微软研究院发布 GigaPath-Flash 与 GigaTIME-Flash 病理基础模型
微软研究院发布 GigaPath-Flash 和 GigaTIME-Flash 两个高效病理基础模型,均以 Apache 2.0 许可开源,权重和代码已在 Hugging Face 提供。GigaPath-Flash 由 22M 参数的 ViT-S 切片编码器和 21M 参数的 LongNet 全切片编码器组成,切片编码器从原 GigaPath ViT-g 蒸馏而来,在 PANDA 前列腺分级和 EBRAINS 脑肿瘤分型基准上以约 50 倍更少算力达到原 GigaPath 3% 以内的性能。GigaTIME-Flash 用该 ViT-S 编码器替换原 GigaTIME 的 CNN 骨干并配合轻量卷积解码器,经 LoRA 微调,在脑、乳腺、结肠和肺癌的分布内与分布外队列上空间蛋白预测质量持平或优于原版。两个模型均为研究用途,未经验证用于临床诊断、预后或治疗决策。
here these models work well and where they fall short. Downstream clinical applications will require additional multi-institutional and prospective validation. PODCAST SERIES Join Microsoft’s Doug Burger and guests as they dig into the fundamental truths about AI and how it will reshape the future. GigaPath and GigaTIME demonstrated what pathology foundation models can learn from whole slides and tumor tissue. GigaPath-Flash and GigaTIME-Flash are a step toward making those capabilities usable a
