This paper notes a simple connection between synthetic control and online learning. Specifically, we recognize as an instance of Follow-The-Leader (FTL). Standard results in convex optimization then imply that, even when outcomes are chosen by adversary, predictions counterfactual for the treated unit perform almost well oracle weighted average units' outcomes. Synthetic on differenced data per...

The presented work is part of the project to implement a simulator for determining ship's trajectory in collision situations. aim this article model an optimal ship control system situations taking into account International Regulations Prevention Collisions at Sea. main task was design and realize visualization form simulation. An analysis simulation results also carried out used formulate con...
