You can select an individual value from an input range using the CHOOSE function, which makes the selection based upon the position of the value in the series. The CHOOSE function takes two arguments.

可以使用CHOOSE函数从输入范围中选择单一值，它根据值在序列中的位置做出选择。

Optimization of feature selection, we select area, perimeter, long axis, short axis, Euler number, geometric moments, and a total of 12 feature parameters as input vector.

优化特征选择，选定面积、周长、长轴、短轴、欧拉数、几何矩等共12个特征参数作为神经网络输入向量进行分类试验。

It's a much lighter product, at 1.3 pounds (down from 1.58), and although it uses a heavier-duty Atom processor, battery life is said to top out at about 10 hours. (The original lasted eight in our usual test.) Like the OG version, it allows for pen input on select models, but of course, Windows comes ready-made with a larger selection of apps where a pen might actually be useful.
