关于函数的参数传递(parameter passing),以下选项中描述错误的是A.实际参数是函数调用时提供的参数B.形式参数是函数定义时提供的参数C.Python参数传递时不构造新数据对象,而是让形式参数和实际参数共享同一对象D.函数调用时,需要将形式参数传递给实际参数相关知识点: ...
对于参数传递,我总是用传值或者传址来理解,但在《Python基础教程》中建议我们用这样的方法来理解Python中的参数传递:(以Demo1为例说明) 1.#demo1 again:2.defchange1(x):3. x = [1, 2]4. 5.a = [10, 20] 6.print('a is {0}'.format(a))7.change1(a)8.print('a is {0}'.format(a)...

Consistency with Scikit-Learn API: Change less than 5 lines in a standard Scikit-Learn script to use the API [example]. Modern tuning techniques: tune-sklearn allows you to easily leverage Bayesian Optimization, HyperBand, BOHB, and other optimization techniques by simply toggling a few parameter...
After exploration and investigation, it is regrettable that MATLAB currently cannot effectively pass the handle of the optimization objective function to the Optuna framework, especially for complex objective functions that may involve

In this regard, PEFT methods only fine-tune a small number of (extra) model parameters, thereby greatly decreasing the computational and storage costs. Recent State-of-the-Art PEFT techniques achieve performance comparable to that of full fine-tuning....
