WebSep 20, 2024 · CYK is a parsing algorithm for context-free grammar. It is based on bottom-up dynamic programming. The CYK table is initialized by the number of connected components and their associated classifier probability (Table 2). Once the CYK parsing table is initialized, the algorithm builds new hypotheses of increasing size. WebWhile the method fills the diagonals of “table”, it fills in “table2” with the corresponding probabilities. On lines 113-143 in the code, weighted CYK is implemented.
