Based on a rough path foundation, we develop model-free approach to stochastic portfolio theory (SPT). Our allows handle significantly more general portfolios compared previous approaches based Föllmer integration. Without the assumption of any underlying probabilistic model, prove pathwise formula for relative wealth process, which reduces in special case functionally generated version so-call...

The current network risk assessment model often ignores the impact of attack cost and intrusion intention on security. In order to better solve problem information security defense strategy selection accurately assess target risk, this paper proposes an path prediction method based game model.The atomic probability is calculated by vulnerability value, benefit. static established combined with ...

Tropical cyclones are intense circular storms that cause significant economic and life losses in the coastal areas of equatorial region. Various statistical models were proposed to forecast tropical cyclone’s potential path. This study has a stacked ensemble-based method increase temporal data’s Cyclone path prediction effectiveness. The can be divided into two phases; first phase, Long Short-T...

In the context of frequent public emergencies, emergency logistics distribution is particularly critical, and because unique advantages unmanned aerial vehicles (UAVs), model coordinated delivery UAVs gradually becoming an essential form distribution. However, omission start-up costs prevents cost UAV battery replacement sorting, assembly verification packages from being factored into total cos...
