Transfer learning adapts a deep-learning network trained for one problem to a similar task with limited additional modeling effort. It is especially established for images and text, where reusable pretrained models are widely available. section 1.4
Tabular data makes this strategy harder to generalize: datasets vary widely, and broadly reusable pretrained solutions are difficult to obtain. Consequently, feature engineering often remains more influential for tabular machine learning. section 1.4
A practical contrast
A network trained on one image or text problem can be tweaked for a related task. A tabular-data model has fewer ready-made starting points because tabular problems differ substantially in structure and information. section 1.4
