courses.ics.hawaii.educomposite of R and S is the relation consisting of ordered pairs (a;c), where a 2A;c 2C, and for which there exists an element b 2B such that (a;b) 2R and (b;c) 2S. We denote the composite of R and S by S R. Powers of a Relation Let R be a relation on the set A. The powers Rn;n = 1;2;3;:::, are defined recursively by R1 = R and Rn+1 = Rn R. 9 ...

Since our pre-trained model was trained on contiguous sequences of text, we require some modifications to apply it to these tasks. Previous work proposed learning task specific architectures on top of transferred representations [44].

people.cs.pitt.edu• Ordered-n tuples are used to represent an ordered collection. Definition: An ordered n-tuple (x1, x2, ..., xN) is the ordered collection that has x1 as its first element, x2 as its second element, ..., and xN as its N-th element, N 2. Example: • Coordinates of a point in the 2-D plane (12, 16) x y
