A method of generating an assistant feature is provided. A plurality of main features is provided. A first main feature is selected from the main features. A plurality of rule-based features is disposed around the first main feature. A model-based feature is generated around the first main feature. An overlap Boolean feature is extracted from the rule-based features, wherein the overlap Boolean feature overlaps with the model-based feature in an overlap ratio up to a target value. The overlap Boolean feature serves as an assistant feature, and the assistant feature and the first main feature constitute a transfer feature. |
