A soap factory’s scent-batch project must first decide it needs numeric vat logs plus a few still photos, pull them from the historian and a bench camera, and have two chemists tag “in spec / off.” Which data-preparation activity is that?
Select an answer to reveal the explanation.
Short Explanation
Decide the project needs numeric vat logs plus a few still photos, pull them from the historian and a bench camera, and have two chemists tag in spec / off. That is data acquisition: identify types, gather from sources, and label when the task is supervised. Tagging is not already feature extraction.
Full Explanation
Data acquisition identifies types, gathers from sources, and labels supervised work before cleaning. Feature extraction, EDA, and a Chapter 5 lab are later or different activities.
