Identifiability assumptions
Webgraph identifiability result in the two-variable set-ting under relaxed assumptions. We then show the first identifiability result using the entropic ap-proach for learning causal graphs with more than two nodes. Our approach utilizes the property that ancestrality between a source node and its descendants can be determined using the bivari- Web24 mrt. 2024 · Under these assumptions, we demonstrate that there is an excitation and measurement pattern that results in more accurate estimates than others. ...
