Writers: Yuta Kikuchi, Sosuke Kobayashi

Preferred Networks (PFN) attended the 55th Annual Meeting of the
Association for Computational Linguistics (ACL 2017) in Vancouver, Canada. ACL is one of the largest conferences in the Natural Language Processing (NLP) field.

As in other Machine Learning research fields, use of deep learning in NLP is increasing. The most popular topic in NLP deep learning is sequence-to-sequence learning tasks. This model receives a sequence of discrete symbols (words) and learns to output a correct sequence conditioned by the input.

Writers: Richard Calland, Tommi Kerola

Preferred Networks (PFN) attended the CVPR 2017 conference in Honolulu, U.S., one of the flagship conferences for discussing research and applications in computer vision and pattern recognition. Computer vision is of major importance for our activities at PFN, including applications for autonomous driving, robotics, and of course products such as PaintsChainer. Modern computer vision is largely based on deep learning, which is relevant for our continued research and product development. In this blog post, we will briefly summarize trends from this conference, focusing on a few papers relevant to each topic.

ChainerCV Release

Yusuke Niitani

2017-08-14 11:07:10

We released ChainerCV: a utility library for computer vision in deep learning. This library aims at making the process of training and applying deep learning models for computer vision easier using Chainer. It contains high quality implementations of computer vision models, and tools that are necessary to conduct research in this field.

FCN-Based 6D Robotic Grasping for Arbitrary Placed Objects


2017-07-25 10:01:28

Hello! My name is Hitoshi Kusano. I participated in 2016 PFN summer internship program and have been a part-time engineer at PFN ever since, while also studying machine learning at Kyoto University. At PFN, my research topic was to teach an industrial robot how to pick up an object.

Based on the result of my work at PFN, I presented a paper titled ”FCN-Based 6D Robotic Grasping for Arbitrary Placed Objects” at the Learning and Control for Autonomous Manipulation Systems: The Role of Dimensionality Reduction workshop at ICRA 2017, the world’s biggest annual conference in robotics.
