本文整理了Java中org.dkpro.tc.api.features.Feature.<init>()方法的一些代码示例，展示了Feature.<init>()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Feature.<init>()方法的具体详情如下：
包路径：org.dkpro.tc.api.features.Feature
类名称：Feature
方法名：<init>

Feature.<init>介绍

[英]Creates a feature that is aware if the value is a default value. This information is used when filling the feature store. A sparse feature store would not add a feature if it is a default value i.e. means a feature is not set
[中]创建一个可以识别该值是否为默认值的特征。填充功能存储时使用此信息。如果稀疏要素存储是默认值，即表示未设置要素，则不会添加要素
