当您参加测验时,就会出现答案和解释。

  1. What does a text embedding supply for a language comparison task?
    • A required spoken audio recording
    • A verbatim dictionary entry for every coordinate
    • A numerical vector representation of text
    • Only a grammar-repair instruction
  2. In a representation trained to capture synonym similarity, what relationship is desirable for happy and joyful?
    • A relatively high similarity under the chosen scoring method
    • A mandatory identical vector for every word
    • A guarantee they are synonyms in every possible context
    • A requirement that neither word can be encoded
  3. Word2Vec 和 GloVe 等早期词嵌入的关键限制是什么?
    • 它们无法存储在计算机上
    • 他们只适用于图像
    • 他们不需要训练数据
    • 无论上下文如何,每个单词都有一个固定的向量,因此“银行”在任何地方都意味着相同的事物
  4. 现代上下文嵌入如何改进静态词嵌入?
    • 他们从表示中删除所有数字
    • 他们根据单词周围的句子赋予单词不同的向量
    • 他们只嵌入每个单词的第一个字母
    • 他们使每个单词的向量相同
  5. Which documented default similarity method does Sentence Transformers use for embedding comparison?
    • 余弦相似度
    • Alphabetical order
    • Document creation date
    • Character count alone
  6. What role can compatible text vectors play in a dense-retrieval RAG pipeline?
    • Guaranteeing every generated claim is correct
    • Eliminating the source corpus
    • Ranking candidate passages before they are supplied as context
    • Training a new language model on every query
  7. Which pooling strategy is the stated default in the original Sentence-BERT paper?
    • A mandatory maximum over every possible vocabulary item
    • Mean pooling of output token vectors
    • Concatenation of all corpus documents
    • Randomly selecting an unchanged input byte
  8. Which Sentence-BERT design allows stored sentences to be encoded before a new comparison sentence arrives?
    • Mandatory joint processing of every possible pair
    • Rebuilding encoder weights for each candidate
    • Encoding only the final comparison score
    • Independent sentence encoding through its siamese architecture
