The Maintenance of Neural Network Models

Deep learning neural network models used for predictive modeling may need to be updated.

This may be because the data has changed since the model was developed and deployed, or it may be the case that additional labeled data has been made available since the model was developed and it is expected that the additional data will improve the performance of the model.

It is important to experiment and evaluate with a range of different approaches when updating neural network models for new data, especially if model updating will be automated, such as on a periodic schedule.

There are many ways to update neural network models, although the two main approaches involve either using the existing model as a starting point and retraining it, or leaving the existing model unchanged and combining the predictions from the existing model with a new model.
