VideoREPA: Learning Physics for Video Generation through Relational Alignment with Foundation Models

NeurIPS 2025poster

Recent advancements in text-to-video (T2V) diffusion models have enabled high-fidelity and realistic video synthesis. However, current T2V models often struggle to generate physically plausible content due to their limited inherent ability to accurately understand physics. We found that while the re…

Local Byte Fusion for Neural Machine Translation

ACL 2023long

Subword tokenization schemes are the dominant technique used in current NLP models. However, such schemes can be rigid and tokenizers built on one corpus may not adapt well to other parallel corpora. It has also been observed that in multilingual corpora, subword tokenization schemes oversegment low…

RASAT: Integrating Relational Structures into Pretrained Seq2Seq Model for Text-to-SQL

EMNLP 2022main

Relational structures such as schema linking and schema encoding have been validated as a key component to qualitatively translating natural language into SQL queries. However, introducing these structural relations comes with prices: they often result in a specialized model structure, which largely…
