livefootballscoreLet’s suppose you have a number of machine learning models running in your production environment. Perhaps you are using best free online slots with bonuses MLOps to help you with this effort. Perhaps you are doing it using your own custom-built method. Let’s also suppose that you are monitoring those models using metrics that help you understand their service health, accuracy, and so on. 

winning online poker tournamentsFirst of all, congratulations. You are among the elite 10% of organizations that have actually managed to get this far. The other 90% are still trying to figure out how to get their first model into production and haven’t even started to think about how to monitor them.

1. Replace the deteriorating model with a new one
2. Retrain the deteriorating model
3. Rollback to an earlier version of the model

hot sexi indianRegardless of which option you choose, the risk of simply replacing a model that is currently running in production with another model or version is simply bad practice. 

best free online slots with bonuses,So, Why Is This?

best free online slots with bonuses,What Is the Best Way to Address Model Deterioration?

history of handball in ugandaThere are several ways to conduct these important model management activities correctly. Most of them can be characterized as “champion/challenger” best practices.

nike green basketball vestChampion/challenger is a method that allows different approaches to testing predictive models in a production environment. It’s a similar concept to A/B testing from a marketing perspective. The champion/challenger technique enables you to both monitor and measure predictions using different variations of the same decision logic. The overall goal is to identify which variation is the most successful.

The challengers will compete against each other for a chance to become the new champion. The results of this production-based competition can then be reviewed, and the MLOps engineer can make a recommendation as to which of the models is the winner (i.e., the existing champion or one of the challengers).

This means that the activity takes place (or should be taking place) practically all the time, across all production models that are running. This enables a “hot-swap” of models to be undertaken at any given moment, as opposed to waiting for an answer or for testing to complete.

handheld soccer rebounderIn our latest 6.1 release of best free online slots with bonuses , we have added a champion/challenger framework to our MLOps product. This new capability enables best free online slots with bonuses customers, within a governed framework, to run their challenger models in shadow mode, alongside their current best performing model.

You can select a best free online slots with bonuses model or a custom model as a champion, then pick up to three challenger models (which can also be automatically generated by best free online slots with bonuses AutoML, or built externally from best free online slots with bonuses ) to shadow it.

One hundred percent of prediction requests are serviced by the current champion model. Later on, the same prediction requests are replayed against the challengers for analytical purposes.

A/B testing lets you gradually test out a new model and it lets you get better experimental results on the impact to your KPIs of the different models. However, the major drawback of this approach for many organizations is that applications are randomly getting predictions from different models.

With A/B testing, you cannot compare a maximum accuracy insurance pricing model because you are often prohibited from putting that challenger model into a production environment. And you might not want to run a baseline reference model live because you would leave a lot of accuracy on the table.

You can then further analyze predictions, accuracy, and data errors over time and zoom in on any period in the past.

Users can also improve the stability of the model replacement process by running proposed replacements in a “shadow mode” before promoting them.

This enables you to react to constantly changing business conditions in order to maintain the highest possible model quality over time.
