In this paper we argue that in the traditional approach potentially interesting complex patterns with an unexpected relative increase of the target share remain undiscovered while on the other hand less surprising patterns are returned.
前一句：Subgroup discovery searches for descriptions of subsets in a dataset that differ from the total population with respect to a given target concept.
后一句：Therefore,we present a generalized approach on subgroup discovery,in which the target share in the subgroup is not compared to the target share in the total population,but to the expectations a user has given the knowledge of more general (simpler) patterns.

在本文中我们提出：在传统方法中,带来意料之外的目标份额相对增加的、或许很有趣的复杂模式尚未被发现,同时从另一方面说,不甚令人惊奇的模式被返回了.

不明白的再问哟,望及时采纳,多谢!

建议给点上下文

本文认为，在传统的方法感兴趣的潜在复杂的模式有一个意想不到的相对增加的目标仍然未被发现的，而另一方面不太令人惊讶的方式返回。
