Consider you want to predict the correct answer for XOR popular problem. You Knew what is XOR(e.g [x0 x1] => y). for example [0 0] => 0, [0 1] => [1] and... #Load Sickit learn data from sklearn.neighbors import KNeighborsClassifier #X is feature vectors, and y is correct label(To train...

This example shows more detailed build settings: env=Environment( CPPPATH='/usr/include/boost/', CPPDEFINES=['foo'], LIBS=['bar'], SCONS_CXX_STANDARD='c++11') env.Program('hello', Glob('src/*.cpp')) This builds the executable hello from all the cpp files in src, with the f...

The Binary Search Tree (BST) is a hierarchical data structure with a single pointer to the root node. The Node in the BST generally contains "items" (such as numbers or names) for fast look up. Each node has at-most two children (left and right). Every node is organized by some key data f...

To match a query string, a condition must be added to the RewriteRule. This is done by putting RewriteCond directives before the corresponding rule. In the following example we dynamically internally rewrite an old url to a new url. RewriteCond %{QUERY_STRING} ^name=([^&]*)$ RewriteRule ^oldsc...

Traversing from the root node to a descendant element using the child axis: /child::html/child::body/child::div/child::span Since the child axis is the default axis, this can be abbreviated to: /html/body/div/span

The descendant and descendant-or-self axes can be used to find all descendant elements of a node at any depth. In contrast, the child axis only traverses immediate children. /child::html/descendant::span /child::html/descendant-or-self::* The double slash // is a shortcut for /descendant-or-sel...

The parent axis contains only the parent of a node. The following expression selects the html element by taking a detour over the body element: /child::html/child::body/parent::html .. is a shortcut for parent::node() The ancestor and ancestor-or-self axes traverse all ancestors of a node. The ...

The following-sibling and preceding-sibling axes contain the siblings before or after the context node, and the following and preceding axes contain all nodes in the document before or after the context node, but: None of these axes contain attribute or namespace nodes. The following axis doesn'...
