近日，谷歌研究院的杰出青年科学家Omer Bar-Tal宣布转投新兴科技公司Pika，担任其创始科学家。Bar-Tal在谷歌的研究生涯中，以Student Researcher的身份工作了9个月，期间他与团队共同研发出创新的视频生成技术——Lumiere，并在短短7个月后，以共同一作的身份发布了这一重要成果。值得注意的是，此时的Bar-Tal尚未完成硕士学业。
Lumiere的问世，标志着视频处理技术的重大突破。该技术的核心在于创新的时空U-Net（STU-Net）架构，该架构能够同时在空间和时间维度上进行下采样和上采样，从而在中间层得到视频的压缩时空表示。这一创新使得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，极大地拓展了视频内容创作的可能性。
Bar-Tal的加盟，无疑将为Pika注入强大的科研动力，也将推动视频生成技术的进一步发展。Pika作为他的新舞台，有望在Bar-Tal的引领下，引领人工智能在视频处理领域的革命，为行业带来更多的创新应用。来源：量子位。

Title: Google AI Prodigy Omer Bar-Tal Joins Pika as Founding Scientist to Pioneer Video Generation Technology
Recently, Omer Bar-Tal, an outstanding young scientist from Google Research, announced his move to the emerging tech company Pika as a founding scientist. During his 9-month tenure at Google as a Student Researcher, Bar-Tal and his team developed the groundbreaking video generation technology called Lumiere, which he co-authored just 7 months later, even before completing his master’s degree.
The emergence of Lumiere signifies a significant breakthrough in video processing. The technology revolves around the innovative Spatio-Temporal U-Net (STU-Net) architecture, capable of simultaneous spatial and temporal downsampling and upsampling, resulting in a compressed spatiotemporal representation of videos in its middle layers. This innovation empowers Lumiere, after learning from 30 million videos, to perform various functions, including text-to-video generation, video editing and restoration, image-to-video conversion, and video stylization, vastly expanding the possibilities for video content creation.
Bar-Tal’s addition to Pika is set to infuse the company with robust research momentum and drive further advancements in video generation technology. With Bar-Tal at the helm, Pika is poised to spearhead an AI revolution in video processing, bringing about innovative applications to the industry. Source: Quantum Bit.
