Web1 day ago · Avoiding overfitting in panel data and explainable ai. I have panel data consisting of yearly credit ratings as a target variable and some features for its estimation. Each year of my 20 year time series i have around 400 firms. I use shap to analyse some of those features and analyse how this results change over time. WebOverfitting is the main problem that occurs in supervised learning. Example: The concept of the overfitting can be understood by the below graph of the linear regression output: As we can see from the above graph, the model tries to cover all the data points present in the scatter plot. It may look efficient, but in reality, it is not so.
