1. Transition Mechanisms (60 points) (a) (10 pts) Given a sentence "I parsed this sentence correctly" with the transitions, complete the following table. The first three steps are provided in the table, showing the configuration of the stack and buffer, as well as the transition and the new dependency (if has) for the following steps. ROOT parsed this sentence correctly Stack Buffer New dependency Transition [ROOT] [I, parsed, this, sentence, correctly] Initial Configuration [ROOT, I] [parsed, this, sentence, correctly] SHIFT [ROOT, I, parsed] [this, sentence, correctly] SHIFT [ROOT, parsed] [this, sentence, correctly] parsed I LEFT-ARC (b) (10 pts) A sentence containing n words will be parsed in how many steps (in terms of n)? Briefly explain in 1-2 sentences why. (c) (20 pts) Implement the transition mechanisms, SHIFT, LEFT-ARC, and RIGHT-ARC. (d) (20 pts) Implement Minibatch Dependency Parsing based on the following algorithm. Algorithm Minibatch Dependency Parsing Input: sentences, a list of sentences to be parsed and model, our model that makes parse decisions

Can you give the 6th one? And the 5th one? The question is also given to answer the 6th part b. 5. Let (Î»,z) be an approximate eigenpair of A âˆˆ â„â¿Ë£â¿, where |z|Â² = 1. Assume that A is diagonalizable, A = XÎ›Xâ»Â¹. Show that there exists an eigenvalue Î» of A such that |Î» - Î»Ì‚| â‰¤ Îº(X)â‹…|r|Â², where Îº(X) = |Î»|Â²â‹…|Î»â»Â¹|Â² is the condition number of X, and r is the residual vector: r = Az - z. 6.
