FLAML is an open-source automated python machine learning library that leverages the structure of the search space in search tree algorithmic problems and is designed to perform efficiently and robustly without relying on meta-learning, unlike traditional Machine Learning algorithms. To choose a search order optimized for both cost and error and it iteratively decides the learner, hyperparameter, sample size and resampling strategy while leveraging their compound impact on both cost and error of the model as the search proceeds.

Between October and December 2016, Kaggle organised a competition with over 3,000 participants, competing to predict the loss value associated with American insurance company Allstate. In 2017, Google scholar Alexy Noskov won second position in the competition. In a blog post on Kaggle, Noskov walked readers through his work. The primary models he employed were…

When asked about his approach to data science problems, Sergey Yurgenson, the Director of data science at DataRobot, said he would begin by creating a benchmark model using Random Forests or XGBoost with minimal feature engineering. A neurobiologist (Harvard) by training, Sergey and his peers on Kaggle have used XGBoost(extreme gradient boosting), a gradient boosting…

In recent times, ensemble techniques have become popular among data scientists and enthusiasts. Until now Random Forest and Gradient Boosting algorithms were winning the data science competitions and hackathons, over the period of the last few years XGBoost has been performing better than other algorithms on problems involving structured data. Apart from its performance, XGBoost is also recognized for its speed, accuracy and scale. XGBoost is developed on the framework of Gradient Boosting.
