Constructing Final Coalgebras with Modal Logic

Using modal logic, we can construct final coalgebras for some well known functors in the coalgebraic theory of automata without mention of the final sequence typically used in a such constructions. This logical description of the final coalgebra lends itself to applications in machine learning, such as reconstructing automata from partial data about their behaviour.
