无家可归的青年由于从事高风险行为而容易感染艾滋病毒。许多机构采取干预措施，教育/培训一批选定的无家可归青年了解预防艾滋病毒的做法，并依靠通过其社会网络口口相传传播信息。以前的工作在战略选择的干预参与者不处理的社会网络的结构和不断发展的网络状态的不确定性，可能会造成重大的缺陷，在传播信息。因此，我们开发了PSINET，一个决策支持系统，以帮助机构完成这项任务。PSINET包括以下关键的新颖性：（一）它处理网络结构和不断变化的网络状态的不确定性;（二）它解决了这些不确定性，通过使用POMDPs的影响最大化;（三）它提供了算法的进步，使高质量的近似解决方案，这样的POMDPs。PSINET是与My Friend's Place（一个为洛杉矶无家可归的年轻人提供服务的机构）合作开发的，目前正在由他们的官员进行审查。
Homeless youth are prone to HIV due to their engagement in high risk behavior. Many agencies conduct interventions to educate/train a select group of homeless youth about HIV prevention practices and rely on word-of-mouth spread of information through their social network. Previous work in strategic selection of intervention participants does not handle uncertainties in the social network’s structure and in the evolving network state, potentially causing significant shortcomings in spread of information. Thus, we developed PSINET, a decision support system to aid the agencies in this task. PSINET includes the following key novelties: (i) it handles uncertainties in network structure and evolving network state; (ii) it addresses these uncertainties by using POMDPs in influence maximization; (iii) it provides algorithmic advances to allow high quality approximate solutions for such POMDPs. Simulations show that PSINET achieves ∼60% more information spread over the current state-of-the-art. PSINET was developed in collaboration with My Friend’s Place (a drop-in agency serving homeless youth in Los Angeles) and is currently being reviewed by their officials.
