摘要： A dialog generation method, apparatus, and electronic device are disclosed in this application. The method includes training a sequence to sequence (seq2seq)-based dialog model using a loss function including topic range constraint information; and generating a dialog using the trained dialog model. With embodiments of this application, topic range constraint information is introduced in the process of dialog model training using a loss function including the topic range constraint information, thus helping to prevent the trained model from producing low-quality meaningless replies.

摘要： Implementations of the present specification disclose a graphical structure model-based method, apparatus, and device for credit risk control. The solution includes: establishing an appropriate enterprise relationship network in advance based on data related to an enterprise and factors associated with the enterprise; performing feature integration and defining a graphical structure model; training the graphical structure model by using a labeled sample; calculating embedding vectors of a node after a plurality of iterations in hidden feature space and a predicted probability of the node by using the trained graphical structure model; and performing credit risk control on the node based on the embedded factor and the predicted probability.
