  • Classification of relationships in words?

    - by C.
    Hi, I'm not sure whats the best algorithm to use for the classification of relationships in words. For example in the case of a sentence such as "The yellow sun" there is a relationship between yellow and sun. THe machine learning techniques I have considered so far are Baynesian Statistics, Rough Sets, Fuzzy Logic, Hidden markov model and Artificial Neural Networks. Any suggestions please? thank you :)

  • Deleting items from a ListView using a custom BaseAdapter

    - by HXCaine
    I am using a customised BaseAdapter to display items on a ListView. The items are just strings held in an ArrayList. The list items have a delete button on them (big red X), and I'd like to remove the item from the ArrayList, and notify the ListView to update itself. However, every implementation I've tried gets mysterious position numbers given to it, so for example clicking item 2's delete button will delete item 5's. It seems to be almost entirely random. One thing to note is that elements may be repeated, but must be kept in the same order. For example, I can have "Irish" twice, as elements 3 and 7. My code is below: private static class ViewHolder { TextView lang; int position; } public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.language_link_row, null); holder = new ViewHolder(); holder.lang = (TextView)convertView.findViewById(R.id.language_link_text); holder.position = position; final ImageView deleteButton = (ImageView) convertView.findViewById(R.id.language_link_cross_delete); deleteButton.setOnClickListener(this); convertView.setTag(holder); deleteButton.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.lang.setText(mLanguages.get(position)); return convertView; } I later attempt to retrieve the deleted element's position by grabbing the tag, but it's always the wrong position in the list. There is no noticeable pattern to the position given here, it always seems random. // The delete button's listener public void onClick(View v) { ViewHolder deleteHolder = (ViewHolder) v.getTag(); int pos = deleteHolder.position; ... ... ... } I would be quite happy to just delete the item from the ArrayList and have the ListView update itself, but the position I'm getting is incorrect so I can't do that. Please note that I did, at first, have the deleteButton clickListener inside the getView method, and used 'position' to delete the value, but I had the same problem. Any suggestions appreciated, this is really irritating me.

  • Python regex help

    - by Dormish
    I am trying to make a regex that finds all names, url and phone numbers in an html page. But I'm having trouble with the phone number part. I think the problem with the numbers part is that is searches until it finds the </strong> but in that process it skips people, instead of making a empty string if the person has no phone number ( simply put instead of a list like this: url1+name1+num1 | url2+name2+"" | url3+name3+num3 it returns a list like this: url1+name1+num1 | url2+name2+num3 , with url3+name3 deleted in the process) for url, name, pnumber in re.findall('Name"><div>(?:<a href="/si([^">]*)"> )?([^<]*)(?:.*?</strong>([^<]*))?',page): I am searchin for people in s single very long line. A person could have an url or phone number. An example of a person with an url and a phone number <tr> <td class="lablinksName"><div><a href="/si/ivan-bratko/default.html"> dr. Ivan Bratko akad. prof.</a></div></td> <td class="lablinksMail"><a href="javascript:void(cmPopup('sendMessage', '/si/ivan-bratko/mailer.html', true, 350, 350));"><img src="/Static/images/gui/mail.gif" height="8" width="11"></a></td> <td class="lablinksPhone"><div><strong>T:</strong> +386 1 4768 393 </div></td> </tr> And an example of a person with no url or phone number <tr> <td class="lablinksName"><div> dr. Branko Matjaž Juric prof.</div></td> <td class="lablinksMail"><a href="javascript:void(cmPopup('sendMessage', '/si/branko-matjaz-juric/mailer.html', true, 350, 350));"><img src="/Static/images/gui/mail.gif" height="8" width="11"></a></td> <td class="lablinksPhone"><div> </div></td> </tr> I hope i was clear enough and if any one can help me.

  • Java -Xms initial size effects

    - by SyBer
    Hi. What is the benefit of setting the -Xms parameter, and having the initial memory larger for example, then the default calculated one (64 MB in my case, according to Java GC tunning: http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html#par_gc.ergonomics.default_size)? Also, is there any good to setting both the initial and maximum memories to same size? Thanks.

