  • Estimate gaussian (mixture) density from a set of weighted samples

    - by Christian
    Assume I have a set of weighted samples, where each samples has a corresponding weight between 0 and 1. I'd like to estimate the parameters of a gaussian mixture distribution that is biased towards the samples with higher weight. In the usual non-weighted case gaussian mixture estimation is done via the EM algorithm. Does anyone know an implementation (any language is ok) that permits passing weights? If not, does anyone know how to modify the algorithm to account for the weights? If not, can some one give me a hint on how to incorporate the weights in the initial formula of the maximum-log-likelihood formulation of the problem? Thanks!

    - by Josh
    A friend of mine wants to make her favicon visible when people user Google Reader to view the RSS of her Wordpress blog. Anyone have a quick tip on how / where to make that reference? Her current web host is Bluehost, and apparently that is the "icon" people see when using Google Reader. Any suggestions would be helpful.

  • DynamicMethod NullReferenceException

    - by Jeff
    Can anyone tell me what's wrong with my IL code here? IL_0000: nop IL_0001: ldarg.1 IL_0002: isinst MyXmlWriter IL_0007: stloc.0 IL_0008: ldloc.0 IL_0009: ldarg.2 IL_000a: ldind.ref IL_000b: unbox.any TestEnum IL_0010: ldfld Int64 value__/FastSerializer.TestEnum IL_0015: callvirt Void WriteValue(Int64)/System.Xml.XmlWriter IL_001a: nop IL_001b: ret I'm going crazy here, since I've written a test app which does the same thing as above, but in C#, and in reflector the IL code from that looks just like my DynamicMethod's IL code above (except my test C# app uses a TestStruct with a public field instead of the private value field on the enum above, but I have skipVisibility set to true)... I get a NullReferenceException. My DynamicMethod's signature is: public delegate void DynamicWrite(IMyXmlWriter writer, ref object value, MyContract contract); And I'm definitely not passing in anything null. Thanks in advance!

  • Manipulating pixels using only toDataURL

    - by Chris
    The problem I have is this: I need to be able to dynamically tint an image using Javascript, but I cannot access pixel data via the canvas. I can, however, store the dataURL (or any other text-based data format) and include that with the code, manipulate that data, and then create an image object using that dataURL. My question is, how can I access the RGBA value of each pixel, given only the dataURL. I assume I need to decode the base64 url, but into what format in order to manipulate on the pixel level? And then would be it be as trivial as re-encoding it as base64, slapping it in a url, and the passing to an image? Thanks.

  • Parsing a DateTime containing milliseconds fails for certain cultures. Why?

    - by dradovic
    I'm trying to parse a string containing milliseconds like this: string s = "11.05.2010 15:03:08.7718687"; // culture: de-CH DateTime d = DateTime.Parse(s); // works However, for example under the de-DE locale, the decimal separator is a comma (not a dot). So the example becomes: string s = "11.05.2010 15:03:08,7718687"; // culture: de-DE (note the comma) DateTime d = DateTime.Parse(s); // throws a FormatException It is weird to me that DateTime.Parse(s) should throw a FormatException now as it is supposed to use the CultureInfo.CurrentCulture to do the parsing. Even passing the CurrentCulture as an argument explicitly does not help neither. Does anybody have an idea why this does not work? Doesn't parsing take the NumberFormatInfo.NumberDecimalSeparator into account?

  • Load WPF styles (static resources) from an external assembly

    - by Shimmy
    I have a few WPF applications and I want all my styles to be in a shared assembly instead of declaring them in each application separately. I am looking for a way so I don't have to change all my Style="{StaticResource BlahBlah}" in the existing applications; I just want to add the reference to this style assembly, and delete it from the current application, so it's taken from the assembly. Is there any way?

Transaction is an interface, I have to entity classes that implement it, I want on HQL query to return a Collection of type Transaction.

  • Pass associative arrays in call_user_func_array(...)

    - by Matt
    Hey all, I'm building a templating system and I'm running in to an issue with calling functions on the fly. When I try the following: $args = array( 4, 'test' => 'hello', 'hi' ); You know.. some numerical elements some associative elements, call_user_func_array($function, $args); converts the array to something like this: $args = array( 4, 'hello', 'hi' ); Is there any way around this other than passing an array like this: $args = array( 4, array('test' => 'hello'), 'hi' ); Thanks! Matt

  • Creating share programmatically fails with error 9

    - by Christopher
    Directory.CreateDirectory("C:\MyTestShare") Dim managementClass As New ManagementClass("Win32_Share") Dim inParams As ManagementBaseObject = managementClass.GetMethodParameters("Create") inParams.Item("Description") = "My Files Share" inParams.Item("Name") = "My Files Share" inParams.Item("Path") = "C:\MyTestShare" inParams.Item("Type") = 0 If (DirectCast(managementClass.InvokeMethod("Create", inParams, Nothing).Properties.Item("ReturnValue").Value, UInt32) <> 0) Then Throw New Exception("Unable to share directory.") End If I am using the following code to set up a share, but I am always getting a return value of 9 which means invalid name. I am passing a string and have tried to use an explicit string and I still get error 9. I am creating the share remotely rather than on local machine however. Not sure if that matter.

  • PHP Menu Question

    - by Vecta
    As one of the steps toward a greater website redesign I am putting the majority of the content of our website into html files to be used as includes. I am intending on passing a variable to the PHP template page through the URL to call the proper include. Our website has many programs that each need an index page as well as about 5 sub-pages. These program pages will need a menu system to navigate between the different pages.I am naming the pages pagex_1, pagex_2, pagex_3, etc. where "pagex" is descriptive of the page content. My question is, what would be the best way to handle this menu system? Is there a way to modify the initial variable used to arrive at the index page to create links in the menu to arrive at the other pages? Thanks for any help!

