激活函数虽然只是神经元里的一小步，但却是深度学习的一大步。没有它，深度学习就不会有今天的辉煌。它让神经网络从“线性堆叠”变成了真正的“非线性智能体”，能够处理复杂的视觉、语言和跨模态任务。
Ultrahuman Ring Pro hasn’t just got a far bigger battery, it’s been re-engineered from the ground up. The company’s Bhuvan Srinivasan explained the older hardware had been pushed to its limit, especially in terms of the data it could process. Consequently, the Pro is equipped with a dual core processor with on-device machine learning to better crunch the numbers your body is throwing out. Its memory has also been increased, holding up to 250 days of data before it needs to sync with your smartphone. As well as improvements to durability, the new ring is also easier to cut apart in the hopefully rare event your finger, or its battery, begins to swell.
