[FRIAM] 1. Is the Equal Sign Overrated? Mathematicians Hash It Out | WIRED (Tom Johnson)

[Frank Wimberly]

In the work I did at CMU on statistical causal reasoning, we made heavy use
of equivalence classes.  Our algorithms would find equivalence classes of
causal models (generalizations of acyclic digraphs).  If any edge occurred
in all elements of a class then it represented a cause between the
variables (nodes) associated with the edge.  As I recall.
