While some see this new prediction tech as like a new pipe tech that could improve all pipes, no matter their size, it is actually more like a tech only useful on very large pipes. Just as it would be a waste to force a pipe tech only useful for big pipes onto all pipes, it can be a waste to push advanced prediction tech onto typical prediction tasks.

Machine learning is all the rage, but most firms really just want the cachet of leading-edge tech; they could get their predictions with a simple regression and good clean data.

Google Translate invented its own shortcut

Google announced that their translation team discovered something interesting: after they turned over translation to a machine learning-enabled AI, it figured out its own way of translating.

After being taught to translate between English and Korean, then between Japanese and English, the AI invented its own fourth reference language that may draw upon deep-learning insights into a shared structure between the three languages. “This “interlingua” seems to exist as a deeper level of representation that sees similarities between a sentence or word in all three languages,” says TechCrunch.

Full explanation of the phenomenon from the Google team here.

[The bot] lives under the assumption that nothing will be novel, as if out of faith. It fields sentences by comparing them with those it knows, understanding phrasings using algorithms somewhat like Markov chains. Then, it assembles a response according to poetic constraints, rules and templates, or selects the best one from a list.

As in poetry, limitations give rise to creativity.
