What to do after getting predicted Yfit from regression learner?

I have trained a model with regression learner and got the Yfit=TrainedModel.predictFcn(data) equation and was able to get the predicted value. What's the next step and how do I use it for predictive maintainence? Machine learning has been extremely confusing especially with little to no useful tutorials. Please help

You have the TrainedModel with you.....if you feel the accuracy is satisfactory, validate it. If the validation (for unseen data, while training) is good enough then your model is ready and you can use it/ deploy it for prediction new data.
