SVMLight 的输出包含每个分类实例的“预测值”。严格来说,这不是“分类分数”,但可以用作某种确定性的衡量标准。
有很多方法可以将其转换为某种类型的概率度量(我想这就是您在“分数”中提到的)。例如,请参阅 JS Platt 关于该主题的论文< /a>
SVMLight's output consists of a "prediced value" for each classified instance. Strictly speaking, this is not a "classification score", but can be used as some measure of certainty.
There are many methods of transforming this into some type of probability measure (I guess this is what you're referring to in 'scores'). For instance, see a paper by JS Platt on the topic
