Understanding Underfitting and Overfitting in Machine Learning
Machine learning models are built to find patterns in data and make predictions. However, a model can become either too simple or too complex. These two common problems are known as underfitting and overfitting. A useful lesson on this topic is available in Kaggle’s Intro to Machine Learning course by Dan Becker: Kaggle Lesson:https://www.kaggle.com/code/dansbecker/underfitting-and-overfitting What…
