Flexible Group Count Enables Hassle-Free Structured Pruning

CVPR 2025poster

Densely structured pruning methods -- which generate pruned models in a fully dense format, allowing immediate compression benefits without additional demands -- are evolving owing to their practical significance. Traditional techniques in this domain mainly revolve around coarser granularities, suc…

LoRATK: LoRA Once, Backdoor Everywhere in the Share-and-Play Ecosystem

EMNLP 2025

Backdoor attacks are powerful and effective, but distributing LLMs without a proven track record like ‘meta-llama‘ or ‘qwen‘ rarely gains community traction. We identify LoRA sharing as a unique scenario where users are more willing to try unendorsed assets, since such shared LoRAs allow them to enj

ReasonerRank: Redefining Language Model Evaluation with Ground-Truth-Free Ranking Frameworks

ACL 2025finding

Large Language Models (LLMs) are increasingly adopted across real-world applications, yet traditional evaluations rely on expensive, domain-specific ground-truth labels that are often unavailable or infeasible. We introduce a ground-truth-free evaluation framework focused on reasoning consistency an…

An Information Fusion Approach to Learning with Instance-Dependent Label Noise

ICLR 2022poster

Instance-dependent label noise (IDN) widely exists in real-world datasets and usually misleads the training of deep neural networks. Noise transition matrix (NTM) (i.e., the probability that clean labels flip into noisy labels) is used to characterize the label noise and can be adopted to bridge the…

Table2Graph: Transforming Tabular Data to Unified Weighted Graph

IJCAI 2022poster

Learning useful interactions between input features is crucial for tabular data modeling. Recent efforts start to explicitly model the feature interactions with graph, where each feature is treated as an individual node. However, the existing graph construction methods either heuristically formula…

Dirichlet Energy Constrained Learning for Deep Graph Neural Networks

NeurIPS 2021poster

Graph neural networks (GNNs) integrate deep architectures and topological structure modeling in an effective way. However, the performance of existing GNNs would decrease significantly when they stack many layers, because of the over-smoothing issue. Node embeddings tend to converge to similar vecto…
