题目：Optimal Insurance Strategies: A Hybrid Deep Learning Markov Chain Approximation Approach
主办单位：betway体育
内容介绍：This paper studies deep learning approaches to find optimal reinsurance and dividend strategies for insurance companies. Due to the randomness of the financial ruin time
to terminate the control processes, a Markov chain approximation-based iterative deep learning algorithm is developed to study this type of infinite-horizon optimal control problems. The optimal controls are approximated as deep neural networks in both cases of regular and singular types of dividend strategies. The framework of Markov chain approximation plays a key role in building the iterative equations and initialization of the algorithm. We implement this self-learning approach to approximate the optimal strategies and compare the learning results with existing analytical solutions.
Satisfactory computation efficiency and accuracy are achieved as presented in numerical examples.
