discriminant models (discriminative model)The generation method is obtained by the data Learning Joint probability distribution P (x, y) and then the conditional probability distribution P (y| X) as the predictive model, the model is generated :
P (Y |X )= P(X,Y)p ( X )
This method is called a build method , which represents the generation relationship of output y produced by a given input x. such as: Naive Bayesian and Hidden M

Azure Machine Learning ("AML") is a Web-based computer learning service that Microsoft has launched on its public cloud azure, a branch of AI that uses algorithms to make computers recognize a large number of mobile datasets. This approach is able to predict future events and behaviors through historical data, which is significantly better than traditional forms

. Random Forest
Random forest is a proper noun for the overall decision tree. In the stochastic forest algorithm, we have a series of decision trees (hence the name "forest"). In order to classify a new object according to its attributes, each decision tree has a classification called the decision tree "vote" to the category. The forest chose to get the highest number of votes in the forest (in all trees).
Each tree is cultivated like this:
If the case number of the training set is N, the sample

The final predictive function can be used in two ways for classification and regression problems:

We can observe the sparse of a logical model, or train a random forest to select the best features and then use them on other machine learning models. Remember to keep a small number of estimator and minimize the parameters so that you don't over-fit.The selection of features can also be a

Dimensionality Reduction Method
Like the clustering method, the Dimensionality Reduction Method tries to use the internal structure of the data to summarize or describe the data. The difference is that it uses less information in an unsupervised manner. This is helpful for visualizing high-dimensional data or simplifying data for subsequent supervised learning.