  • How can i estimate memory usage of stl::map?

    - by Drakosha
    For example, I have a std::map with known sizeof(A) and sizefo(B), while map has N entries inside. How would you estimate its memory usage? I'd say it's something like (sizeof(A) + sizeof(B)) * N * factor But what is the factor? Different formula maybe? Update: Maybe it's easier to ask for upper bound?

  • .NET: Interface Problem VB.net Getter Only Interface

    - by snmcdonald
    Why does an interface override a class definition and violate class encapsulation? I have included two samples below, one in C# and one in VB.net? VB.net Module Module1 Sub Main() Dim testInterface As ITest = New TestMe Console.WriteLine(testInterface.Testable) ''// Prints False testInterface.Testable = True ''// Access to Private!!! Console.WriteLine(testInterface.Testable) ''// Prints True Dim testClass As TestMe = New TestMe Console.WriteLine(testClass.Testable) ''// Prints False ''//testClass.Testable = True ''// Compile Error Console.WriteLine(testClass.Testable) ''// Prints False End Sub End Module Public Class TestMe : Implements ITest Private m_testable As Boolean = False Public Property Testable As Boolean Implements ITest.Testable Get Return m_testable End Get Private Set(ByVal value As Boolean) m_testable = value End Set End Property End Class Interface ITest Property Testable As Boolean End Interface C# using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace InterfaceCSTest { class Program { static void Main(string[] args) { ITest testInterface = new TestMe(); Console.WriteLine(testInterface.Testable); testInterface.Testable = true; Console.WriteLine(testInterface.Testable); TestMe testClass = new TestMe(); Console.WriteLine(testClass.Testable); //testClass.Testable = true; Console.WriteLine(testClass.Testable); } } class TestMe : ITest { private bool m_testable = false; public bool Testable { get { return m_testable; } private set { m_testable = value; } } } interface ITest { bool Testable { get; set; } } } More Specifically How do I implement a interface in VB.net that will allow for a private setter. For example in C# I can declare: class TestMe : ITest { private bool m_testable = false; public bool Testable { get { return m_testable; } private set //No Compile Error here! { m_testable = value; } } } interface ITest { bool Testable { get; } } However, if I declare an interface property as readonly in VB.net I cannot create a setter. If I create a VB.net interface as just a plain old property then interface declarations will violate my encapsulation. Public Class TestMe : Implements ITest Private m_testable As Boolean = False Public ReadOnly Property Testable As Boolean Implements ITest.Testable Get Return m_testable End Get Private Set(ByVal value As Boolean) ''//Compile Error m_testable = value End Set End Property End Class Interface ITest ReadOnly Property Testable As Boolean End Interface So my question is, how do I define a getter only Interface in VB.net with proper encapsulation? I figured the first example would have been the best method. However, it appears as if interface definitions overrule class definitions. So I tried to create a getter only (Readonly) property like in C# but it does not work for VB.net. Maybe this is just a limitation of the language?

  • Using MOA to classify new examples?

    - by Sam Zetoloth
    I'm trying to use the java machine learning library MOA to train on a training data stream, then predict classes for a test data stream. The first part works fine, using (for example) java -cp .:moa.jar:weka.jar -javaagent:sizeofag.jar moa.DoTask "LearnModel -l MajorityClass -s (ArffFileStream -f atrain.arff -c -1) -O amodel.moa" But then I cannot figure out how to use the trained model (amodel.moa) on another stream (atest.arff) to predict the classes. Has anyone done this before?

  • Multiple config files for spring security

    - by Xabier
    Hello all, I'm quite new to all things spring, and right now I'm developing an application that uses Spring, Spring MVC and Srping Security. My problem is that I'm using two dispatcher servlets, one for /csm/*.html and another one for *.html and I'd like to have one spring security configuration file per servlet. Is this possible at all?, if so, could you point me to an example?. Thanks in advance, Xabier.

