Dimensionality reduction techniques can be helpful for making models work better and faster. However, they come with some challenges:
Loss of Information: When we simplify the data too much, we might lose important details. This can make our models less effective.
Overfitting Risks: If we make the model too simple, it might not understand the important patterns in the data. This is called underfitting.
Computational Costs: Some methods, like PCA, can require a lot of computer power. Plus, they can be hard to understand.
To fix these problems, we can use careful feature selection and regularization techniques. This way, we can find a good balance between how complex our model is and how well we can understand it.
