Hi all,
I found a job position which demands applicants to master the following skills:
At Least 3 Years of experience and knowledge of:
- Java
- Scala
- Hadoop
- Online Advertising / Ad Tech experience

Who can tell me what machine learning is?
Thanks a lot in advance.

发现好像还是没回答，什么是机器学习。哈哈哈，具体定义，请google，baidu，教科书。

1.先回答你的问题，What is machine learning？首先这已是一门学科，属于人工智能一个重要部分。 2..这门学科（机器学习）是为了解决什么问题呢？让机器（多指计算机）能和人一样学习。 3.这门的具体应用在哪些领域计算机视觉（人脸识别，图片搜索等）；自然语言处理（语音识别（微软的Cortana），机器翻译等）；社交网络分析（热点发现，用户画像等）；推荐（音乐推荐，网购产品推荐，广告推荐）；题主的招聘信息，应该是一家要用机器学习来做广告推荐吧。 4.再来回答下，机器学习，数据挖掘（有人提到）等间的关系？看这篇就行： http://www.open-open.com/lib/view/open1420615208000.html 5.最后说下学习该课程建议：你可以学习这个视频，如果记得大学的高数和线代，概率，你会发现其实入门时简单的。下面是coursera里Andrew Ng的课程，浅显易懂。 https://www.coursera.org/learn/machine-learning

It's about Artificial Neural Network, Fuzzy Logic, Genetic algorithm and other kinds of algorithms. The classic use is to predict house price or something like it.

机器学习普通程序员用不到，几个应用：微软Cortana、Kinect人体识别追踪、Google Brain。。。

Machine learning is a subfield of computer science (CS) and artificial intelligence (AI) that deals with the construction and study of systems that can learn from data, rather than follow only explicitly programmed instructions. Besides CS and AI, it has strong ties to statistics and optimization, which deliver both methods and theory to the field. Machine learning is employed in a range of computing tasks where designing and programming explicit rule-based algorithms is infeasible for a variety of reasons. Example applications include spam filtering, optical character recognition (OCR),[1] search engines and computer vision. Machine is sometimes conflated with, and sometimes distinguished from data mining and pattern recognition.[citation needed] Machine learning tasks can be of several forms. In supervised learning, the computer is presented with example inputs and their desired outputs, given by a "teacher", and the goal is to learn a general rule that maps inputs to outputs. Spam filtering is an example of supervised learning, in particular classification, where the learning algorithm is presented with email (or other) messages labeled beforehand as "spam" or "not spam", to produce a computer program that labels unseen messages as either spam or not.

[quote=引用 22 楼 bfdeh 的回复:] I think it's some kind of human intelligent.

Do you mean it is a branch of artificial intelligence? Would you pls.explain it exactly and specifically to make it easy to understand? Thanks a lot in advance.[/quote] It's better with an example to illustrate.

[quote=引用 16 楼 huangjianwu 的回复:] 机器学习这门学问，应该是“人工智能”、“数据挖掘”方面的意思！

Many of programmers seem not to be familiar with this.[/quote] Yes, it's a professional knowledge so that programmers must spend a lot of time to understand it. 不装X，在水区，还是说母语吧！
