Preferred Networks (PFN) will be organizing internship programs 2019 summer in Tokyo. In order to make the process smooth for students from outside of Japan, we have already opened an early bird application for them.

We are a growing startup with about 190 members based in Tokyo, Japan, focusing on applying deep learning to industrial problems such as autonomous driving, manufacturing, and bio-healthcare. Recently we revealed our plan towards personal robots. We are also actively developing the deep learning framework Chainer.

We look for brilliant students who have expertise on various topics, such as deep learning, robotics, computer vision, bioinformatics, human computer interaction, distributed computing, simulation, etc.

In previous years, by selecting highly capable interns and encouraging them to tackle challenging and important problems, some of the internship results have been published at top conferences such as ICML, ICLR or workshops at ICRA, ICCV, and NIPS.

During the internship, you will have a unique opportunity to collaborate with highly motivated experts for working on real-world applications of deep learning, while staying in Tokyo, one of the most attractive cities in the world.
