在深度学习中，激活函数（Activation Function）是神经网络的灵魂。它不仅赋予网络非线性能力，还决定了训练的稳定性和模型性能。那么，激活函数到底是什么？为什么我们非用不可？有哪些经典函数？又该如何选择？
1. I wrote a markdown file with the specification of what I wanted to do. Just English, high level ideas about the scope of the Z80 emulator to implement. I said things like: it should execute a whole instruction at a time, not a single clock step, since this emulator must be runnable on things like an RP2350 or similarly limited hardware. The emulator should correctly track the clock cycles elapsed (and I specified we could use this feature later in order to implement the ZX Spectrum contention with ULA during memory accesses), provide memory access callbacks, and should emulate all the known official and unofficial instructions of the Z80.，详情可参考搜狗输入法2026
