Revisiting Sparsity Constraint Under High-Rank Property in Partial Multi-Label Learning

CVPR 2026

Partial Multi-Label Learning (PML) extends the multi-label learning paradigm to scenarios where each sample is associated with a candidate label set containing both ground-truth labels and noisy labels. Existing PML methods commonly rely on two assumptions: sparsity of the noise label matrix and low

Generalized Tensor-based Parameter-Efficient Fine-Tuning via Lie Group Transformations

ICCV 2025poster

Adapting pre-trained foundation models for diverse downstream tasks is a core practice in artificial intelligence. However, the wide range of tasks and high computational costs make full fine-tuning impractical. To overcome this, parameter-efficient fine-tuning (PEFT) methods like LoRA have emerged…

Maintaining Structural Integrity in Parameter Spaces for Parameter Efficient Fine-tuning

ICLR 2025poster

Adapting pre-trained foundation models for various downstream tasks has been prevalent in artificial intelligence. Due to the vast number of tasks and high costs, adjusting all parameters becomes unfeasible. To mitigate this, several fine-tuning techniques have been developed to update the pre-train…

OPMapper: Enhancing Open-Vocabulary Semantic Segmentation with Multi-Guidance Information

NeurIPS 2025poster

Open-vocabulary semantic segmentation assigns every pixel a label drawn from an open-ended, text-defined space. Vision–language models such as CLIP excel at zero-shot recognition, yet their image-level pre-training hinders dense prediction. Current approaches either fine-tune CLIP—at high computatio…

Unleashing the Power of Task-Specific Directions in Parameter Efficient Fine-tuning

ICLR 2025poster

Large language models demonstrate impressive performance on downstream tasks, yet requiring extensive resource consumption when fully fine-tuning all parameters. To mitigate this, Parameter Efficient Fine-Tuning (PEFT) strategies, such as LoRA, have been developed. In this paper, we delve into the…

Partial Label Learning with a Partner

AAAI 2024technical

In partial label learning (PLL), each instance is associated with a set of candidate labels among which only one is ground-truth. The majority of the existing works focuses on constructing robust classifiers to estimate the labeling confidence of candidate labels in order to identify the correct one…

Tendency-driven Mutual Exclusivity for Weakly Supervised Incremental Semantic Segmentation

ECCV 2024poster

"Weakly Incremental Learning for Semantic Segmentation (WILSS) leverages a pre-trained segmentation model to segment new classes using cost-effective and readily available image-level labels. A prevailing way to solve WILSS is the generation of seed areas for each new class, serving as a form of pix…
