• Abstract: Complementary-label learning (CLL) is a weakly supervised learning paradigm for multiclass classification, where only complementary labels -- indicating classes an instance does not belong to -- are provided to the learning algorithm. Despite CLL's increasing popularity, previous studies highlight two main challenges: (1) inconsistent results arising from varied assumptions on complementary label generation, and (2) high barriers to entry due to the lack of a standardized evaluation platform across datasets and algorithms. To address these challenges, we introduce \texttt{libcll}, an extensible Python toolkit for CLL research. \texttt{libcll} provides a universal interface that supports a wide range of generation assumptions, both synthetic and real-world datasets, and key CLL algorithms. The toolkit is designed to mitigate inconsistencies and streamline the research process, with easy installation, comprehensive usage guides, and quickstart tutorials that facilitate efficient adoption and implementation of CLL techniques. Extensive ablation studies conducted with \texttt{libcll} demonstrate its utility in generating valuable insights to advance future CLL research.

  This paper explores the underexplored task of Continual Generalized Category Discovery (C-GCD) C-GCD aims to incrementally discover new classes from unlabeled data while maintaining the ability to recognize previously learned classes. We introduce a debiased learning framework, namely Happy, characterized by Hardness-aware prototype sampling and soft entropy regularization.

• Complementary Classifier Induced Partial Label Learning [54.61668156386079]
  In partial label learning (PLL), each training sample is associated with a set of candidate labels, among which only one is valid. In disambiguation, the existing works usually do not fully investigate the effectiveness of the non-candidate label set. In this paper, we use the non-candidate labels to induce a complementary classifier, which naturally forms an adversarial relationship against the traditional classifier.

Our results confirm that complementary-label augmentation can systematically improve empirical performance over state-of-the-art CLL models.

We discover that the biased-nature of human-annotated complementary labels and the difficulty to validate with only complementary labels are outstanding barriers to practical CLL.

  Partial-label learning (PLL) generally focuses on inducing a noise-tolerant multi-class by training on overly-annotated samples.
