The invention provides an abnormal bidding recognition model training method and device, and an abnormal bidding recognition method and device, which can be used in the field of artificial intelligence or finance, and the abnormal bidding recognition model training method comprises the following steps: extracting a bidding subject associated information set from historical bidding data; expanding the bidding subject associated information set to obtain a candidate abnormal bidding feature set; determining an abnormal bidding feature from the candidate abnormal bidding features based on the correlation between the candidate abnormal bidding features in the candidate abnormal bidding feature set and the abnormal bidding; and training the abnormal bidding identification model based on the abnormal bidding features. 本公开提供了一种异常投标识别模型训练方法、异常投标识别方法及装置，可用于人工智能领域或者金融领域，该训练异常投标识别模型的方法包括：从历史投标数据中提取投标主体关联信息集合；对投标主体关联信息集合进行扩展，得到候选异常投标特征集合；基于候选异常投标特征集合中候选异常投标特征与异常投标之间的相关性，从候选异常投标特征中确定异常投标特征；以及基于异常投标特征对异常投标识别模型进行训练。
