Although the "editor's note" has been available for 9 years, the popularity of Mongodb,hamsterdb is still lacking, and it has been rated as a Non-mainstream database. Hamsterdb is an open source key value type database. However, unlike other Nosql,hamsterdb, which are single-threaded and not distributed, they are designed to be more like a column store database, while also supporting acid transactions at the Read-committed isolation level. Then compare Leveldb,hamsterdb will have any advantage, here we go ...

Machine learning is a science of artificial intelligence that can be studied by computer algorithms that are automatically improved by experience. Machine learning is a multidisciplinary field that involves computers, informatics, mathematics, statistics, neuroscience, and more.

Machine learning engineers are part of the team that develops products and builds algorithms and ensures that they work reliably, quickly, and on a scale.

Shrinking to achieve, in Alibaba's 2017 double 11 singles day, our domestic trading unit used cloud resources to sharpen and expand at the peak, and after the spike, the expansion resources will be returned to the cloud, but in the actual operation, we really want What can we do to get the resources to the cloud when we need it, and go smoothly when we don't need it.

Artificial intelligence has entered everything – from autonomous cars to automatic emails to smart homes. You seem to get any merchandise (such as medical health, flight, travel, etc.) and make it smarter through the special application of artificial intelligence.

Today, technology with deep learning and machine learning is one of the trends in the tech world, and companies want to hire some programmers with a good background in machine learning. This article will introduce some of the most popular and powerful Java-based machine learning libraries, and I hope to help you.

Online education is in full swing, and traditional educational institutions are trying to cut through different paths, on the macro level, there are two schools: with internal incubation, external investment, such as the layout of pure online/mobile tools, refactoring learning methods; the other is to integrate offline content, teachers ' resources and improve the efficiency of operation management with O2O way. Different routes, reflecting the different thinking in the face of online education. The introduction of e-learning, the old personalized counseling institutions to learn large education is a typical case of the second school, recently in the Education Professional Media network held online activities, "they" on, learning the CEO jinxin with independent speech ...

"Editor's note" with the development of artificial intelligence technology, the major technology companies have increased their investment in deep learning, and as the National Science Foundation is the same, now, it through the funding of the United States University researchers, to promote the depth of learning algorithms on the FPGA and super computer running. Although it is only a trend that represents the depth of learning, but with the business operations of major technology companies and more in-depth study into the University Research Center and the National Laboratory, the development of in-depth learning to play a positive role in promoting. The following is the original: machine learning in the past few years ...

Introduction: It is well known that R is unparalleled in solving statistical problems. But R is slow at data speeds up to 2G, creating a solution that runs distributed algorithms in conjunction with Hadoop, but is there a team that uses solutions like python + Hadoop? R Such origins in the statistical computer package and Hadoop combination will not be a problem? The answer from the king of Frank: Because they do not understand the characteristics of R and Hadoop application scenarios, just ...
