你们组里所设计专题必须被构想成一产品来实现，其产品需制定一套全面性的目标，且特别是需达到一套最低规格要求。

This project must be conceived in terms of a "product' that your team will design, with a set of overall objectives and especially with a set of minimum specifications which it must meet."

数据集内的每个属性都应该是规格化的，因此，每个值均除以该属性在数据集内的最高值与最低值间的差值。

Every attribute in the data set should be normalized, whereby each value is divided by the difference between the high value and the low value in the data set for that attribute.

例如，如果属性是年龄，且最高值为72，最低值为16，那么年龄32将被规格化为0.5714。

For example, if the attribute is age, and the highest value is 72, and the lowest value is 16, then an age of 32 would be normalized to 0.5714.
