Strict Integer as Categorical vs Heuristic Inference in OpenCV TrainData: Which Ensures Consistent Feature Types?

Goal Determine the most reliable approach for determining variable types in cv::ml::TrainData when a feature column contains a mixture of integer and floating‑point values. Constraint OpenCV’s current inference heuristic may classify a mixed column as continuous, potentially misrepresenting categorical data. The library documentation does not specify how suc
