LMSYS-Chat-1M: A Large-Scale Real-World LLM Conversation Dataset

ICLR 2024spotlight

Studying how people interact with large language models (LLMs) in real-world scenarios is increasingly important due to their widespread use in various applications. In this paper, we introduce LMSYS-Chat-1M, a large-scale dataset containing one million real-world conversations with 25 state-of-the-…

Judging LLM-as-a-Judge with MT-Bench and Chatbot Arena

NeurIPS 2023poster

Evaluating large language model (LLM) based chat assistants is challenging due to their broad capabilities and the inadequacy of existing benchmarks in measuring human preferences. To address this, we explore using strong LLMs as judges to evaluate these models on more open-ended questions. We exami…

RLlib Flow: Distributed Reinforcement Learning is a Dataflow Problem

NeurIPS 2021poster

Researchers and practitioners in the field of reinforcement learning (RL) frequently leverage parallel computation, which has led to a plethora of new algorithms and systems in the last few years. In this paper, we re-examine the challenges posed by distributed RL and try to view it through the lens…

Representing Long-Range Context for Graph Neural Networks with Global Attention

NeurIPS 2021poster

Graph neural networks are powerful architectures for structured datasets. However, current methods struggle to represent long-range dependencies. Scaling the depth or width of GNNs is insufficient to broaden receptive fields as larger GNNs encounter optimization instabilities such as vanishing gradi…

DataMix: Efficient Privacy-Preserving Edge-Cloud Inference

ECCV 2020poster

Deep neural networks are widely deployed on edge devices (g, for computer vision and speech recognition). Users either perform the inference locally (\ie, edge-based) or send the data to the cloud and run inference remotely (\ie, cloud-based). However, both solutions have their limitations: edge dev…
