Researchers at the Allen Institute and the University of Washington's Paul Allen School of Computer Science and Engineering have modified a neural network to create a natural language processing algorithm that generates, as well as detects, convincing fake articles.

The researchers tweaked OpenAI's popular GPT-2 network to produce the "Grover" program, which serves as both a fake-news "generator," and a "discriminator" to identify that false content.

Grover produces disinformation after being fed a massive volume of curated human-written online news texts, supporting a language model that the network utilizes to create its own texts.

The discriminator can identify Grover's fake text because it knows the generator's word-assembling "decoder" component chooses the most likely word combinations in a specific pattern.

The researchers said innovations like Grover offer an "exciting opportunity for defense against neural fake news," as "[t]he best models for generating neural disinformation are also the best models at detecting it."
