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.
