One vat reports temperature in a 0–1 scaled column; another still stores raw °C. A third dumps a free-text note where the model needs a fixed-width row. Which preprocessing work is that?
Select an answer to reveal the explanation.
Short Explanation
One vat in a 0-1 scaled column, another still in raw C, and a free-text note where the model needs a fixed-width row is transforming, scaling, and normalizing. Columns have to mean the same thing and rows need a consistent format. A raw C column is not still a source to gather.
Full Explanation
Format transforms, scaling, and normalizing sit under preprocessing for consistency. Acquisition, k-fold, and an implementation task are different work.
