Info Intervention and its Causal Calculus

The potential outcome framework and structural causal model are two main frameworks for causal modeling, and there are efforts to combine the merits of each framework, such single world intervention graph (SWIG) and its potential outcome calculus. In this paper, we propose the info intervention inspired by understanding as information transfer, and the corresponding causal calculus. On one hand, We explain its connection with do calculus; On the other hand, our info calculus has the same convenience of checking conditional independence as SWIG, and moreover owns a operator σ(·) for formalizing causal queries.
