Machine Learning: Random Forest with Python from Scratch - Overfitting and Underfitting

The video tutorial explains the concepts of overfitting and underfitting in model training. Overfitting occurs when a model performs well on training data but poorly on testing data due to excessive flexibility. Underfitting happens when a model is too rigid, failing to perform well on both training and testing data. The solution is to find a balance between flexibility and rigidity, depending on the data. The tutorial emphasizes understanding these concepts theoretically before implementing them programmatically in Python.
