🎉 𝗛𝗮𝗽𝗽𝘆 𝘁𝗼 𝘀𝗵𝗮𝗿𝗲 𝗺𝘆 𝗳𝗶𝗿𝘀𝘁 𝗿𝗲𝘀𝗲𝗮𝗿𝗰𝗵 𝘄𝗼𝗿𝗸! 🎉 Over the past months, I’ve had the pleasure of working with Alexander Heinlein and Eric C. Cyr on a very interesting project that has resulted in our preprint, "DDU-Net: A Domain Decomposition Based CNN for High-Resolution Image Segmentation on Multiple GPUs." This work, which builds upon and expands the results of my master’s thesis, is now available as a preprint on ArXiv! The work addresses the challenging task of high-resolution image segmentation, where using spatial contextual information across different scales is crucial for accuracy. We introduce the DDU-Net (Domain-Decomposition U-Net), a novel CNN architecture, based on the U-Net, where the full high-resolution image is divided into smaller subimages that can be processed largely independently on separate devices, allowing for efficient parallelization. To maintain global context, we incorporated a communication network that facilitates the exchange of low-resolution feature maps between the different devices. 𝗛𝗶𝗴𝗵𝗹𝗶𝗴𝗵𝘁𝘀: • DDU-Net partitions images into non-overlapping patches for independent processing on multiple GPUs. • A communication network ensures inter-subimage information exchange, preserving spatial context from other subimages. • Our model achieves performance equivalent to a baseline U-Net trained on the full image, but with improved efficiency and scalability. This work wouldn’t have been possible without the insightful discussions with Alexander and Eric. Thank you both for the great collaboration! 📝 Preprint: https://lnkd.in/eTkUbiBT 📚 Thesis: https://lnkd.in/eV-Mu69U #machinelearning #AI #deeplearning #imagesegmentation #highperformancecomputing #parallelcomputing
