Ancestral polytree
Causal polytrees are singly connected causal models and they are
frequently applied in practice. However, in various applications, many
variables remain unobserved and causal polytrees cannot be applied
without explicitly including unobserved variables. Our study thus
proposes the ancestral polytree model, a novel combination of
ancestral graphs and singly connected graphs. Ancestral graphs can
model causal and non-causal dependencies, while singly connected
models allow for efficient learning and inference. We discuss the
basic properties of ancestral polytrees and propose an efficient
structure learning algorithm. Experiments on synthetic datasets and
biological datasets show that our algorithm is efficient and the
applications of ancestral polytrees are promising.
