How to make the search engine have "life"?

In many people's opinion, search engines are just a search tool, just like other cold tech products. In fact, search engines are becoming a smart helper that everyone relies on. After having the ability to perceive the environment and learn from oneself, it will continuously transform the information into knowledge as the years go by, and then the knowledge will be precipitated into wisdom and be endowed with "life" value.

Online Learning, let search Engine "live"

Online Learning (on-line learning) is the key technology to make search engines "live", which makes search engines more powerful and more intelligent.

Theoretically speaking, the more a user uses a search engine, the more the search engine understands the user and the overall heat change, and the higher the recommended precision. The process of learning is to improve the accuracy of the algorithm according to the user characteristics. Before the online learning technology, search engine learning is done off-line, timed data model and sorting and recommendation algorithm update, but will not do after each user feedback update algorithm. Online learning makes "learning" more time-sensitive, granular granularity to each user. It can be at any time according to the user's download, click, stay time, mouse move these behaviors to understand the user and then dynamically adjust the sorting and recommendation algorithm, to users want.

On the technical online learning only need to compute the current user-related data, the incremental learning method saves computational resources while enhancing timeliness, as it can be predicted, recommended, and sorted while learning, which can be done by dynamically adjusting the recommendations to ensure the recommended results.

On the basis of this rapid iteration, Online learning can take more flexible strategies than off-line prediction, such as bandit strategy, it can reduce the redundancy of information, alleviate the Matthew effect, give more and more equal opportunities for resources, and can say that a kind of "blossom" state is formed, Quickly locate quality resources in a short period of time.

Online Learning or will usher in large-scale applications

Search engine results in Baidu, right bosom, app assistant recommended, multimedia search results, online learning system has been large-scale applications, related tests show that online learning can significantly increase the recommended click-through and user satisfaction. Now you search the right side of the "bunk bed" will not only appear related results, but based on the previous user search for similar keywords after the feedback, recommended small huxing decoration and other services.

Online learning on-line machine learning, the industry only Baidu has been large-scale commercial applications. Yahoo and Google have tried, but focused on experiments, research, or paper. Online leaning technology and Baidu is deep learning, Baidu brain and large data business has countless links, the next will be greater promotion and application opportunities, it is said that Baidu has been in the relevant technology has been applied for patents.

Like a child in the early days of saying, writing, walking all need to have adult deliberate training, this time it does not have "online learning" ability, but "supervised learning"; At a certain stage it can acquire some skills based on environmental feedback and personal experience, such as self-study bicycles during falling and cycling. After drinking water a few times the natural acquisition of swimming technology, this is the "online learning" mode. It can be said that the human brain itself is a system based on feedback online learning, online-learning is the human brain to receive the environment and the external "feedback" to enable people to constantly adjust their behavior of the process, this learning mechanism is the human progress and self-development of the source of power.

Online Learning Let search engines have life

This year, Robin Li revealed that the intelligence of the "Baidu Brain" is nearly 3 years old, and we do not know what the project actually does, and no technology media can go into the project to get a thorough understanding of it. Baidu introduced only a few figures: the use of computer technology to simulate the human brain. Baidu Brain also appeared in the world's first big data engine Baidu launched, the role of Baidu's brain is to enable large data engines in data mining based on the formation of "How to mining data" learning ability.

Now it seems that all technology is interconnected, Baidu's brain and online learning similarities are to let search engine "alive", with learning ability and intelligence level, eventually more and more intelligent.

In recent years, more and more technology giants have begun to pay attention to the harmonious coexistence of science and technology. Apple let technology and humanities and art more closely combined, wearable equipment so that technology wear or implanted in the human hidden existence, nest let science and technology have a sense of environment and self-learning ability, Baidu is to make search engines more intelligent, understanding people, Dialogue with human nature. All of these technologies will be integrated in the future: mobile phones, smart hardware, Internet services, ubiquitous technology that ultimately makes people feel that technology is not there, and that technology and the world are seamless and blended.
