Hidden Markov Model predicting next observation

由 我怕爱的太早我们不能终老 提交于 2019-12-04 08:37:39
问题 I have a sequence of 500 observations of the movements of a bird. I want to predict what the 501st movement of the bird would be. I searched the web and I guess this can be done by using HMM, however I do not have any experience on that subject. Can anyone explain the steps of an algorithm used to solve this problem? 回答1: x1-x2-x3-x4-x5......x500-x501 | | | | | | y1 y2 y3 y4 y5 y500 x - actual state y - observations P(y_i|x_i) - how you think the observation depends on the actual state P(x_i

PHP - alternative to html hidden input

由 十年热恋 提交于 2019-12-04 04:47:43
问题 I need to resend a value from a previous html form in another form so that it can be used as part of a prepared SQL statement. However, I do not really want to use html hidden input due to potential security problems. Anyone know of another method? Thanks. 回答1: Temporarily save the values in a session. Hidden HTML inputs shouldn't cause any security problems though, as long as you properly validate them (again) before putting them in the database. 回答2: You can save it in the session, then the

I'm trying to get a script that works both in a native windows shell and a cygwin shell (via ssh) that prompts for and reads a password entered by the user.

Jquery getting a hidden element's height

由 我是研究僧i 提交于 2019-12-04 00:38:01
问题 I was trying to get a list of element's height value but it was returning 0. I've done some research and saw that in order get element's height, that element must be visible. But I want to check its height when it's hidden. If its height is bigger than some value use some functions then make it visible. Is there any way to do this? I mean: Check hidden element's height. If it has OK value make it visible. If it doesn't have required value do some functions. Make it visible. 回答1: You can show

Make hidden table column take no space in SSRS 2008 R2

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-03 22:33:47
Has anyone figured out a good way to make a hidden table/matrix column take no horizontal space? I could use some crazy conditionals to dynamically determine the contents of the columns (effectively sliding them leftward as far as possible), but that is nasty, plus doesn't allow for varying column widths in the columns to the right of the one I want to hide. The idea is that when a parameter is set to "Any" then the column with the corresponding value should display. But when the parameter is set to an explicit single value the report doesn't need to contain that column any more (it will be

Pull out div from right of screen

由 安稳与你 提交于 2019-12-03 21:23:23
Pull out a div from the left? Easy as pie. Pull it out from the right? Not so much. I am looking for a div to be hidden offscreen but connected to a small tag on screen. When the user clicks the tag, out slides the whole div. This is pretty basic from the left using jQuery and CSS. From the right though, a user can just scroll over to see the "hidden" div! Here is what I want ( http://jsfiddle.net/yHPTv/ ) except instead of the div being partially hidden offscreen-left, I want it partially hidden offscreen-right. Here is what I've tried so far ( http://jsfiddle.net/LU8En/ ), and obviously it

jQuery hover : fading in a hidden div while fading out the “default” one

由 最后都变了- 提交于 2019-12-03 21:14:02
I have two divs (one of them hidden with CSS), which I'm fading in and out in alternance inside a common space, on hover. This is the markup : <div id="wrap"> <div class="image"> <img src="http://domain.com/images/image.png"> </div> <div class="text hide"> <p>Text text text</p> </div> </div> And I was applying this jQuery code to fade out the image - and fading in the text, on hover : <script type="text/javascript"> $(function(){ $('#wrap').hover( function(){ $('#wrap .image').fadeOut(100, function(){ $('#wrap .text').fadeIn(100); }); }, function(){ $('#wrap .text').fadeOut(100, function(){ $(

方法一： .cl:after { visibility: hidden; display: block; font-size: 0; content: " "; clear: both; height: 0; } .cl { zoom: 1; /* for IE6 IE7 */ } 方法二： 1. .clearfloat {clear:both;height:0;font-size: 1px;line-height: 0px; overflow:hidden;} 好处 ：兼容性好不会出现奇怪的错位 缺点：在IE6 和IE7下父元素必须设置宽度才可以起作用 方法三： 2. .clear1 {overflow:auto;zoom:1;} 好处：代码简洁随用随拿，信手拈来。 缺点：容易出现奇怪的滚动框（很容易的哦~~！ 方法四： .clear{clear:both;height:0px;overflow:hidden;} 网易方案： .tab-con:after {clear:both;content: ".";display:block; height:0;overflow:hidden;visibility:hidden;} 新浪方案： .clearit {clear: both;} .clearfix:after { clear: both; content: "."
