The Nuclear Regulation Authority (NRA) on Sunday corrected its announcement that three drones were found flying over Kyushu Electric Power's Genkai nuclear plant in Saga Prefecture around 9 p.m. on Saturday. The corrected announcement stated that three lights that appeared to be drones were spotted at the time. It cannot be said with certainty that they were drones, NRA officials said. According to the NRA, no drones or flying objects have been found on or around the plant's grounds following the incident. There have also been no abnormalities at the plant, such as a leak of nuclear materials.

The baby food industry is realizing the importance of artificial intelligence (AI), to manage quality control. Japanese food producer Kewpie Corp. says that it is using Google's TensorFlow artificial intelligence, to quickly inspect ingredients that go into baby food products. This includes diced potatoes it uses in baby food, an ingredient that comes under most scrutiny in terms of safety since quality can greatly vary across batches of production and packaging. Kewpie tied up with analytics firm BrainPad Inc. to train machine learning algorithms to recognize the ingredients. The TensorFlow system was "educated" to identify the clean and healthy ingredients, by making it recognize as many as 18,000 photos of potatoes, which included acceptable and useable, as well as defective and unusable potatoes.
