What is an ensemble method in NLP? |
|
Answer» An ENSEMBLE approach is a methodology that DERIVES an output or makes predictions by combining numerous independent similar or distinct models/weak learners. An ensemble can also be CREATED by combining various models such as random forest, SVM, and logistic regression. Bias, variance, and NOISE, as we all know, have a negative impact on the mistakes and predictions of any machine learning model. Ensemble approaches are employed to overcome these DRAWBACKS. |
