well posed problem是什么意思

网络释义

用法例句

In the fields of chemistry and chemical engineering, most of the data mining problems are actually "ill-posed problems" .

化学、化工领域中多数数据处理问题属于数学中的“不适定问题”(ill-posed problem),而传统的化学计量学算法如线性和非线性回归,人工神经网络等忽略了这一特点,将其作为“适定问题”(well-posed problem)求解,是引发数据处理中“过拟合”问题的重要原因。
