クイズに答えると、答えと解説が表示されます。
- Where does the supervision signal in the described self-supervised examples come from?
- A requirement for no training objective
- Only new human semantic labels for every pretraining example
- A rule that examples contain no useful information
- The data and defined transformations of it
- Which input positions contribute prediction targets to the original BERT masked-language-model loss?
- The positions selected for the MLM prediction task
- Every position in the entire input regardless of selection
- Only the first position of each new sentence
- Only positions that appear after the final sentence boundary
- SimCLR のような対照学習では、「ポジティブ ペア」は次のとおりです。
- まったく関係のない2つの画像
- 人間が書いたラベルのペア
- 埋め込み空間内で近接している必要がある、同じ画像の 2 つの拡張ビュー
- データセットの 2 つのコピー
- What annotation requirement can self-supervised pretraining reduce in the described examples?
- The need for any usable input data
- Separate task-specific semantic labels for every pretraining example
- All computational cost by definition
- The need to assess downstream performance
- How can a representation learned through self-supervision be used for a later task?
- By evaluating a task head or adapting the representation through fine-tuning
- By assuming every target task requires no labels or validation
- By discarding all representations before making predictions
- By treating the pretraining loss as proof of every application's accuracy
- GPT スタイルのモデルの自己教師ありタスクは BERT のそれとどのように異なりますか?
- テキストは一切使用しません
- すべての単語に手動でラベルを付ける必要がある
- 文書の最初の単語のみを予測します
- マスクされたトークンを埋めるのではなく、次のトークンを予測します。
- In the original SimCLR framework, which component is discarded for the reported downstream representation use?
- The encoder representation itself
- The contrastive projection head
- All training inputs before pretraining begins
- The positive-pair source-image relationship
- When original BERT pretraining replaces a selected input position with a random token, what remains its loss target?
- The newly inserted random token
- The next sentence's first token in every case
- The original token before replacement
- No target, because every random replacement is omitted from training
