备考CFA考试中的知识很多的，CFA考试题也是要练习的，考生在备考CFA考试中是不是掌握这些知识呢？今天跟着小编看看CFA一级考试题，对你备考CFA考试还是有帮助的哦！
练习1：L asks whether any information needs to be specified for the ML clustering algorithms no matter which one is used. K replies that only the distance measure that the algorithm will use and the hyperparameter, k, for k-means clustering need to be specified. K's reply is:
A. correct.
B. not correct, because other hyperparameters must also be specified.
C. not correct, because the feature set for describing the measure used to group holdings must also be specified.
解析：选C。除了指定距离度量和k-means的k值之外，无论选择哪种聚类算法，还必须指定用于根据相似性对持有物进行分组的特征集。
练习2：L further asks whether there would be an advantage to using k-means clustering as opposed to hierarchical clustering. K replies that in his opinion, hierarchical clustering is the more appropriate algorithm. The best justification for K’s preference for hierarchical clustering in his reply is that K is most likelygiving consideration to:
A. the speed of the algorithms.
B. the dimensionality of the dataset.
C. the need to specify the hyperparameter, k, in using a k-means algorithm.
解析：选C。超参数k的值，即可以划分的不同组的数量，是未知的，需要提前指定。使用分层算法，将观察结果分类成簇，无需事先输入任何信息。
备考CFA知识是很多的，考生备考CFA考试是需要通过一二三级考试的，一级考试是基础，如果一级知识点掌握不清楚的话，那在今后的CFA二三级考试中是不能很好的掌握的，所以前期的备考是关键，如果你有什么问题可以在线咨询老师。
