问题如下:

In the use of machine learning (ML):

选项:

A.some techniques are termed “black box” due to data biases. B.human judgment is not needed because algorithms continuously learn from data. C.training data can be learned too precisely, resulting in inaccurate predictions when used with different datasets.

解释:

Overfitting occurs when the ML model learns the input and target dataset too precisely. In this case, the model has been “over trained” on the data and is treating noise in the data as true parameters. An ML model that has been overfitted is not able to accurately predict outcomes using a different dataset and may be too complex.

black box 是指的什么呢?

嗨,爱思考的PZer你好:


“black box”在这里指的是一个形象的描述,在我们普通人的角度看起来,机器学习具体的算法就像这个黑盒子一样,并没有一个显性的编程,因为数学家和科学家都已经写好了这个算法,我们只要直接运用就好了,并不知道具体的算法是怎么编写的。
