MXNet is a multi-language machine learning library to ease the development of ML algorithms, especially for deep neural networks. It blends declarative symbolic expression with imperative tensor computation, and also offers efficient auto differentiation to derive
gradients. Besides the computational and memory efficiency, MXNet is lightweight and portable. It can run on various systems, including most normal computer systems and mobile platforms, like Android.

The MXNet R package brings flexible and efficient GPU computing and state-of-art deep learning to R. It enables users to write seamless tensor/matrix computation with multiple GPUs in R. It also enables users to construct and customize the state-of-art deep learning models in R, and apply them to tasks such as image classification and data science challenges.

Due to the portable design, the MXNet R package can be installed and used on all operating systems supporting R, including Linux, OSX and Windows. In this talk I will provide a brief overview of the MXNet platform. With demos of state-of-art deep learning models, users can build and modify deep neural networks according to their own need easily. At the same time, the GPU backend will ensure the efficiency of all computing work. The MXNet package allows user to save fine-tuned models into json files and deploy models on large systems through its C++ APIs.

COS沙龙开始试运行,有钱的捧个钱场,没钱的回家取钱来捧个钱场
统计之都(COS,http://cos.name)海外线上沙龙是COS海外会员的线上学习交流活动,每期由一位或多位嘉宾通过视频形式主讲分享,主持人和嘉宾可以通过视频直接互动交流,其他参加沙龙活动的观众可以通过Google+观看直播并以文本形式提问,无法在直播时间看视频的听众也可以随后在Youtube上看重播。

第一期沙龙活动我们邀请了三位嘉宾:谢益辉(RStudio软件工程师)谈谈有关R Markdown的一些新进展和小功能;阎军(康涅狄格大学统计系副教授)八卦一下统计学家中的音乐家;冷静(密歇根大学学生,COS沙龙主持人)分享一下来美国一年对计算机系和统计系的不同文化的感受。

Max Kuhn, author of Applied Predictive Modeling (http://appliedpredictivemodeling.com/) and caret package, will talk about the practice of predictive modeling. The practice of predictive modeling defines the process of developing a model in a way that we can understand and quantify the model's prediction accuracy on future data.
