MLPACK

MLPACK provides a simple timer interface for the timing of machine learning methods. The results of any timers used during the program are displayed at output by the mlpack::CLI object, when --verbose is given:
$ allknn -i=data.csv -k 5 <...> [INFO ] Program timers: [INFO ] computing_neighbors: 0.044764s [INFO ] total_time: 0.061249s [INFO ] tree_building: 0.003075s
The mlpack::Timer class provides three simple methods:
void Timer::Start(const char* name); void Timer::Stop(const char* name); timeval Timer::Get(const char* name);
Each timer is given a name, and is referenced by that name.
A "total_time" timer is run by default for each MLPACK program.
Below is a very simple example of timer usage in code.
#include <mlpack/core.hpp> using namespace mlpack; int main(int argc, char** argv) { CLI::ParseCommandLine(argc, argv); // Start a timer. Timer::Start("some_timer"); // Do some things. DoSomeStuff(); // Stop the timer. Timer::Stop("some_timer"); }
If the --verbose flag was given to this executable, the resultant time that "some_timer" ran for would be shown.
