How do you evaluate a predictive model?

How do you evaluate a predictive model?

To evaluate how good your regression model is, you can use the following metrics:

1. R-squared: indicate how many variables compared to the total variables the model predicted.
2. Average error: the numerical difference between the predicted value and the actual value.

How do you evaluate a model in production?

What you should consider more often in production scenario is revenue for your model , and A/B test is a must . As in your case , you can exactly measure how much money can your model for loan default prediction bring to you , or how much loss can your model can save for you .

How do you ensure that the model you build is also functional in production?

Below a five best practice steps that you can take when deploying your predictive model into production.

1. Specify Performance Requirements.
2. Separate Prediction Algorithm From Model Coefficients.
3. Develop Automated Tests For Your Model.
4. Develop Back-Testing and Now-Testing Infrastructure.
5. Challenge Then Trial Model Updates.

How do you deploy the machine learning model in production?

How do you deploy a time series model in production?

Production deployment of time series forecasting

1. Building a data pipeline. Establishing a data pipeline is the first step to getting the right data.
2. Generating forecasts in the future and on demand.
3. Evaluating and refining models.
4. Communicating uncertainty.
5. Scaling up and out.

How do you deploy a ML model in production?

What’s the purpose of the deployment of predictive models?

Predictive Model Deployment : Predictive Model Deployment provides the option to deploy the analytical results in to every day decision making process, for automating the decision making process. The predictive models validation and deployment are time consuming activities,…

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 are the components of the predictive analytics process?

For more information of predictive analytics process, please review the overview of each components in the predictive analytics process: data collection (data mining), data analysis, statistical analysis, predictive modeling and predictive model deployment. What is Predictive Model Deployment?

How are predictive performance models evaluation metrics important?

Instead, we might want to use a metric that evaluates only the true positives and the false negatives, and determines how good the model is at prediction of the case of the disease. Proper predictive performance models evaluation is also important because we want our model to have the same predictive evaluation across many different data sets.
