CroPS: Improving Dense Retrieval with Cross-Perspective Positive Samples in Short-Video Search

AAAI 2026technical

Dense retrieval has become a foundational paradigm in modern search systems, especially on short-video platforms. However, most industrial systems adopt a self-reinforcing training pipeline that relies on historically exposed user interactions for supervision. This paradigm inevitably leads to a fil

Machine-Created Universal Language for Cross-Lingual Transfer

AAAI 2024technical

There are two primary approaches to addressing cross-lingual transfer: multilingual pre-training, which implicitly aligns the hidden representations of various languages, and translate-test, which explicitly translates different languages into an intermediate language, such as English. Translate-tes…

Sparse Double Descent: Where Network Pruning Aggravates Overfitting

ICML 2022spotlight

People usually believe that network pruning not only reduces the computational cost of deep networks, but also prevents overfitting by decreasing model capacity. However, our work surprisingly discovers that network pruning sometimes even aggravates overfitting. We report an unexpected sparse double…
