ACSeg: Adaptive Conceptualization for Unsupervised Semantic Segmentation

CVPR 2023highlight

Recently, self-supervised large-scale visual pre-training models have shown great promise in representing pixel-level semantic relationships, significantly promoting the development of unsupervised dense prediction tasks, e.g., unsupervised semantic segmentation (USS). The extracted relationship amo…

Fuzzy Positive Learning for Semi-Supervised Semantic Segmentation

CVPR 2023poster

Semi-supervised learning (SSL) essentially pursues class boundary exploration with less dependence on human annotations. Although typical attempts focus on ameliorating the inevitable error-prone pseudo-labeling, we think differently and resort to exhausting informative semantics from multiple proba…

LaPE: Layer-adaptive Position Embedding for Vision Transformers with Independent Layer Normalization

ICCV 2023poster

Position information is critical for Vision Transformers (VTs) due to the permutation-invariance of self-attention operations. A typical way to introduce position information is adding the absolute Position Embedding (PE) to patch embedding before entering VTs. However, this approach operates the sa…

Multi-granularity Interaction Simulation for Unsupervised Interactive Segmentation

ICCV 2023poster

Interactive segmentation enables users to segment as needed by providing cues of objects, which introduces human-computer interaction for many fields, such as image editing and medical image analysis. Typically, massive and expansive pixel-level annotations are spent to train deep models by object-o…

TG-VQA: Ternary Game of Video Question Answering

IJCAI 2023poster

Video question answering aims at answering a question about the video content by reasoning the alignment semantics within them. However, since relying heavily on human instructions, i.e., annotations or priors, current contrastive learning-based VideoQA methods remains challenging to perform fine-gr…

Text-Video Retrieval with Disentangled Conceptualization and Set-to-Set Alignment

IJCAI 2023poster

Text-video retrieval is a challenging cross-modal task, which aims to align visual entities with natural language descriptions. Current methods either fail to leverage the local details or are computationally expensive. What's worse, they fail to leverage the heterogeneous concepts in data. In this…

Locality Guidance for Improving Vision Transformers on Tiny Datasets

ECCV 2022poster

"While the Vision Transformer (VT) architecture is becoming trendy in computer vision, pure VT models perform poorly on tiny datasets. To address this issue, this paper proposes the locality guidance for improving the performance of VTs on tiny datasets. We first analyze that the local information,…

MMA Regularization: Decorrelating Weights of Neural Networks by Maximizing the Minimal Angles

NeurIPS 2020poster

The strong correlation between neurons or filters can significantly weaken the generalization ability of neural networks. Inspired by the well-known Tammes problem, we propose a novel diversity regularization method to address this issue, which makes the normalized weight vectors of neurons or filte…
