To Adapt or Not to Adapt?

2018

Self-adaptive system (SAS) can adapt itself to optimize various key performance indicators in response to the dynamics and uncertainty in environment. In this paper, we present Debt Learning Driven Adaptation (DLDA), an framework that dynamically …

Efficient User Involvement in Semiautomatic Ontology Matching

2018 · IEEE Transactions on Emerging Topics in Computational Intelligence

Semiautomatic ontology matching poses a new challenge of how to implement an efficient user interactions. To address this challenge, we answer three questions in this paper: (1) when should we activate the interacting process; (2) …

An entanglement-based quantum network based on symmetric dispersive optics quantum key distribution

2019 · arXiv (Cornell University)

Quantum key distribution (QKD) is a crucial technology for information security in the future. Developing simple and efficient ways to establish QKD among multiple users are important to extend the applications of QKD in communication …

Parallel Exploration via Negatively Correlated Search

2019 · arXiv (Cornell University)

Effective exploration is a key to successful search. The recently proposed Negatively Correlated Search (NCS) tries to achieve this by parallel exploration, where a set of search processes are driven to be negatively correlated so …

Efficient and Effective Text Encoding for Chinese LLaMA and Alpaca

2023 · arXiv (Cornell University)

Large Language Models (LLMs), such as ChatGPT and GPT-4, have dramatically transformed natural language processing research and shown promising strides towards Artificial General Intelligence (AGI). Nonetheless, the high costs associated with training and deploying LLMs …

DUO: Stealthy Adversarial Example Attack on Video Retrieval Systems via Frame-Pixel Search

2023

Massive videos are released every day particularly through video-focused social media apps such as TikTok. This trend has fostered the quick emergence of video retrieval systems, which provide cloud-based services to retrieve similar videos using …

A Practical Human Labeling Method for Online Just-in-Time Software Defect Prediction

2023

Just-in-Time Software Defect Prediction (JIT-SDP) can be seen as an online learning problem where additional software changes produced over time may be labeled and used to create training examples. These training examples form a data …

Learn to optimize—a brief overview

2024 · National Science Review

ABSTRACT Most optimization problems of practical significance are typically solved by highly configurable parameterized algorithms. To achieve the best performance on a problem instance, a trial-and-error configuration process is required, which is very costly and …

Fast POI anomaly detection using a weakly-supervised temporal state regression network

2024 · Computational Urban Science

Abstract Point-of-interest (POI) is a fundamental data type of maps. Anomalous POIs would make maps outdated and lead to user-unfriendly location-based services, and thus should be discovered as fast as possible. Traditional POI anomaly detection …
