Out-of-Town Recommendation with Travel Intention Modeling
2021 · Proceedings of the AAAI Conference on Artificial Intelligence
Out-of-town recommendation is designed for those users who leave their home-town areas and visit the areas they have never been to before. It is challenging to recommend Point-of-Interests (POIs) for out-of-town users since the out-of-town …

Ontological Concept Structure Aware Knowledge Transfer for Inductive Knowledge Graph Embedding
2021
Conventional knowledge graph embedding methods mainly assume that all entities at reasoning stage are available in the original training graph. But in real-world application scenarios, newly emerged entities are always inevitable, which results in the …

Regularizing End-to-End Speech Translation with Triangular Decomposition Agreement
2021 · arXiv (Cornell University)
End-to-end speech-to-text translation (E2E-ST) is becoming increasingly popular due to the potential of its less error propagation, lower latency, and fewer parameters. Given the triplet training corpus $\langle speech, transcription, translation\rangle$, the conventional high-quality E2E-ST …
