We used to have to put words on the
web because computers could not see images. When all that a search engine had
to go by was the alt text input by a human and, maybe, the text surrounding an
image, understanding what it was exactly was a very hit and miss affair.
Words like Vectors
Semantic search changes all of that
and Google came up with a brilliant way of tackling it that is predicated on
language translation. Although the mathematics are complex the idea behind them
is not: Every language has a strict logical order in which words can be
associated with each other which is based upon:
- The internal grammatical logic of the language
- Popular convention
- Culture
- Use & usage paradigms
Images like Words
The traditional approach to image translation is
to take an image and try to match the elements within it to already known
entities in an attempt to devine the context. This was covered in my system article. Because an image
can appear in many variants of shape, size and perspective in a picture then a
probability assessment would be carried out to deduce whether some elements
‘detected’ in the picture should be there within that context.
Translated
Well, that cleverness need not be
lost any more. Google researchers realized that if they could use a computer’s
image-element reading ability, combined with advances in within an image and
translated that image into vector words which then used a traditional
language-to-language translation model to create a caption, the effect would
be, essentially a ‘translation’ of an image into language in a way that made
sense for both.
The net result of this approach is that complex
images can now be translated the same way complex sentences from one language
can be translated into another without loss of meaning.
