Preface In the recent game used xgboost this game artifact, because in the MATLAB has a large number of existing functions, and switching dual systems too troublesome, inherited want to install Xgboost on the win10 to simplify the operation. Preparation Process Viewed two blogs prior to installation (1) [anaconda2 install Xgboost under WIN10] (2) 64-bit WIN10 in

Preface--Remember when Ali internship, we are using mllib under the GBDT to train model. However, since mllib is not open source, it is not available outside the company. Later to participate in the Kaggle competition, recognized a GDBT useful tools, xgboost, so seriously study a bit.

Https://github.com/beniz/deepdetectDeepdetect (http://www.deepdetect.com/) is a machine learning APIs and server written in C++11. It makes state of the "Art machine" learning easy-to-work with and integrate into existing applications.Deepdetect relies on external machine learning libraries through a very generic and flexible API. At the moment it had support for the Deep Learning Library Caffe and distributed gradient boosting library xgboost.Deepdetect Machine learning Caffe and

At the beginning of 2017, Microsoft Open source New machine learning Framework LIGHTGBM, based on GBDT, it is said that the Higgs dataset LIGHTGBM nearly 10 times times faster than Xgboost, the memory occupancy rate is about 1/6 of XgboostEnglish Document: http://lightgbm.apachecn.org/cn/latest/index.html Xgboost is the best boosting model of the past, since rumors of LIGHTGBM performance is higher, then w

This blog content is in the last blog scikit feature selection, Xgboost regression prediction, model optimization on the basis of the actual combat optimization, so before reading this blog, please go to see the previous article. The work I did earlier was basically about feature selection, and I wanted to write about some of the little experiences with xgboost parameter adjustments. I have also seen a lot

Xgboost is the most sought-after machine learning algorithm in recent years, proposed by Chen Tianchi of the University of Washington. Recently Learning machine learning, so need to install this tool. However, there are many tutorials on the Internet to install Xgboost, some of them are too complicated to install additional software, some look simple but they follow the steps to install it again, the test i

Use Cases Code Modification As mentioned above, TensorFlow is a rapidly evolving learning framework that requires a lot of dependencies in tensorflow execution, such as numpy,scipy,scikit-image,matplotlib and NLTK, etc. , and the updates to these dependent packages themselves are developing at a different pace, with inconsistent schedules. This also directly leads to, in the process of using TensorFlow, will continue to meet because the version is not supported, or
