Causally-Grounded Dual-Path Attention Intervention for Object Hallucination Mitigation in LVLMs

AAAI 2026technical

Object hallucination remains a critical challenge in Large Vision-Language Models (LVLMs), where models generate content inconsistent with visual inputs. Existing language-decoder based mitigation approaches often regulate visual or textual attention independently, overlooking their interaction as t

Dismantling Pathological Shortcuts: A Causal Framework for Faithful LVLM Decoding

ICML 2026poster

Large Vision-Language Models (LVLMs) exhibit sophisticated reasoning but remain susceptible to object hallucination. Deviating from the prevailing attention intensity assumption, we reveal a deeper dynamic structural misalignment: hallucination is triggered at decision-critical steps where specific …

Unlearning during Training: Domain-Specific Gradient Ascent for Domain Generalization

ICLR 2026poster

Deep neural networks often exhibit degraded performance under domain shifts due to reliance on domain-specific features. Existing domain generalization (DG) methods attempt to mitigate this during training but lack mechanisms to adaptively correct domain-specific reliance once it emerges. We propose…

Balancing Invariant and Specific Knowledge for Domain Generalization with Online Knowledge Distillation

IJCAI 2025

Recent research has demonstrated the effectiveness of knowledge distillation in Domain Generalization. However, existing approaches often overlook domain-specific knowledge and rely on an offline distillation strategy, limiting the effectiveness of knowledge transfer. To address these limitations, w

GloPER: Unsupervised Animal Pattern Extraction from Local Reconstruction

ICCV 2025poster

Traditional image segmentation methods struggle with fine-grained pattern extraction, especially in an unsupervised setting without labeled data. Shallow and deep learning approaches either lack structural coherence or focus on object-level segmentation rather than internal textures. Additionally, e…

Can Large Language Models Learn Independent Causal Mechanisms?

EMNLP 2024main

Despite impressive performance on language modelling and complex reasoning tasks, Large Language Models (LLMs) fall short on the same tasks in uncommon settings or with distribution shifts, exhibiting a lack of generalisation ability. By contrast, systems such as causal models, that learn abstract v…

Large Language Models Are Not Strong Abstract Reasoners

IJCAI 2024poster

Large Language Models have shown tremendous performance on a large variety of natural language processing tasks, ranging from text comprehension to common sense reasoning. However, the mechanisms responsible for this success remain opaque, and it is unclear whether LLMs can achieve human-like cogn…

Symmetric Self-Paced Learning for Domain Generalization

AAAI 2024technical

Deep learning methods often suffer performance degradation due to domain shift, where discrepancies exist between training and testing data distributions. Domain generalization mitigates this problem by leveraging information from multiple source domains to enhance model generalization capabilities…

Disentanglement of Latent Representations via Causal Interventions

IJCAI 2023poster

The process of generating data such as images is controlled by independent and unknown factors of variation. The retrieval of these variables has been studied extensively in the disentanglement, causal representation learning, and independent component analysis fields. Recently, approaches merging t…

Membership Inference via Backdooring

IJCAI 2022poster

Recently issued data privacy regulations like GDPR (General Data Protection Regulation) grant individuals the right to be forgotten. In the context of machine learning, this requires a model to forget about a training data sample if requested by the data owner (i.e., machine unlearning). As an essen…
