Gradient Boosting for classification. The Gradient Boosting Classifier is an additive ensemble of a base model whose error is corrected in successive iterations (or stages) by the addition of Regression Trees which correct the residuals (the error of the previous stage). Import: from sklearn.ensem...
This is a basic example of a C Extension using C++ and Boost. C++ Code C++ code put in hello.cpp: #include <boost/python/module.hpp> #include <boost/python/list.hpp> #include <boost/python/class.hpp> #include <boost/python/def.hpp> // Return a hello world string. st...
A query can be boosted to increase it's score relative to other subqueries. This is done by wrapping it with a BoostQuery Query lessRelevantQuery = new TermQuery(new Term("fieldname", "ipsum")); //Five times as interesting Query highlyRelevantQuery = new BoostQuery( ...
Component definition ko.components.register('progress-bar', { viewModel: function(params) { var that = this; // progress is a numeric value between 0 and 100 that.progress = params.progress; that.progressPercentual = ko.computed...

Things are easy when you have to use a C++ library in a Python project. Just you can use Boost. First of all here is a list of components you need: A CMakeList.txt file, because you're going to use CMake. The C++ files of the C++ project. The python file - this is your python project. Let's...
#include <iostream> #include <vector> #include <string> #include <boost/algorithm/string.hpp> using namespace std; int main() { // String to split string str = "You're supposed to see this!|NOT THIS!!!!!!"; // Line container vec...
If a function returns a std::vector type, and it is exposed to Python directly like std::vector<float> secondMethod() { return std::vector<float>(); } BOOST_PYTHON_MODULE(CppProject) { boost::python::def("getEmptyVec", secondMethod); } then when the functions...
(Beginner level; IDE: CLion) First, install boost from the Cygwin mirror: open the install exe, search for boost, install the packages. After boost is installed: it will be located in /usr/include/boost. This is where everything is. All #include statements will be a path from the boost folder,...
There is a bug/fix for boost 1.64, the bug only affects Windows, apparently. reference: https://github.com/klemens-morgenstern/boost-process/issues/90 and https://github.com/klemens-morgenstern/boost-process/commit/74814e46c1614850a8e447fd689c21cf82f36ceb in file boost\process\detail\windows\a...
