They don't? One is a row in table (R^n) (order matters) and the other is a set of points (R^nxd).
If you consider the whole table, any dataSET is like point clouds.
- whatshisface 5y agoThe table is the point cloud the row is the point. The symmetry is permutations of rows or permutations of points.
- lurkmurk 5y agoIn which case would you use the whole table?
- whatshisface 5y agoWell yeah, there's no permutation symmetry between columns. (Unless there is...)
- elcomet 5y agoThen as parent said, almost all datasets are like point cloud, except time-series datasets.
- whatshisface 5y agoYeah, they are.
