The characteristics of artificial intelligence are introduced, and the advantages of integrating artificial intelligence with the financial industry are analysed in depth, in conjunction with intelligent marketing and intelligent risk control. An Internet finance system is designed and a risk control model based on a logistic regression algorithm is established. Finally, the model is tested against the actual situation and the index scores are adjusted to produce a score with expert experience.
