【新闻稿】谷歌AI新星Omer Bar-Tal近日宣布转投初创公司Pika，担任其创始科学家，这一动向在人工智能领域引发了广泛关注。Bar-Tal在谷歌研究院以Student Researcher的身份工作了9个月，期间他专注于视频生成技术的研究，并在短短7个月内，作为共同一作推出了创新项目Lumiere。
Lumiere的亮点在于其提出的时空U-Net（STU-Net）架构，这一创新技术能够同时在空间和时间维度对视频进行下采样和上采样，从而在神经网络的中间层得到压缩的时空表示。据量子位报道，Lumiere在学习了3000万个视频后，具备了强大的功能，包括文本生成视频、视频编辑修复、图片转视频以及视频风格化等，展现了AI在多媒体处理上的巨大潜力。
尽管在完成这一杰出成就时，Bar-Tal可能还未硕士毕业，但他的学术才华和实践经验无疑为他在AI领域奠定了坚实的基础。Pika公司的这一引援，无疑为自身的技术创新注入了新的活力，同时也预示着视频处理和生成技术将迎来新的突破。我们期待Omer Bar-Tal在Pika的平台上，能够继续推动AI技术的边界，为业界带来更多惊喜。

**News Title:** “Google AI Rising Star Omer Bar-Tal Joins Pika as Founding Scientist, Leads Revolution in Lumiere Video Generation Technology”
**Keywords:** Google AI, Pika Founder, Lumiere Video
**News Content:** **Press Release** – Omer Bar-Tal, a prominent figure in Google’s AI landscape, recently announced his move to startup Pika, assuming the role of Founding Scientist. This transition has attracted substantial attention within the AI community. Bar-Tal spent 9 months at Google Research as a Student Researcher, focusing on video generation technology. In just 7 months, he co-led the groundbreaking project Lumiere.
The key to Lumiere lies in its Spatial-Temporal U-Net (STU-Net) architecture. This innovative technology performs down-sampling and up-sampling in both spatial and temporal dimensions, resulting in compressed spatiotemporal representations in the neural network’s intermediate layers. As reported by Quantum Bit, after learning from 30 million videos, Lumiere demonstrates impressive capabilities, including text-to-video generation, video editing and restoration, image-to-video conversion, and video stylization, highlighting the immense potential of AI in multimedia processing.
Despite potentially completing this remarkable feat before earning his master’s degree, Bar-Tal’s academic prowess and practical experience have solidly grounded him in the AI field. Pika’s acquisition of his talents promises to infuse new vitality into the company’s technological innovation and foreshadows breakthroughs in video processing and generation. We look forward to Omer Bar-Tal pushing the boundaries of AI technology at Pika, delivering more surprises to the industry.
