Core principles and definitions of MIL
Multi-Instance Learning (MIL) is a machine learning paradigm that deals with datasets comprising bags, where each bag contains multiple instances. The core principle of MIL is to learn from the relationship between bags and their instances rather than from individual instances. In MIL, bags are labeled instead of instances, and the label of a bag is determined by the presence or absence of a positive instance. This unique approach poses several challenges, such as ambiguous labeling and complex instance relationships, which require specialized algorithms and techniques for effective learning from MIL datasets.
Unique challenges posed by MIL, including ambiguous labeling and complex instance relationships
Multi-Instance Learning (MIL) presents unique challenges that set it apart from traditional supervised learning approaches.
