Can Internet Videos Replace 3D Annotations? Introducing SceneVerse++ – the Largest Real‑World 3D Scene Dataset

The BIGAI team presents SceneVerse++, a massive real‑world indoor 3D scene dataset built from unlabelled internet videos via an automated pipeline, and demonstrates substantial zero‑shot and fine‑tuned performance gains on 3D detection, spatial VQA, and vision‑language navigation tasks.

Integrating Retrieval and Generation Tasks for Deep Semantic Matching in Xianyu Search

The paper introduces SimBert, a later‑fusion model that jointly trains a dual‑tower retrieval component and an auxiliary generation task on the item tower, using a two‑stage pre‑training and fine‑tuning pipeline, which yields a 3.6% relevance boost and reduces bad‑case rates in Xianyu search.
