This document introduces deep reinforcement learning and provides some examples of its applications. It begins with backgrounds on the history of deep learning and reinforcement learning. It then explains the concepts of reinforcement learning, deep learning, and deep reinforcement learning. Some example applications are controlling building sway, optimizing smart grids, and autonomous vehicles. The document also discusses using deep reinforcement learning for robot control and how understanding the principles can help in problem setting.
This document provides an overview of POMDP (Partially Observable Markov Decision Process) and its applications. It first defines the key concepts of POMDP such as states, actions, observations, and belief states. It then uses the classic Tiger problem as an example to illustrate these concepts. The document discusses different approaches to solve POMDP problems, including model-based methods that learn the environment model from data and model-free reinforcement learning methods. Finally, it provides examples of applying POMDP to games like ViZDoom and robot navigation problems.

Preferred Networks is a Japanese AI startup founded in 2014 that develops deep learning technologies. They presented at CEATEC JAPAN 2018 on their research using convolutional neural networks for computer vision tasks like object detection. They discussed techniques like residual learning and how they have achieved state-of-the-art results on datasets like COCO by training networks on large amounts of data using hundreds of GPUs.
Preferred Networks was founded in 2008 and has focused on deep learning research, developing the Chainer and CuPy frameworks. It has applied its technologies to areas including computer vision, natural language processing, and robotics. The company aims to build AI that is helpful, harmless, and honest through techniques like constitutional AI that help ensure systems behave ethically and avoid potential issues like bias, privacy concerns, and loss of control.
Preferred Networks was founded in 2008 and has developed technologies such as Chainer and CuPy. It focuses on neural networks, natural language processing, computer vision, and GPU computing. The company aims to build general-purpose AI through machine learning and has over 500 employees located in Tokyo and San Francisco.
This document discusses Preferred Networks' open source activities over the past year. It notes that Preferred Networks published 10 blog posts and tech talks on open source topics and uploaded 3 videos to their Youtube channel. It also mentions growing their open source community to over 120 members and contributors across 3 major open source projects. The document concludes by reaffirming Preferred Networks' commitment to open source software, blogging, and tech talks going forward.
