Question - How Regularly Must an Algorithm be Updated?
Answer -
It completely depends on the accuracy and precision being required at the point of delivery and also on how much new data we have to train on. For a model trained on 10 million rows its important to have new data with the same volume or close to the same volume. Training on 1 million new data points every alternate week, or fortnight won’t add much value in terms of increasing the efficiency of the model.
