What is a common pitfall in model selection?
Model Selection – The process of choosing the most appropriate model for a given dataset and problem.
Overfitting – When a model learns the noise in the training data instead of the actual signal, leading to poor generalization.
Underfitting – When a model is too simple to capture the underlying patterns in the data, resulting in poor performance.
Bias-Variance Tradeoff – The balance between a model's ability to minimize bias (error due to overly simplistic assumptions) and variance (error due to excessive complexity).
