Zero-Shot Meta-Learning for Small-Scale Data From Human Subjects

Julie Jiang;Kristina Lerman;Emilio Ferrara

2023 IEEE 11th International Conference on Healthcare Informatics (ICHI)
Year: 2023 | Conference Paper |
While developments in machine learning led to impressive performance gains on big data, many human subjects data are, in actuality, small and sparsely labeled. Existing methods applied to such data often do not easily generalize to out-of-sample subjects. Instead, models must make predictions on test data that may be drawn from a different distribution, a problem known as zero-shot learning. To ad...Show More
