FINDING perfect cut of tuna that melts in your mouth is something that fish buyers spend years of their life learning how to do. Now a Japanese advertising agency named Dentsu Inc. has developed an app called Tuna Scope that allows someone to do the same with little to no training.

The firm trained the machine learning algorithm that powers the software using thousands of images of tuna tail cross-sections. The cut can tell human buyers a lot about the quality of fish they’re about to purchase. In testing against human experts, Dentsu claims it found the app gave the same grade more than four out of five times.

The app is currently in use by conveyor belt sushi chain Kura Sushi. The restaurant buys the majority of its tuna outside of Japan. Part of the reason the company started using the app is that it allows its employees to grade tuna without traveling. (SD-Agencies)
