Dissecting Service Mesh Overheads

2022 · arXiv (Cornell University)

Service meshes play a central role in the modern application ecosystem by providing an easy and flexible way to connect different services that form a distributed application. However, because of the way they interpose on …

Time-Frequency Fusion Features-Based GSWOA-KELM Model for Gear Fault Diagnosis

2023 · Lubricants

To improve the accuracy of gear fault diagnosis and overcome the low diagnostic accuracy of the model caused by manual parameter selection, a combined diagnostic model based on time-frequency fusion features is combined with the …

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 …

Dual Graph Attention Networks for Deep Latent Representation of Multifaceted Social Effects in Recommender Systems

2019

Social recommendation leverages social information to solve data sparsity and cold-start problems in traditional collaborative filtering methods. However, most existing models assume that social effects from friend users are static and under the forms of …
