| Nov 3, 2019 at 5:06 | comment | added | Quinn Culver | @HasanIqbal What do you think about the probability distribution on $\mathbb{R}^4$ induced by function $(x_1, x_2, x_3) \mapsto (x_1, x_2,x_3, x_1 / x_2)$? Could that be considered effectively the same as enlarging the sample space? | |
| Aug 7, 2019 at 12:53 | comment | added | JJJohn | @HasanIqbal What does "It's exhaustive" mean? Take the iris dataset as example, there are 150 instances and 4 attributes? Would you please illustrate "It's exhaustive, feature spaces aren't"? | |

| Apr 5, 2016 at 12:56 | comment | added | QuestionEverything | I would say that, as Pilon's example shows, feature space can be increased by extracting some new features. Sample space in probability can't. It's exhaustive, feature spaces aren't. | |

Replacing "creation" eith "extraction". More accurate term from literature.

| Dec 23, 2012 at 4:25 | comment | added | Cam.Davidson.Pilon | It's is very similar, if not identical. If you consider the data-generating distribution $D$, then the feature-space is identical to the support of $D$. | |
