A mapping (T Arightarrow B) is a relation from A to B which is both functional and left-total.
R is known as functional, if xRy, xRz implies that y = z, for x ∈ A and y, z ∈ B. A mapping T : A → B is a relation from A to B which is both functional and left-total.
We present a new algorithm for learning hypernym (is-a) relations from text, a key problem in machine learning for natural language understanding.
If something is in something else in virtue of the whole composite and from inside, then it is a relation; if from outside, it is a possession (habitus); if partially from inside and partially from outside, it is a position (In Cat., cap. de numero et sufficientia praedicamentorum, pp. 252 53).
The latter issue was taken up in Weyl's "Habilitation" lecture (1910), where he addressed the general question: when is a relation explicitly definable from a set of given primitive concepts in mathematics?
From the illustration of the UE positions as shown in Figure 6, it can be observed that there is a relation between distance from the eNB and the relative throughput error.
Duncan is a relation of two brothers from Beauly, another shinty community greatly affected by WWI.
Furthermore, "roughly equal" is a relation that can be defined only in virtue of three items, and as such, appears to be something distinct from a standard comparative relation.
She sees nothing of her family, and at her sister-in-law's wedding she has an enigmatic conversation with a middle-aged man who's clearly a relation from whom she's estranged.
We show: (A) that R is a functional relation from the objects of P−a to the objects of Q−b, and then (B) that R is a one-to-one functional relation from the objects of P−a onto the objects of Q−b.
