Instance Learning

Instance learning (IL) addresses classification problems where labels are assigned to bags of instances, rather than individual data points, a common scenario in medical imaging and other fields with limited annotations. Current research focuses on improving IL model architectures, such as incorporating transformers and attention mechanisms to better capture instance relationships and mitigate biases stemming from spurious correlations between bag features and labels, while also exploring probabilistic and self-supervised approaches for improved robustness and interpretability. The development of effective IL methods holds significant promise for advancing weakly supervised learning across diverse applications, particularly in areas where obtaining fine-grained labels is costly or impractical.
