First, we divide the dataset X into K parts as X1; X2; ... ; XK. Then for each fold i, we use Xi as the validation set and the remaining as the training set. Possible values of K are 10 or 30. One extreme case of K-fold cross-validation is leave-one-out, where K = N and each validation set has only one instance. If we have more computation power, we can have multiple runs of K-fold cross-validation, such as 10 x 10 cross-validation or 5 x 2 cross-validation. Bootstrapping ------------- [](#bootstrapping) If we have very small datasets, we do not insist on the non-overlap of training and validation sets. In bootstrapping, we generate K multiple training sets, where each training set contains N examples (like the original dataset). To get N examples, we draw examples with replacement. For the validation set, we use the original dataset. The drawback of bootstrapping is that the bootstrap samples overlap more than the cross-validation sample, hence they are more dependent. Video Lectures ============== [](#video-lectures) [![](https://github.com/StarlangSoftware/Sampling/raw/master/video.jpg)](https://youtu.be/wijWOiv70nE) For Developers ============== [](#for-developers) You can also see [Java](https://github.com/starlangsoftware/Sampling), [Python](https://github.com/starlangsoftware/Sampling-Py), [Cython](https://github.com/starlangsoftware/Sampling-Cy), [Js](https://github.com/starlangsoftware/Sampling-Js), [C#](https://github.com/starlangsoftware/Sampling-CS), [Swift](https://github.com/starlangsoftware/Sampling-Swift), or [C++](https://github.com/starlangsoftware/Sampling-CPP) repository. Requirements ------------ [](#requirements) - [Php 8.4 or higher](#php) - [Git](#git) ### Php [](#php) To check if you have a compatible version of Php installed, use the following command: ``` php -V ``` You can find the latest version of Php [here](https://www.php.net/downloads/). ### Git [](#git) Install the [latest version of Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git). Download Code ------------- [](#download-code) In order to work on code, create a fork from GitHub page. Use Git for cloning the code to your local or below line for Ubuntu: ``` git clone ``` A directory called Sampling will be created. Or you can use below link for exploring the code: ``` git clone https://github.com/starlangsoftware/Sampling-Php.git ``` Open project with PhpStorm IDE ------------------------------ [](#open-project-with-phpstorm-ide) Steps for opening the cloned project: - Start IDE - Select **File | Open** from main menu - Choose `Sampling-Php` file - Select open as project option - Couple of seconds, dependencies will be downloaded. For Contibutors =============== [](#for-contibutors) ### composer.json file [](#composerjson-file) 1. autoload is important when this package will be imported. ``` "autoload": { "psr-4": { "olcaytaner\\WordNet\\": "src/" } }, ``` 2. Dependencies should be maximum (not only direct but also indirect references should also be given), everything directly in the code should be given here. ``` "require-dev": { "phpunit/phpunit": "11.4.0", "olcaytaner/dictionary": "1.0.0", "olcaytaner/xmlparser": "1.0.1", "olcaytaner/morphologicalanalysis": "1.0.0" } ``` ### Data files [](#data-files) 1. Add data files to the project folder. Subprojects should include all data files of the parent projects. ### Php files [](#php-files) 1. Do not forget to comment each function. ``` /** * Returns true if specified semantic relation type presents in the relations list. * * @param SemanticRelationType $relationType element whose presence in the list is to be tested * @return bool true if specified semantic relation type presents in the relations list */ public function containsRelationType(SemanticRelationType $relationType): bool{ foreach ($this->relations as $relation){ if ($relation instanceof SematicRelation && $relation->getRelationType() == $relationType){ return true; } } return false; } ``` 2. Function names should follow caml case. ``` public function getRelation(int $index): Relation{ ``` 3. Write getter and setter methods. ``` public function getOrigin(): ?string public function setName(string $name): void ``` 4. Use standard javascript test style by extending the TestCase class. Use setup when necessary. ``` class WordNetTest extends TestCase { private WordNet $turkish; protected function setUp(): void { ini_set('memory_limit', '450M'); $this->turkish = new WordNet(); } public function testSize() { $this->assertEquals(78327, $this->turkish->size()); } ``` 5. Enumerated types should be declared with enum. ``` enum CategoryType { case MATHEMATICS; case SPORT; case MUSIC; case SLANG; case BOTANIC; ``` 6. If there are multiple constructors for a class, define them as constructor1, constructor2, ..., then from the original constructor call these methods. ``` public function constructor1(string $path, string $fileName): void public function constructor2(string $path, string $extension, int $index): void public function __construct(string $path, string $extension, ?int $index = null) ``` 7. Use \_\_toString method if necessary to create strings from objects. ``` public function __toString(): string ``` 8. Use xmlparser package for parsing xml files. ``` $doc = new XmlDocument("../test.xml"); $doc->parse(); $root = $doc->getFirstChild(); $firstChild = $root->getFirstChild(); ``` ### Health Score 31 — LowBetter than 66% of packages Maintenance70 Regular maintenance activity Popularity4 Limited adoption so far Community8 Small or concentrated contributor base Maturity38 Early-stage or recently created project Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
