| As an archive that supplements my personal archive, and the

| in this very thread for HN, and others such as the one used
| for https://github.com/afiodorov/hn-search
|
| The way to eliminate your comments would be to take over
| world government, use your copy of the archives of the
| entire internet in order to track down the people who most
| likely have created their own copies, and to utilize
| worldwide swat teams with trained searchers, forensics
| experts and memory-sniffing dogs. When in doubt, just fire
| missiles at the entire area. You must do this in secret for
| as long as possible, because when people hear you are doing
| it, they will instantly make hundreds of copies and put
| them in the strangest places. You will have to shut down
| the internet. When you are sure you have everything, delete
| your copy. You still may have missed one.

|
| Embeddings are encodings of shared abstract concepts
| statistically inferred from many works or expressions of
| thoughts possessed by all humans.
|
| With text embeddings, we get a many-to-one, lossy map: many
| possible texts ~ one vector that preserves some structure
| about meaning and some structure about style, but not enough
| to reconstruct the original in general, and there is no
| principled way to say <<this vector is derived specifically
| from that paragraph by authored by XYZ>>.
|
| Does the encoded representation of the abstract concepts
| represent the derivate work? If yes, then every statement
| ever made by a human being represents the work derivative of
| someone else's by virtue of learning how to speak in the
| childhood - they create a derivative work of all prior
| speakers.
|
| Technically, the3re is a strong argument against treating
| ordinary embedding vectors as derivative works, because:
|
| - Embeddings are not uniquely reversible and, in general, it
| is not possible reconstruct the original text from the
| embedding;
|
| - The embedding is one of an uncountable number of vectors in
| a space where nearby points correspond to many different
| possible sentences;
|
| - Any individual vector is not meaningfully <<the same>> as
| the original work in the way that a translation or an
| adaptation is.
|
| Please do note that this is the philosophical take and it
| glosses over the _legally_ relevant differences between human
| and machine learning as the legal question ultimately depends
| on statutes, case law and policy choices that are still
| evolving.
|
| Where it gets more complicated.
|
| If the embeddings model has been trained on a large number of
| languages, it makes the cross-lingual search easily possible
| by using an abstract search concept in any language that the
| model has been trained on. The quality of such search results
| across languages X, Y and Z will be directly proportional to
| the scale and quality of the corpus of text that was used in
| the model training in the said languages.
|
| Therefore, I can search for <<the meaning of life>>[0] in
| English and arrive at a highly relevant cluster of search
| results written in different languages by different people at
| different times, and the question becomes is <<what exactly
| it has been statistically[1] derived from?>>.
|
| [0] The cross-lingual search is what I did with my engineers
| last year to our surprise and delight of how well it actually
| worked.
|
| [1] In the legal sense, if one can't trace a given vector
| uniquely back to a specific underlying copyrighted
| expression, and demonstrate substantial similarity of
| expression rather than idea, the <<derivative work>> argument
| in the legal sense becomes strained.
