Noise-Resistant Statistical Traffic Classification

2017 · IEEE Transactions on Big Data

Network traffic classification plays a significant role in cyber security applications and management scenarios. Conventional statistical classification techniques rely on the assumption that clean labelled samples are available for building classification models. However, in the …

Workflow scheduling in distributed systems under fuzzy environment

2019 · Journal of Intelligent & Fuzzy Systems

A well-managed time-constrained workflow scheduling is needed for improving system performance and end user satisfaction. Meanwhile, the intrinsic uncertainty in dynamic systems increases the difficulties of scheduling problem. Therefore, it is a great challenge to …

Optimizing RLHF Training for Large Language Models with Stage Fusion

2024 · arXiv (Cornell University)

We present RLHFuse, an efficient training system with stage fusion for Reinforcement Learning from Human Feedback (RLHF). Due to the intrinsic nature of RLHF training, i.e., the data skewness in the generation stage and the …
