展望未来，冷冻电镜将朝着“更快、更真、更普及”的方向加速演进。在速度上，科研人员正努力将时间分辨能力从毫秒推进至微秒甚至纳秒级，以捕捉蛋白质折叠等超快生化反应；在精度上，分辨率将冲击0.1纳米，以清晰分辨单个原子的运动轨迹；在应用层面，可快速解析新发病毒结构，加快药物研发，还能指导纳米材料等创新研究。更值得期待的是，随着设备小型化、自动化和成本下降，桌面级冷冻电镜有望进入普通实验室、基层医院、学校课堂。到那时，冷冻电镜将会像常规显微镜一样，让更多人有机会看到精彩的微观世界，揭开更多生命的奥秘。
Finally, to wrap all this up ... I no longer use Windows to develop my games (aside from testing). I feel like this is in line with my general philosophy around using open source, cross-platform tools and libraries. I have found Windows increasingly frustrating to work with, their business practices gross, and their OS generally lacking. I grew up using Windows, but I switched to Linux full time around 3 years ago. And frankly, for programming video games, I have not missed it at all. It just doesn't offer me anything I can't do faster and more elegantly than on Linux.

如果不确定用哪个激活函数，隐藏层可以先用 ReLU，输出层按任务选择；训练中注意梯度情况，如果梯度消失或爆炸，再考虑替换或调整激活函数。
