What supervised/unsupervised models are used for predictive analytics? Do we need a data scientiest to create model or will the predictive analytics solution have build in libraries and based on the clustering and deploy the models automatically? How can we determine the fit of the model and which model was used for the data set?
I have seen some products in which the system creates multiple models for each line of the dataset automatically without the need for data scientist. Is SAP predictive analytics solution on similar lines?
