WebJul 25, 2024 · Graph-Based Decoders. It is necessary to deal with graph theory to understand these algorithms. A graph G=(V, A) is a set of vertices V (called also nodes), that represent the tokens, and arcs (i, j)∈ A where i, j ∈ V. The arcs represent the dependencies between two words. In a Graph-based dependency parser, graphs are … WebIn a static toolkit, you define a computation graph once, compile it, and then stream instances to it. In a dynamic toolkit, you define a computation graph for each instance. It …
