A permutation-invariant representation guarantees that the feature vector depends only on content and never on order

An identical set of rows should always yield the same feature vector. If relative to the target row-order is noise, by not following this rule the feature vector partially becomes a function of order - something that was just defined as noise.

Every data point is made of signal and noise a rule that's universal for any feature vector
Noise can be absolute (randomness) or relative (to some target) target-relative noise
What's noise and what's signal in a data point depends on how the target variable is defined when the order can be signal and when it can be noise
