Task: Question Answering
Input (English): Since pre-trained models operate on subword level, we need to estimate subword translation probabilities. For the purpose of evaluating the contextual representations learned by our model, we do not use part-of-speech tags. Contextualized representations are directly fed into Deep-Biaffine layers to predict arc and label scores. Table TABREF34 presents the Labeled Attachment Scores (LAS) for zero-shot dependency parsing. 
 Question: What metrics are used for evaluation?
Output (English): translation probabilities Labeled Attachment Scores (LAS)
