Which algorithm takes the crown: Light GBM vs XGBOOST?

If you are an active member of the Machine Learning community, you must be aware of Boosting Machines and their capabilities. The development of Boosting Machines started from ADABOOST to today's favourite XGBOOST. XGBOOST has become a de-facto algorithm for winning competitions at Analytics Vidhya and Kaggle, simply because it is extremely powerful. But given lots and lots of data, even XGBOOST takes a long time to train. Many of you might not be familiar with the Light Gradient Boosting, but you will be after reading this article. The most natural question that will come to your mind is – Why another boosting machine algorithm?
