- 考虑如下数据集,其中Customer ID(顾客id),Transaction ID(事务id),Items Bought(购买 项)。如果将每个事务id看成一个购物篮,计算项集{e}, {b, d}, {b, d, e}的支持度:[img=581x242]17de909be1a6e52.png[/img] A: s({e}) =0.7 s({b, d})= 0.3 s({b, d, e})= 0.3 B: s({e}) =0.8 s({b, d})= 0. 1 s({b, d, e})= 0.1 C: s({e}) =0.8 s({b, d})= 0.2 s({b, d, e})= 0.2 D: s({e}) =0.6 s({b, d})= 0.4 s({b, d, e})= 0.3
- 侧向抽芯距S一般比塑件上侧凹、侧孔的深度或侧向凸台的高度S′大,用公式表示是( )。 A: S=S′+(0.2~0.3)mm B: S=S′+(90~100)mm C: S=S′+(0.5~0.6)mm D: S=S′+(5~10)mm
- Pre Delay主要是用来改善演唱的颤音效果。一般歌唱的颤音频率范围在( )之间。 A: 0.4~0.5 s B: 0.3~0.4 s C: 0.2~0.3 s D: 0.1~0.2 s
