AWS Machine Learning Retrain Model

Question

I have some Models created in AWS Machine Learning with a S3 csv file. After a lot of search I didn't find the better way to retrain my model.

I would like to know if there any any option to retrain my models with new data or I if need to create a new one each time.

Answer 1

Amazon ML is providing a set of API (and SDKs) that allows creating programmatically a pipeline that will take new data from S3 and generate the datasource and the ML models from it.

All the components including datasources, ML models, evaluation etc. are immutable, and if you want to retrain, you need to recreate it. It allows you to roll back to a previous model, if the performance of the new model is not better that the old model.
