Unverified激活函数赋予深度网络拟合任意复杂非线性函数的理论能力，若无激活函数网络本质上仍是线性变换76% similarUnverifiedA Pure Function is a core concept in functional programming, referring to a function that always returns the same output given the same input and produces no side effects.68% similarUnverifiedThe composition of multiple linear transformations is still a linear transformation; therefore, a multi-layer network without nonlinear activation functions has expressive power equivalent to a single-layer linear model.66% similarVerifiedFunction Calling is the core mechanism for large models to interact with external systems, allowing the model to call predefined functions after identifying user intent.65% similar
