These platforms provide online shopping services to users speaking over 20 languages across more than 100 countries worldwide. This competition aims to accelerate the development and application of LLMs in search technologies, particularly within multilingual e-commerce domains. The competition focuses on two core multilingual search tasks, supported by curated datasets designed to enhance these capabilities:

• Multilingual Query-Category Relevance Task: Determine the relevance between a user's search query and a specific product category.
• Multilingual Query-Item Relevance Task: Assess the alignment between a user's multilingual search query and a specific product listing.

2025 Finvolution Global Data Science Competition - Face Detection Challenge

hosted by The competition features a single track with one dedicated challenge: Deepfake Face Detection. We will provide a large-scale dataset comprising hundreds of thousands of facial forgery detection images. Compared to existing similar competitions, this event places greater emphasis on the cross-domain generalization capability of algorithms. Specifically, the competition will assess the ability of algorithms to adapt to application data distributions that differ from those encountered during training and to accurately detect forged facial images generated by unknown forgery techniques. All deadlines are at 11:59 PM (GMT+8), Beijing Time. More details can be found at the competition website: https://ai.ppdai.com/mirror/goToMirrorDetailSix?mirrorId=36
