The invention relates to the technical field of car rental recommendation, in particular to a car rental recommendation method and
system based on
artificial intelligence, and aims to overcome the limitation of traditional rule recommendation on context understanding by fusing user historical car use records and current input requirements, constructing a multi-dimensional
state vector and accurately representing user behavior habits and travel scenes. A
reinforcement learning model is adopted to model a car
renting behavior strategy based on a Markov
decision process, a
reward value is calculated in combination with real feedback such as clicking,
renting conversion and scoring, a recommendation strategy is dynamically optimized through a strategy gradient
algorithm, output recommendation actions cover
vehicle type categories, price ranges and place screening, personalized matching of cars is achieved, and the car
renting efficiency is improved. Recommendation generalization is avoided, and recommendation accuracy and
user satisfaction are improved. The model has continuous learning ability, adapts to changes of different car renting scenes, and improves the intelligent level and practical value of the recommendation
system.
