EMfor_neural_networks
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.

本程序是用Q值法求得的关于席位的分配问题,
并对最结果进行了一定的考虑,是否公平,公平程度如何。(This program is to use Q value method about optimal seats, the allocation of
And the results were certain consideration, whether fair, fair to what extent.

myFDTD01
FDTD Finite-Difference Time-domain in free space no ABC
FDTD(t) runs FDTD for time t.
FDTD implements the FDTD/staggered leapfrog scheme
over time 0-max_time and space 0-max_space. This program
simulates a gaussian pulse in the grid specified with
max_time and max_space. The pulse is sent from the center of
the problem space and disperses in both directions
