Google is training AI to speak more naturally, and the early results are pretty entertaining. As spotted by Quartz, Google recently presented a paper describing how it's trying to train AI to naturally fill in the gaps between one sentence and another unrelated sentence. To do that, it's using a new neural network model that's been trained by analyzing 12,000 ebooks, primarily fiction — with a lot of those being romance novels.

グーグルはAIをさらに自然に話せるように訓練しています。そして初期の結果はとても面白いものになっています。 Quartzの記事では、グーグルが最近、ある文章と他の無関係な文章の間の差を自然に埋めるようにAIをトレーニングする方法について書いている論文を示しました。それを行うために、12000の電子書籍や小説を分析することによって訓練された、新しいニューラルネットワークのモデルを使用しています。多くの恋愛小説も含まれています。

The technique is working, insofar as it's getting better results than earlier methods did. But its results are still unnatural — and often, they end up creating what the researchers describe as "rather dramatic" sequences that are certainly inspired by the fiction Google's been feeding it.

初期の手法よりは良い結果を出すようになっているので、そのテクニックは動作しています。しかしその結果はまだ自然ではありません。そして、しばしば、それらはグーグルが与えたフィクションによって、明らかにインスパイヤされており、研究者が「なかなかドラマチック」なシーケンスだと言うようなものを創り出しています。

insofar - 限り

Here are some of the samples the paper provides. The bolded sentences are what the researchers told the AI to start with and stop on. I've cleaned up some of the punctuation, but otherwise this is straight from the machine:

it was her turn to blink.
it was hard to tell.
it was time to move on.
he had to do it again.
they all looked at each other.

"it’s all right here.
"everything is all right here.

we are all right here.
come here in five minutes.

i'm fine.
you're right.
"all right.
you're right.
okay, fine.
"okay, fine.
yes, right here.
no, not right now.
"no, not right now.
"talk to me right now.
please talk to me right now.
i’ll talk to you right now.
"i’ll talk to you right now.
"you need to talk to me now.
"but you need to talk to me now.

On one hand, its impressive how legitimately dramatic some of this stuff sounds. On the other hand, it's clear that romance authors will still find gainful employment for years to come.
