LAION-BVD: A 10-Million-Hour Open Video Dataset for Multimodal Pre-training

This work presents LAION-BVD, a large-scale open video dataset for multimodal learning, which contains 1.3B platform-specific video URLs collected from CommonCrawl, and explores video frames as an alternative source of image-text data by extracting scene-changing frames.

Complex KDA: Understanding and Enhancing the Expressivity of Kimi Delta Attention

This work shows that Kimi Delta Attention (KDA) can realize 2D rotations by combining a single delta-rule transformation with a second reflection supplied by its channel-wise gate, and characterize the expressivity of CKDA and prove that every orthogonal diagonal-plus-rank-one matrix is exactly a CKDA transition matrix...

MultiSynt/MT: Trillion-Token Multi-Parallel Pre-Training Data Translated Across 36 Languages

This work introduces MultiSynt/MT, an open synthetic parallel corpus with approximately 4.8 trillion target-language tokens across 36 languages, produced by translating 100 billion high-quality Nemotron-CC tokens with Tower+ and OPUS-MT/HPLT-MT systems, and releases the corpus to support controlled research on multilin...

Deriving Scaling Laws for OpenEuroLLM Models: Learning Rate, Batch Size and Loss

This study establishes a first baseline and scaling procedure for the development of future OpenEuroLLM models, and characterize the dependence of loss on model capacity and dataset size, evaluating recently proposed scaling forms that explicitly model their interaction.
