We tried related ideas but found that the transfer assumption rarely held well enough to be useful. Useful to keep in mind to potentially simplify models, with care..
'Small Data' Is Also Crucial for Machine Learning
By Scientific American, October 19, 2021
The existence of techniques such as transfer learning does not seem to have reached the awareness of policy makers and business leaders making decisions about AI funding and adoption.....
Some of the most prominent artificial intelligence (AI) breakthroughs in the past decade have relied on enormous data sets. But AI is not only about large data sets; research in "small data" approaches has grown extensively over the past decade—with so-called transfer learning as an especially promising example.
Small-data approaches such as transfer learning offer numerous advantages over more data-intensive methods. Enabling the use of AI with less data can bolster progress in areas where little or no data exists, such as in forecasting natural hazards that occur relatively rarely or in predicting the risk of disease for a population set that does not have digital health records.
