资源简介:
Dataset 1 is composed by two CSV files, defined as follow:
i. alpha1.csv (2561x648): This file contains the measured acoustic absorption coefficient data:
· The 648 rows correspond to the values of the acoustic absorption coefficient at each frequency, obtained by varying a set of categorical variables.
ii. target1.csv (648x14): This file contains 648 one-hot encoded vectors, one for each acoustic absorption measurement reported in alpha1.csv. Each row describes the conditions under which the corresponding measurement was performed:
· Columns [1,2]: material (2);
· Columns [3,4]: protective layer (2);
· Columns [5,6,7]: installation configuration (3);
· Columns [8,9,10,11]: relative humidity (4);
· Columns [12,13,14]: specimen number (3);
Note: The investigated frequency range spans from 250 Hz to 4250 Hz, with a resolution of 1.5625 Hz.
数据集1由两个CSV文件构成,具体说明如下:
i. alpha1.csv(2561×648):该文件存储实测声学吸声系数数据:
· 648行对应通过调整一组分类变量得到的各频率下的声学吸声系数数值。
ii. target1.csv(648×14):该文件包含648个独热编码向量,与alpha1.csv中记录的每一项声学吸声测量结果一一对应。每一行均描述了对应测量开展时的实验条件:
· 第1、2列:材料类型(共2种);
· 第3、4列:防护层(共2种);
· 第5、6、7列:安装配置(共3种);
· 第8、9、10、11列:相对湿度(共4种);
· 第12、13、14列:试样编号(共3种);
备注:本次研究所涉及的频率范围为250 Hz至4250 Hz,频率分辨率为1.5625 Hz。
