This means that the neural network algorithm at this time has chosen a clear direction of travel, not like the beginning of the output of a faint light gray area, but the output of a white section.Stanford University public Class machine learning: Neural Net
Singleton mode is only instantiated once, which means that it is not possible to use the New keyword when instantiating, and here is the use of the example, you can refer to the use of the bar The following is a single example pattern code: The code is as follows: ; getinstance () nbsp;* then it should be written as a call nbsp;* $object = Easyframework_easy_mysql::getinstance () nbsp;* if the getinstance

*/
$conn = new Dbconn ();
$conn->connect ();
$conn = new Dbconn ();
$conn->connect ();
You cannot direct the new object after using the single case mode, you must call getinstance to get
$conn = Dbcon
