Complementary Aspect-Based Opinion Mining

2017 · IEEE Transactions on Knowledge and Data Engineering

Aspect-based opinion mining is finding elaborate opinions towards a subject such as a product or an event. With explosive growth of opinionated texts on the Web, mining aspect-level opinions has become a promising means for …

Temporal Item Embedding with Static Similarity Regularization for Sequential Recommendation

2018

Recommender systems have attracted a significant amount of research interests in recent years. Traditional methods such as content-based approaches and collaborative filtering approaches mainly focus on modeling the general user preference by using the user's …

Hacking single-photon avalanche detectors in quantum key distribution via pulse illumination

2020 · Optics Express

Quantum key distribution (QKD) has been proved to be information-theoretically secure in theory. Unfortunately, the imperfect devices in practice compromise its security. Thus, to improve the security property of practical QKD systems, a commonly used …

Interpretability is a Kind of Safety: An Interpreter-based Ensemble for Adversary Defense

2020

While having achieved great success in rich real-life applications, deep neural network (DNN) models have long been criticized for their vulnerability to adversarial attacks. Tremendous research efforts have been dedicated to mitigating the threats of …

Rethinking Targeted Adversarial Attacks For Neural Machine Translation

2024 · arXiv (Cornell University)

Targeted adversarial attacks are widely used to evaluate the robustness of neural machine translation systems. Unfortunately, this paper first identifies a critical issue in the existing settings of NMT targeted adversarial attacks, where their attacking …

Self-Updatable Large Language Models by Integrating Context into Model Parameters

2024 · arXiv (Cornell University)

Despite significant advancements in large language models (LLMs), the rapid and frequent integration of small-scale experiences, such as interactions with surrounding objects, remains a substantial challenge. Two critical factors in assimilating these experiences are (1) …

Fine-grained control strategy for high-concurrency transactions in the consortium chain Hyperledger Fabric

2025 · Journal of Computing and Electronic Information Management

Hyperledger Fabric is a consortium chain framework that is widely used at home and abroad. When conducting business with Fabric technology, high-concurrency transaction conflicts are often encountered. To optimize the high concurrent transaction processing performance …

High-efficiency Weak-trace-free Counterfactual Communication via Quantum Zeno Effect

2025 · arXiv (Cornell University)

The quantum Zeno effect, which inhibits quantum state evolution via repeated weak measurements, significantly enhances the efficiency of interaction-free measurement (IFM). This fundamental mechanism facilitates high-efficiency counterfactual quantum communication, enabling information delivery without particle transmission …
