UnverifiedFunctional programming views computation as the evaluation of mathematical functions, emphasizing immutability and the absence of side effects.67% similarUnverifiedFunction Calling refers to the model declaring, when generating a response, that a specific function needs to be called with specific parameters, which is then executed by an external system and the result returned to the model.67% similarUnverified对于确定性逻辑故障（模型输出缺陷）应搭建自纠错闭环，把结构化报错信息回传给大模型重新生成参数64% similarVerifiedThe underlying implementation of Function Calling does not involve the model actually executing a function; instead, the model outputs a structured description of the calling intent, and the host program actually dispatches the execution and returns the result to the model.64% similarVerifiedThe mathematical foundation of the backpropagation algorithm is the chain rule in calculus, which decomposes the gradient of a composite function into the product of local gradients at each layer, propagating the error signal layer by layer from the output layer to the input layer.64% similar
