How often should I refresh a machine learning project?
This relies on a number of variables, such as industry trends.
Every six months, you might wish to update the data if your industry is one that changes quickly.
If it changes more slowly, you might wish to refresh the data every one to three years.
Additionally, you might wish to update the data more regularly if there is a significant market change, like the entry of a new player or the release of a game-changing new product.
