Now, a pair of researchers from Kyushu University in Japan wanted to find out just how well artificial intelligence (AI) can engage in the proverbial book judging. It turns out, neural networks perform fairly well.The task was simple: can a deep neural network, which has four layers of up to 512 neurons each, correctly identify what genre a book belongs to just by analyzing its cover?Brian Kenji Iwana and Seiichi Uchida downloaded 137,788 unique book covers from 20 genres on Amazon.com. They trained their neural network using 80 percent of this data to recognize a book’s genre by looking at the cover image. To validate their model, they used 10 percent more from their dataset. The remaining 10 percent was used to actually test the neural network.
