Web pages is also occupied by those posts that do not have much nutrition. I sincerely hope that the atmosphere in China will be more intense. Game Players really like to make games, and Data Mining players really like to dig Data, not just for mixed meals, in this way, it makes sense to talk more than other people. In Chinese articles, there are too few things about technology in a down-to-earth manner. To change this situation, start with me.

Machines (SVM), referred to as the SV Machine (the general abbreviation in the paper). It is a supervised learning method, which is widely used in statistical classification and regression analysis. Support Vector machines map vectors to a higher dimensional space, where a maximum interval of hyperspace is established in this space. On both sides of the super plane that separates the data, there are two su
Based on the literal Relevance Model of Baidu keyword search recommendation tool, this article introduces the specific design and implementation of a machine learning task. Including target setting, training data preparation, feature selection and filtering, and model training and optimization. This model can be extended to Semantic Relevance models, and the design and implementation of Search Engine releva

Now machine learning algorithms in classification, regression, data mining and other issues on the use of a very broad, for beginners, may be heard ' algorithm ' or other exclusive nouns feel inscrutable, so many people are deterred, which makes many people in dealing with a lot of problems lost a very useful tool.

With the continuous development of machine learning, artificial intelligence has launched a new upsurge. The artificial intelligence revival, the biggest characteristic is the AI can walk into the industry real application scene, with the business model close union, starts to play the real value in the industrial field.
In the industry's real application, how to mining
1. Background
Decision Book algorithm is a kind of classification algorithm approximating discrete numbers, which is simpler and more accurate. International authoritative academic organization, Data Mining International conference ICDM (the IEEE International Conference on Data Mining) in December 2006, selected the ten classical algorithms in the field of mining
feature values. However, only by understanding how to derive them can we have a deeper understanding of the meaning. This article requires readers to have some basic linear algebra basics, such as the concept of feature values, feature vectors, spatial projection, and dot multiplication. I will try to make it easier and clearer about other formulas.

The full name of LDA is linear discriminant analysis (linear discriminant analysis ),Is a supervised learning.Some materials are also known

guesses, and certainly not very accurate at first. But based on this speculation, it can be calculated that each person is more likely to be male or female distribution. For example, a person's height is 1.75 meters, obviously it is more likely to belong to the male height of this distribution. Accordingly, we have a attribution for each piece of data. Then, according to the maximum likelihood method, the parameters of male height normal distribution are re-estimated by these several data which

COMMON Pitfalls in machine learningJanuary 6, DN 3 COMMENTS Over the past few years I has worked on numerous different machine learning problems. Along the the I have fallen foul of many sometimes subtle and sometimes is subtle pitfalls when building models. Falling into these pitfalls would often mean when you think you had a great model, actually in Real-life
addition, there are many tools that allow users to import content to mahout. Among them, the most exciting thing is not tangible, but the growth of the mahout community. The Community has attracted a number of objective contributors and users. During the development process of any open-source project, the initial stage is often miserable, and there are usually only one or two people doing their work. Once one of them leaves, it may even slow down the development speed, the entire project may cr
