Reliability-Constrained Resource Allocation with Weighted SRLG for Distributed Clouds

2015 · Optical Fiber Communication Conference

We propose heuristics to allocate virtual machines among distributed data centers for a cloud request. Our objective is to minimize the maximum delay between selected data centers, while considering the reliability and computing resource constraints.

Earthformer: Exploring Space-Time Transformers for Earth System Forecasting

2022 · arXiv (Cornell University)

Conventionally, Earth system (e.g., weather and climate) forecasting relies on numerical simulation with complex physical models and are hence both expensive in computation and demanding on domain expertise. With the explosive growth of the spatiotemporal …

Chinese Lexical Substitution: Dataset and Method

2023

Existing lexical substitution (LS) benchmarks were collected by asking human annotators to think of substitutes from memory, resulting in benchmarks with limited coverage and relatively small scales. To overcome this problem, we propose a novel …

DGRO: Enhancing LLM Reasoning via Exploration-Exploitation Control and Reward Variance Management

2025 · arXiv (Cornell University)

Inference scaling further accelerates Large Language Models (LLMs) toward Artificial General Intelligence (AGI), with large-scale Reinforcement Learning (RL) to unleash long Chain-of-Thought reasoning. Most contemporary reasoning approaches usually rely on handcrafted rule-based reward functions. However, …
