Chainer v2.0.0 and our future development plans

We have released Chainer v2.0.0 today! This is the first major update of Chainer. The detailed updates from the beta release can be found in the release notes. You can also find the differences between v1 and v2 in the Upgrade Guide. Note that the repository has been moved to chainer/chainer. Any access to the old URL (including Git operations) will automatically be redirected to the new one.

Performance comparison of LSTM with and without cuDNN(v5) in Chainer

We compare the performance of an LSTM network both with and without cuDNN in Chainer. The NVIDIA CUDA® Deep Neural Network library (cuDNN) is a GPU-accelerated library of primitives for deep neural networks. cuDNN provides highly tuned implementations for standard routines such as LSTM, CNN.

ChainerRL - Deep Reinforcement Learning Library

Chainer-based deep reinforcement learning library, ChainerRL has been released.

Performance of Distributed Deep Learning using ChainerMN

At Deep Learning Summit 2017 in San Francisco on this January, PFN announced advancements on distributed deep learning using Chainer in multi-node environment. In this post, I would like to explain the detail of the announcement.

Research projects using Chainer

Recently we found some great research projects that are using Chainer for their algorithm implementations and experiments. We searched for such publicly available projects on arXiv and summarized them here as a table that lists papers along with their URL links: Research projects using Chainer.

Plan of v2

We are planning the first major update of Chainer! It is currently scheduled for next March or April.

New release cycle

Starting from the release of v1.18.0, we will have one release every four weeks instead of the current cycle of one release every two weeks.
