Weka无法识别Opensmile生成的ARFF文件格式，表示“无法确定ARFF的结构”

Question

目前我正在为情感识别工作。我已经使用opensmile工具包从标记数据中提取了音频特征，这些数据是以ARFF格式生成的。但是当我尝试在weka中加载这个ARFF文件进行分类时，Weka说它无法确定ARFF的结构。我对机器学习方法很新。所以，请指导我解决这个问题。

ARFF档案：

 @relation SMILEfeaturesLive

@attribute name string

在WEKA中生成错误：无法将结构确定为arff（原因：Java.io.IOException：无有效属性类型或无效枚举，读取令牌[愤怒]，第993行）。

Answer 1

在'@attribute pcm_intensity_sma_iqr1-3 numeric'之后，你可以添加class属性

@attribute class {anger}
