恩,是一个多分类任务。通过六轴采集数据,特征提取用的您的脚本,提取了27*6个特征,通过feature selection方法筛出来50个特征,效果不是太好,正在查找原因。

@HaoWangDL 我们一般采用的数据格式:
一个大小为 M * (N + 1) 的矩阵,其中:
- M:数据样本的个数
- N:数据维度,比如你说的6轴,那么这里N=6
- 1:标签,比如走路是1,坐是2,等等

您的代码很详细,也可以看出数据格式。
如果我做运动类型识别,比如踢腿(横踢、侧踢、后踢等),您这有什么好的研究思路吗?
谢谢

这个感觉是一个很正常的分类任务,先收集数据做个简单的模型看一下?
from activityrecognition.
可能是:
- 特征提的不够多?是否遗漏了什么特征?
- 提完特征构建模型是否进行了归一化?
- 用的什么模型,是否可以换别的试一下?

@HaoWangDL 刚看到的一个开源时间序列库:https://arxiv.org/abs/1803.08118,你可以参考

谢谢王博士,我学习学习
