There are various ensemble methods such as stacking, blending, bagging and boosting.Gradient Boosting, as the name suggests is a boosting method. Extreme Gradient Boosting (xgboost) is similar to gradient boosting framework but more efficient. Voting is an ensemble machine learning algorithm. The least squares parameter estimates are obtained from normal equations. Specially for texts, documents, and sequences that contains many features, autoencoder could help to process data faster and more efficiently. The default Apple Clang compiler does not support OpenMP, so using the default compiler would have disabled multi-threading. Unsupervised learning is a machine learning paradigm for problems where the available data consists of unlabelled examples, meaning that each data point contains features (covariates) only, without an associated label. It's popular for structured predictive modeling problems, such as classification and regression on tabular data, and is often the main algorithm or one of the main algorithms used in winning solutions to machine learning competitions, like those on Kaggle. For regression, a voting ensemble involves making a prediction that is the average of multiple other regression models.
