Capturing helpful reviews from social media for product quality improvement: a multi-class classification approach

2017 · International Journal of Production Research

Reviews posted to social media are an effective source of information for helping quality managers to improve product quality. However, because helpful quality-related reviews may involve various aspects of product quality, previous studies confusing these …

CFHider: Control Flow Obfuscation with Intel SGX

2019

When a program is executed on an untrusted cloud, the confidentiality of the program's logics needs to be protected. Control flow obfuscation is a direct approach to obtain this goal. However, existing methods in this …

Learning to Guide Human Attention on Mobile Telepresence Robots with 360 degree Vision.

2021 · arXiv (Cornell University)

Mobile telepresence robots (MTRs) allow people to navigate and interact with a remote environment that is in a place other than the person's true location. Thanks to the recent advances in 360 degree vision, many …

Generalized Federated Learning via Sharpness Aware Minimization

2022 · arXiv (Cornell University)

Federated Learning (FL) is a promising framework for performing privacy-preserving, distributed learning with a set of clients. However, the data distribution among clients often exhibits non-IID, i.e., distribution shift, which makes efficient optimization difficult. To …

Learning the Target Network in Function Space

2024 · arXiv (Cornell University)

We focus on the task of learning the value function in the reinforcement learning (RL) setting. This task is often solved by updating a pair of online and target networks while ensuring that the parameters …

A systematic literature review of research on automatic speech recognition in EFL pronunciation

2025 · Cogent Education

To help EFL learners improve English pronunciation skills, researchers have recently turned to automatic speech recognition (ASR) technology. Despite some attempted review studies, relatively few have targeted ASR in an EFL setting. Therefore, the current …

Exploiting Inter-Session Information with Frequency-enhanced Dual-Path Networks for Sequential Recommendation

2026 · Proceedings of the AAAI Conference on Artificial Intelligence

Sequential recommendation (SR) aims to predict a user's next item preference by modeling historical interaction sequences. Recent advances often integrate frequency-domain modules to compensate for self-attention's low-pass nature by restoring the high-frequency signals critical for …
