This often results in better generalization and robustness against overfitting. 61. How would you deal with concept drift in a real-time data streaming application? Concept drift can be handled by continuously monitoring model performance, setting up alerting mechanisms for performance degradation, and ...
Machine Learning - (Overfitting|Overtraining|Robust|Generalization) (Underfitting) A learning algorithm is said to overfit if it is: more accurate in fitting known data (ie training data) (hindsight) but less accurate in predicting new data (ie test data) (foresight) Ie the model... Machine...
