  1. How does Dense Passage Retrieval decide which passages match a query?
    • Kuenzanisa dense vector inomiririra yemibvunzo uye ndima nekufanana
    • Kuverenga kuti mangani mazwi emibvunzo anobuda mugwaro rega rega
    • Kushandura mubvunzo muSQL usati watsvaga
    • Rongedza magwaro zvichienderana nekuburitswa kwaakaitwa nguva pfupi yadarika
  2. DPR inoshandisa 'bi-encoder' dhizaini. Zvinorevei izvo?
    • Inonyora zvinyorwa kaviri uye inoita mavhareji emigumisiro
    • Inoshanda chete pamagwaro emitauro miviri
    • Inoisa kodhi mavara uye mazwi panguva imwe chete
    • Inoshandisa encoder maviri akaparadzana, imwe yemibvunzo uye imwe yendima
  3. Sei mavheji anogona kuverengerwa pachine nguva muDPR?
    • Nekuti ndima hadzimbochinji kana dzangonyorwa
    • Nekuti iyo query encoder yakadzimwa panguva yekutsvaga
    • Nekuti ndima yega yega yakavharwa yakazvimiririra pane chero mubvunzo
    • Nekuti ndima dzinochengetwa semavara manyoro chete
  4. Ndeapi manomano ekudzidzisa anoita kuti DPR iburitse mienzaniso yakawanda yakaipa zvakachipa?
    • Random label flipping
    • In-batch negatives, uchishandisa dzimwe ndima mubatch imwechete
    • Kudonhedza kunze hafu neuroni
    • Kunyora nemaoko ndima yese isiriyo
  5. For what vocabulary mismatch can learned DPR representations be useful compared with lexical matching alone?
    • The passage is unrelated but repeats the query's terms
    • Every query contains only an exact serial number
    • The encoder is guaranteed to retrieve the right answer for all inputs
    • A relevant passage expresses a query's idea using different words
  6. Ndechipi chishandiso chinowanzoshandiswa kuita DPR yepedyo-muvakidzani kutsvaga nekukurumidza pachiyero?
    • Indekisi yepedyo-yemuvakidzani senge FAISS
    • A spreadsheet sort
    • Injini yekutaura nguva dzose
    • A relationship database join
  7. Why can BM25-retrieved nonanswer passages be useful hard negatives when training DPR?
    • They guarantee that every retrieved passage is irrelevant
    • Their lexical overlap can make them challenging distractors that the retriever must distinguish from the answer passage
    • They remove the need for a positive answer passage
    • They force the passage encoder to count words without learning
  8. After changing DPR's passage encoder, what should happen to a stored passage-vector index?
    • Keep the old embeddings because encoder weights cannot affect vectors
    • Rename the index without recalculating any representation
    • Recompute the passage embeddings with the intended compatible encoder and update the index
    • Disable the query encoder and search raw filenames instead