  • Error when using Java String split

    - by Dan Howard
    HI All, I've been using the basic split for a while - where I just parse out a string into an array based on a simple token like " " or ",". So of course a customer tries this: \\.br\ which fails miserably. I need to parse to an array of lines. The string for example looks like this: "LINE 1\\.br\\LINE 2\\.br\\LINE 3\\.br\\LINE 4\\.br\\" and this fails with java.util.regex.PatternSyntaxException: Unexpected internal error. Any ideas?

  • Custom reports for Hudson CI

    - by Valera Kolupaev
    Hello. My past CI experience is tightly coupled with CC.Net, but for sake of innovations I want to try Hudson server as CI Server. I wondering, is there a possibility to embed into build report custom reports, by transforming XSLT output of various tools that runs on CI? For example, I have hand-made IIS Log parser, that outputs XML, is it possible to include it's result into build log and fail build on certain condition?

  • Weak References and Disposable objects.

    - by Steve Sheldon
    In C# it is possible to create weak references to objects as described here: WeakReference Class In .net some classes also implement the IDisposable interface. Calling the Dispose method of this interface is performed to manually dispose of any managed or unmanaged resources currently being held onto. An example might be a Bitmap object or class. If I assign an object that implements IDisposable to a weak reference, will Dispose be called if the weak reference collects the object?

  • Developing Windows (Vista/7) Gadgets

    - by John
    Apart from seeming a few, I don't know much about how gadgets work. Are they special applications, or regular apps with special styled windows? I can't think of any app I use which has asked me if I want to install a gadget... I'd have thought any application which is typically left running all the time would be suitable... Skype/MSN for example. Am I misunderstanding the point of gadgets, or are they not popular?

  • Convert in memory POCO objects to c# code to initialize

    - by sidesinger
    Is there a library or code sample for converting an in memory POCO c# object to a .cs code file that creates that object. An example: object of type car in memory becomes: Car c = new Car { Name = "mazda", Id = 5, Passengers = new List<string> { "Bob", "Sally" } // etc... recursing to the bottom }; I could assume it could only set public properties.

    - by metal-gear-solid
    for big website's CSS what we should use IE condition sheets ( IE6, IE7, IE8 if needed) or CSS hacks in multiple people environment? and CSS will be handled by multiple people. I'm thinking to use hacks with proper comments because there are chanceh to forgot for other to make any changes in both css. For example : #ab { width:200px} in main css and #ab { width:210px} in IE css. Need your view on this. Thanks in advance.

  • XQuery method question, trying to sum values read from xml

    - by Buck
    I'm pretty new to XQuery and I'm trying to write an example function that I can't get to work. I want to read an xml file, parse out the "time" values, sum them as they're read and return the sum. This is trivial and I'm looking to build more functionality into it but I'd like to get this working first. Also, I know there's a "sum" directive in XQuery that would do just this but I want to add more to it so the built-in sum is insufficient for my needs. Here's my funtion: bool example(Zorba* aZorba) { XQuery_t lQuery = aZorba-compileQuery( "for $i in fn:doc('/tmp/products.xml')//time" "let $sum := xs:integer($i)" " return $sum" ); DynamicContext* lCtx = lQuery-getDynamicContext(); lCtx-setContextItemAsDocument("temp_measurements.xml", lDocStream); try { std::cout << lQuery << std::endl; } catch (DynamicException& e) { std::cerr << e.getDescription() << std::endl; return false; } catch (StaticException& f){ std::cerr << f.getDescription() << f.getErrorCodeAsString(f.getErrorCode()) << std::endl; return false; } } It's called with an appropriate main(). If I comment out the line that starts "let $sum..." then this works in that it returns the time values as a series of integers like this: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3.... Input file looks like this: <?xml version="1.0" encoding="UTF-8"? <temps <temp <time0</time <lat0</lat <long0</long <value0</value </temp <temp <time1</time <lat0</lat <long1</long <value0</value </temp ...

  • How to show printer properties/preferences dialog?

    - by Patrick Klug
    I can't figure out how to properly show the printer preference dialog of a given printer so that the user can change the printer settings. Most of the examples that I can find online manage to show the dialog but any changes the user might make are lost which makes it useless. Example: http://www.codeproject.com/KB/system/PrinterPropertiesWindow.aspx (I tried to change the code as suggested by BartJoy but that didn't fix it) Does anyone know how to do this properly?

