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.

The last step in training phase is refinement of the clusters found above. Although DynamicClustering counters all the basic k-means disadvantages, setting the intra-cluster similarity r may require experimentation. Also, a cluster may have a lot in common with another, i.e., sequences assigned to it are as close to it as they are to another cluster. There may also be denser sub-clusters within the larger ones.

This document provides guidelines and describes how to easily port S60 2nd Edition C++ applications to S60 3rd Edition. The document has been written based on experiences of porting regular S60 2nd Edition applications, such as the S60 Platform: POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from the example are shown in Chapter 8, “Application build changes,” and in Appendix A, “Code example." In addition, Appendix B, "Commonly used functions that require capabilities," and Appendix C, "Commonly used interfaces that have been changed or removed," provide useful information on some frequently used functions and interfaces in third-party applications.

tensor 向量的推廣。在一個坐標系下，由若干個數（稱為分量）來表示，而在不同坐標系下的分量之間應滿足一定的變換規則，如矩陣、多變量線性形式等。一些物理量如彈性體的應力、應變以及運動物體的能量動量等都需用張量來表示。在微分幾何的發展中，C.F.高斯、B.黎曼、E.B.克里斯托費爾等人在19世紀就導入了張量的概念，隨后由G.里奇及其學生T.列維齊維塔發展成張量分析，A.愛因斯坦在其廣義相對論中廣泛地利用了張量。

This article presents GISCoordinate.java - a class that allows you to represent a GIS coordinate in your JAVA code in decimal degrees (38.4443, e.g. 122.33433) , minute degrees (33 44 22E, 122 33 44N), or radian degrees. Also, you can use this class to manipulate the coordinate, moving it around the globe by giving it distances in feet and direction of travel. You can then extract the new coordinate that is calculated after the travel.

We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fields, so that the anisotropy ratio tends to infinity, the D and B fields blow up near the cloaking surface. Since the metamaterials used to implement cloaking are based on effective medium theory, the resulting large variation in D and B will pose a challenge to the suitability of the field averaged characterization of " and 碌. We also consider cloaking with and without the SHS (softand- hard surface) lining, shown in [6] to be theoretically necessary for cloaking in the cylindrical geometry. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of D and B prevented.
