How can we improve the model performance on the test set?

8 Methods to Boost the Accuracy of a Model

1. Add more data. Having more data is always a good idea.
2. Treat missing and Outlier values.
3. Feature Engineering.
4. Feature Selection.
5. Multiple algorithms.
6. Algorithm Tuning.
7. Ensemble methods.

How do you monitor a production model?

Monitoring Your Model The most straightforward way to monitor your ML model is to constantly evaluate your performance on real-world data. You could customize triggers to notify you when there are significant changes in metrics such as accuracy, precision, or F1.

How do you deploy ML models in production?

How to deploy Machine Learning/Deep Learning models to the web

1. Step 1: Installations.
2. Step 2: Creating our Deep Learning Model.
3. Step 3: Creating a REST API using FAST API.
4. Step 4: Adding appropriate files helpful to deployment.
5. Step 5: Deploying on Github.
6. Step 6: Deploying on Heroku.

How can I improve my ML skills?

10 Ways to Improve Your Machine Learning Models

1. Studying learning curves.
2. Using cross-validation correctly.
3. Choosing the right error or score metric.
4. Searching for the best hyper-parameters.
5. Testing multiple models.
6. Averaging models.
7. Stacking models.
8. Applying feature engineering.

How to test a predictive model in production?

Develop Back-Testing and Now-Testing Infrastructure The model will change, as will the software and the data on which predictions are being made. You want to automate the evaluation of the production model with a specified configuration on a large corpus of data.

What to know when running a production test?

When you are running a production test, keep your eye on key user performance metrics so that you know if the test is having any kind of unacceptable impact on the user experience. Be prepared to shut the test down if that’s the case.

Why are so many companies not testing in production?

For this reason, most businesses avoid testing in production altogether because it’s too risky for the end user. But there are problems with not testing in production, too. Test environments are rarely built out to the same level as production environments, so they can never really achieve the scale that you’d see in “real-life.”

Why is testing in production an important competency?

Testing in production is an important core competency for any world-class test team to cultivate. In this post we will give you some practical tips to make testing in production an achievable reality – and to mitigate the obvious risks that it exposes. Sometimes learning a best practice begins by understand a worst practice.
