Image is All You Need: Towards Efficient and Effective Large Language Model-Based Recommender Systems

ICLR 2026poster

Large Language Models (LLMs) have recently emerged as a powerful backbone for recommender systems. Existing LLM-based recommender systems take two different approaches for representing items in natural language, i.e., Attribute-based Representation and Description-based Representation. In this work,…

SelfJudge: Faster Speculative Decoding via Self-Supervised Judge Verification

ICML 2026poster

Speculative decoding accelerates LLM inference by verifying candidate tokens from a draft model against a larger target model. Recent "judge'' decoding boosts this process by relaxing verification criteria by accepting draft tokens that may exhibit minor discrepancies from target model output, but e…

Is Safety Standard Same for Everyone? User-Specific Safety Evaluation of Large Language Models

EMNLP 2025

As the use of large language model (LLM) agents continues to grow, their safety vulnerabilities have become increasingly evident. Extensive benchmarks evaluate various aspects of LLM safety by defining the safety relying heavily on general standards, overlooking user-specific standards. However, saf

RA-SGG: Retrieval-Augmented Scene Graph Generation Framework via Multi-Prototype Learning

AAAI 2025technical

Scene Graph Generation (SGG) research has suffered from two fundamental challenges: the long-tailed predicate distribution and semantic ambiguity between predicates. These challenges lead to a bias towards head predicates in SGG models, favoring dominant general predicates while overlooking fine-gra…

Training Robust Graph Neural Networks by Modeling Noise Dependencies

NeurIPS 2025poster

In real-world applications, node features in graphs often contain noise from various sources, leading to significant performance degradation in GNNs. Although several methods have been developed to enhance robustness, they rely on the unrealistic assumption that noise in node features is independent…

Weakly Supervised Video Scene Graph Generation via Natural Language Supervision

ICLR 2025poster

Existing Video Scene Graph Generation (VidSGG) studies are trained in a fully supervised manner, which requires all frames in a video to be annotated, thereby incurring high annotation cost compared to Image Scene Graph Generation (ImgSGG). Although the annotation cost of VidSGG can be alleviated by…

Adaptive Self-training Framework for Fine-grained Scene Graph Generation

ICLR 2024poster

Scene graph generation (SGG) models have suffered from inherent problems regarding the benchmark datasets such as the long-tailed predicate distribution and missing annotation problems. In this work, we aim to alleviate the long-tailed problem of SGG by utilizing unannotated triplets. To this end, w…

LLM4SGG: Large Language Models for Weakly Supervised Scene Graph Generation

CVPR 2024poster

Weakly-Supervised Scene Graph Generation (WSSGG) research has recently emerged as an alternative to the fully-supervised approach that heavily relies on costly annotations. In this regard studies on WSSGG have utilized image captions to obtain unlocalized triplets while primarily focusing on groundi…

Semantic Diversity-aware Prototype-based Learning for Unbiased Scene Graph Generation

ECCV 2024poster

"The scene graph generation (SGG) task involves detecting objects within an image and predicting predicates that represent the relationships between the objects. However, in SGG benchmark datasets, each subject-object pair is annotated with a single predicate even though a single predicate may exhib…

Unbiased Heterogeneous Scene Graph Generation with Relation-Aware Message Passing Neural Network

AAAI 2023technical

Recent scene graph generation (SGG) frameworks have focused on learning complex relationships among multiple objects in an image. Thanks to the nature of the message passing neural network (MPNN) that models high-order interactions between objects and their neighboring objects, they are dominant rep…
