Answer 1

Overfitting is the term used when an estimated model starts to capture the peculiarities of the data rather than the true relationships between variables.

Overfitting is a mistake that happens when a certain function aligns too closely to a small number of data points in data modeling. Financial experts run the danger of overfitting a model with scant data and getting inaccurate findings.

When a model learns the information and noise in the training data to the point where it adversely affects the model's performance on fresh data, this is known as overfitting. This indicates that the machine learns concepts from the noise or random oscillations in the training data.
