特征工程管道的主要目的是什么?

预览每个问题8 问题

当您参加测验时,就会出现答案和解释。

  1. 特征工程管道的主要目的是什么?
    • 存储经过训练的模型权重以供以后部署
    • 跨集群调度 GPU 作业
    • 将原始数据转换为模型使用的结构化特征
    • 加密静态数据集
  2. Why compare a dataset’s content hash instead of relying only on its filename?
    • A hash guarantees every record is accurate
    • The filename can stay the same while its stored contents change
    • A filename contains all transformations
    • Hashing removes access restrictions
  3. 特征管道通常表示为哪种结构?
    • 每次都必须重新运行的 SQL 查询的单一平面列表
    • 关系数据库表
    • 具有隐藏层的神经网络
    • 变换步骤的有向无环图 (DAG)
  4. A model behaves differently after a data update. What can version history help investigate?
    • Which data and transformation versions were used, with other runtime factors checked separately
    • A guaranteed identical rerun without environment records
    • Proof the update was authorized
    • A universal legal-compliance certificate
  5. 以下哪一个是专门用于特征存储或数据版本控制的示例工具?
    • Photoshop
    • Microsoft 字
    • FFmpeg
    • 盛宴(或DVC/LakeFS)
  6. 为什么在训练和生产过程中运行相同的特征逻辑很重要?
    • 降低云存储成本
    • 自动使模型更大、更精确
    • 确保模型看到一致的计算特征并避免训练/服务不匹配
    • 因为生产服务器无法运行Python
  7. A team has the same data and code but a changed random state. What remains possible?
    • Different computed outputs despite matching versions
    • Versioning forces every random choice to match
    • The dataset filename must change
    • All models become deterministic
  8. A reviewer asks which input record and transform produced a feature at a particular time. What record addresses that question?
    • Only the final prediction text
    • Feature lineage with source, transform version and timestamp
    • Only the dataset filename
    • Only a model parameter count