  • Absolute reRendering using RichFaces

    - by wheelie
    Hey there, I am implementing copy/paste functionality for a complex object tree, this means you can copy an object and paste it where the object type is the same. Therefore I need to reRender the <a4j:commandLink>-s which are performing the paste action (so it will show on the GUI or not). Simplified example: Problem is that copy links are deep in the tree. How is it possible to reRender on a higher level in the component tree? (very)Simplified example: ... <h:form id="form1"> ... <a4j:commandLink value="Copy" reRender=":paste1, :paste2, :paste3" /> <a4j:commandLink id="paste1" value="Paste" rendered="#{myBean.myHashMap.key}" /> <a4j:outputPanel> <a4j:region renderRegionOnly="true"> <a4j:commandLink value="Copy" reRender=":paste1, :paste2, :paste3" /> <a4j:commandLink id="paste2" value="Paste" rendered="#{myBean.myHashMap.key}" /> </a4j:region> <a4j:outputPanel> <a4j:region renderRegionOnly="true"> <a4j:commandLink value="Copy" reRender=":paste1, :paste2, :paste3" /> <a4j:commandLink id="paste3" value="Paste" rendered="#{myBean.myHashMap.key}" /> </a4j:region> </a4j:outputPanel> </a4j:outputPanel> ... </h:form> Something like that. In practise this differs in that a rich:tree is displayed. Also, there can be multiple instances of the same paste link: object:0::paste3, object:1::paste3. private final String pasteIDs = ":xxPaste, ... , :xyPaste"; According to the RichFaces reference, putting the separator to the beginning of the ID means it is an "absolute" search expression, however this way i get the same result: only the 'local' paste link gets rerendered, the others not. Every copy-paste link pair is encapsulated in <a4j:region renderRegionOnly="true">, because it is necessary for other components to restrict the reRender to that region. Could this be blocking the reRender I want to make? Also I want to rerender exactly those paste links, so no other rerender action is triggered. Hope it is clear what i want to achieve. Any help would be appreciated! Daniel

  • Do your admins modify your web.config files?

    - by mcass20
    I'm wondering how other developers are handling source code conflicts for config files when system admins modify them in production. For example, if a system admin updates a appsettings key on the production server and then my team publishes out a project, it will overwrite that key. How do you handle config file updates in your organization?

  • What's the point of some of shoulda's macros?

    - by ryeguy
    I think shoulda is really neat, but what I don't understand is why some of the macros exist, such as: should_validate_uniqueness_of :title should_validate_presence_of :body, :message => /wtf/ should_validate_presence_of :title should_validate_numericality_of :user_id I'm relatively new to testing, but what purpose do these serve? They're almost an exact mirror of the same validations that happen in the model. For example, what exactly do you accomplish by going into your model and writing validates_uniqueness_of :title and then writing a test that says should_validate_uniqueness_of :title?

  • To synchronise css styles in a browser and on a server.

    - by kalininew
    Prompt, please: whether it is possible in general from a browser (for example using firebug in firefox) to edit css a file on a server? I heard that there is an addition to firefox for connection on FTP (FireFTP). It is possible to change styles on page in firebug. Whether it is impossible to "combine" them - you change css styles in firebug, and they varies on a server? Who can heard about such miracle (not necessarily for firefox, suddenly for chrome there is such piece).

    For the longest time I've been curious to code in Intermediate Language just as an academic endeavour and to gain a better understanding of what's "happening under the hood". Does anybody provide Visual Studio support for *IL in the form of: project templates, IntelliSense integration, and those kind of RAD features? Edits: I don't mean restricted to out of the box support. For example, I can download Visual Studio extensions to support Python, COBOL, etc. Want the same for *IL. There is a stand-alone Intermediate Assembler tool.

  • parsing a string based on specified identifiers

    Let's say that I have the following text: input = "one aaa and bbb two bbbb er ... // three cccc" I would like to parse this into a group of variables that contain criteria = ["one", "two", "three"] v1,v2,v3 = input.split(criteria) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml
