Recognition with TDNN(Time delay neural network)

由于飞机设计是一个需要多次反复迭代的重复过程，需要进行大量的计算，因此我们自己编写了一些MATLAB程序。(As the aircraft design is a repeated duplication of iterative process, requiring a large number of calculation, so we have written a number of MATLAB procedures.)
