I have trained a Linear SVC model using Flink ML library. I wish to extract the SVM hyperplane so I can use the rules in Pattern Matching API of Flink CEP. This is possible when using the sklearn library in python but is there a way to extract the classifier rules in flink-ml?
Can I extract the Linear SVC model coefficient and intercept in Apache Flink ML?

Yes you can extract the hyperplane parameter from the model data fitted by a LinearSVC Estimator. Here are the example code snippets to get model data using Python API [1] and Java API [2] respectively. Hope it helps!