  • Simplest way to match array of strings to search in perl?

    - by Ben Dauphinee
    What I want to do is check an array of strings against my search string and get the corresponding key so I can store it. Is there a magical way of doing this with Perl, or am I doomed to using a loop? If so, what is the most efficient way to do this? I'm relatively new to Perl (I've only written 2 other scripts), so I don't know a lot of the magic yet, just that Perl is magic =D Reference Array: (1 = 'Canon', 2 = 'HP', 3 = 'Sony') Search String: Sony's Cyber-shot DSC-S600 End Result: 3

  • car parking management software development

    - by George2
    Hello everyone, I am planning to develop a car parking management software (for a car parking company). I am currently in the planning phase. I am wondering whether there are any existing/popular car parking management software/platform/companies -- so that maybe I can make some reference from them or buy them directly? :-) Appreciate if the referred materials are based on Windows technolgoies, but not a must. thanks in avdance, George

  • Working with anonymous modules in Ruby

    - by Byron Park
    Suppose I make a module as follows: m = Module.new do class C end end Three questions: Other than a reference to m, is there a way I can access C and other things inside m? Can I give a name to the anonymous module after I've created it (just as if I'd typed "module ...")? How do I delete the anonymous module when I'm done with it, such that the constants it defines are no longer present?

  • Grails pattern to reuse template on error

    - by bsreekanth
    Hello, I have a gsp template, where the data for create view is passed through the controller. def create = { def bookInstance = new Book() bookInstance .properties = params def map = getDefaultValues() render(template: "create", model: [bookInstance : bookInstance , title: map.title, somelist: somelist ....]) the gsp template <g:select optionKey="id" from="${somelist}" name="somelist.id" value="${bookInstance ?.somelist?.id}" noSelection="['null': '']"></g:select> now, in the save method, if there is an error, it returns currently populated and validated instance (default scaffold implementation) render(template: "create", model: [bookInstance : bookInstance ]) But the fields in the gsp (error page rendered from save action) is empty. I could see the reason as it looks the value in "${somelist}" , but it is not used in save method. Do i just need to check for null in the gsp and use whichever map is available, or any better method (passing all the map in the save method is not an option) .. thanks in advance..

  • Potential for SQL injection here?

    - by Matt Greer
    This may be a really dumb question but I figure why not... I am using RIA Services with Entity Framework as the back end. I have some places in my app where I accept user input and directly ask RIA Services (and in turn EF and in turn my database) questions using their data. Do any of these layers help prevent security issues or should I scrub my data myself? For example, whenever a new user registers with the app, I call this method: [Query] public IEnumerable<EmailVerificationResult> VerifyUserWithEmailToken(string token) { using (UserService userService = new UserService()) { // token came straight from the user, am I in trouble here passing it directly into // my DomainService, should I verify the data here (or in UserService)? User user = userService.GetUserByEmailVerificationToken(token); ... } } (and whether I should be rolling my own user verification system is another issue altogether, we are in the process of adopting MS's membership framework. I'm more interested in sql injection and RIA services in general)

  • What exactly are administrative redexes after CPS conversion?

    - by eljenso
    In the context of Scheme and CPS conversion, I'm having a little trouble deciding what administrative redexes (lambdas) exactly are: all the lambda expressions that are introduced by the CPS conversion only the lambda expressions that are introduced by the CPS conversion but you wouldn't have written if you did the conversion "by hand" or through a smarter CPS-converter If possible, a good reference would be welcome.

  • StackOverflowException in c# when no local variable in the function

    - by dnkulkarni
    when i do this static void Main() { Main(); } I receive stackoverflow exception. As i have read so far about C# they say ONLY local variable of value types (and short living ones) will go on stack. But here in the code there are no local variable to go on stack then what overflows it ? I know from assembly code line Perspective that reference to Main() will go on stack too ? Is that right ?

    - by Stan
    If open yahoo finance chart in IE, the chart will be resized to fit the viewing window, and making the chart viewable without scrolling down. However, this makes the chart become smaller for me. I would like to see original size, which requires me to click the setting bar and change something to make it restore original size. The chart shows original size in Chrome. Is it possible to view original size in IE by passing some parameters in url? I was trying looking into source code but found nothing.

  • COM Pointers and process termination

    - by Tony
    Can an unreleased COM pointer to an external process (still alive) cause that process to hang on destruction? Even with TerminateProcess called on it? Process A has a COM interface pointer reference to Process B, now Process B issues a TerminateProcess on A, if some COM interface pointer to Process B in Process A is not released properly, could it be that the process hangs on termination?

  • .NET - downloading multiple pages from a website with a single DNS query

    - by lampak
    I'm using HttpRequest to download several pages from a website (in a loop). Simplifying it looks like this: HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create( "http://sub.domain.com/something/" + someString ); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); //do something I'm not quite sure actually but every request seems to resolve the address again (I don't know how to test if I'm right). I would like to boost it a little and resolve the address once and then reuse it for all requests. I can't work out how to force HttpRequest into using it, though. I have tried using Dns.GetHostAddresses, converting the result to a string and passing it as the address to HttpWebRequest.Create. Unfortunately, server returns error 404 then. I managed to google that's probably because the "Host" header of the http query doesn't match what the server expects. Is there a simple way to solve this?
