Position: Code Benchmarks Should Prioritize Rigor, Reliability, and Reproducibility

ICML 2026poster

Code-related benchmarks play a critical role in evaluating large language models (LLMs), yet their quality fundamentally shapes how the com- munity interprets model capabilities. In the past few years, awareness of benchmark quality has grown. Yet, after a decade-scale (2014 - 2025) survey over 572 …

Reinforcing Real-world Service Agents: Balancing Utility and Cost in Task-oriented Dialogue

ICML 2026poster

The rapid evolution of Large Language Models (LLMs) has accelerated the transition from conversational chatbots to general agents. However, effectively balancing empathetic communication with budget-aware decision-making remains an open challenge. Since existing methods fail to capture these complex…

CodeCrash: Exposing LLM Fragility to Misleading Natural Language in Code Reasoning

NeurIPS 2025poster

Large Language Models (LLMs) have recently demonstrated strong capabilities in code-related tasks, but their robustness in code reasoning under perturbations remains underexplored. We introduce CodeCrash, a stress-testing framework with 1,279 questions from CRUXEVAL and LIVECODEBENCH, designed to ev…

IDInit: A Universal and Stable Initialization Method for Neural Network Training

ICLR 2025poster

Deep neural networks have achieved remarkable accomplishments in practice. The success of these networks hinges on effective initialization methods, which are vital for ensuring stable and rapid convergence during training. Recently, initialization methods that maintain identity transition within la…

Learning to Ask: When LLM Agents Meet Unclear Instruction

EMNLP 2025

Equipped with the capability to call functions, modern LLM agents can leverage external tools for addressing a range of tasks unattainable through language skills alone. However, the effective execution of these tools relies heavily not just on the advanced capabilities of LLM agents but also on pre

Split and Merge: Aligning Position Biases in LLM-based Evaluators

EMNLP 2024main

Large language models (LLMs) have shown promise as automated evaluators for assessing the quality of answers generated by AI systems. However, LLM-based evaluators exhibit position bias, or inconsistency, when used to evaluate candidate answers in pairwise comparisons, favoring either the first or s…

XMoE: Sparse Models with Fine-grained and Adaptive Expert Selection

ACL 2024findings

Sparse models, including sparse Mixture-of-Experts (MoE) models, have emerged as an effective approach for scaling Transformer models. However, they often suffer from computational inefficiency since a significant number of parameters are unnecessarily involved in computations by multiplying values…

Latent Space Factorisation and Manipulation via Matrix Subspace Projection

ICML 2020poster

We tackle the problem disentangling the latent space of an autoencoder in order to separate labelled attribute information from other characteristic information. This then allows us to change selected attributes while preserving other information. Our method, matrix subspace projection, is much simp…

Adapting Everyday Manipulation Skills to Varied Scenarios

ICRA 2019poster

We address the problem of executing tool-using manipulation skills in scenarios where the objects to be used may vary. We assume that point clouds of the tool and target object can be obtained, but no interpretation or further knowledge about these objects is provided. The system must interpret the…
