Listening to Users' Voice: Automatic Summarization of Helpful App Reviews

2022 · IEEE Transactions on Reliability

App reviews are crowdsourcing knowledge of user experience with the apps, providing valuable information for app release planning, such as major bugs to fix and important features to add. There exist prior explorations on app …

RARE: Robust Masked Graph Autoencoder

2023 · arXiv (Cornell University)

Masked graph autoencoder (MGAE) has emerged as a promising self-supervised graph pre-training (SGP) paradigm due to its simplicity and effectiveness. However, existing efforts perform the mask-then-reconstruct operation in the raw data space as is done …

FedHCDR: Federated Cross-Domain Recommendation with Hypergraph Signal Decoupling

2024 · arXiv (Cornell University)

In recent years, Cross-Domain Recommendation (CDR) has drawn significant attention, which utilizes user data from multiple domains to enhance the recommendation performance. However, current CDR methods require sharing user data across domains, thereby violating the …

FedDCSR: Federated Cross-domain Sequential Recommendation via Disentangled Representation Learning

2024 · Society for Industrial and Applied Mathematics eBooks

Cross-domain Sequential Recommendation (CSR) which leverages user sequence data from multiple domains has received extensive attention in recent years. However, the existing CSR methods require sharing origin user data across domains, which violates the General …

The Design of Fast Delta Encoding for Delta Compression Based Storage Systems

2024 · ACM Transactions on Storage

Delta encoding is a data reduction technique capable of calculating the differences (i.e., delta) among very similar files and chunks. It is widely used for various applications, such as synchronization replication, backup/archival storage, cache compression, …
