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？
I was days into my research before I finally found a clue. In an obscure document on the website of the International House of Pancakes Corporation there was a hint that the dark breakfast had been made. IHOP omelettes include pancake batter. While I cannot place IHOP omelettes exactly on the map, by interpolating between pancakes and omelettes, we can bound where they must occur, and confirm that the manifold possibilities do indeed pass through the Dark Breakfast Abyss.
