a good effect, basically do not know what method of time can first try random forest.SVM (Support vector machine) The core idea of SVM is to find the interface between different categories, so that the two types of samples as far as possible on both sides of the surface, and the separation of the interface as much as possible. The earliest SVM was planar and limited in size. But using the kernel function (kernel functions), we can make the plane proj
Online looking for an article, for the entry stage or more appropriate, there is some knowledge before some contact, first understand, the specific contact will not be so abrupt.This paper divides machine learning algorithms into 4 categories according to learning methods: supervised
deduce it into a form that can be directed. (to say the last, I personally think not to remove | | w| |, is also the same can get the final correct classification of the super-plane, is directly using the distance as a loss function is also possible, may be the gradient is more complex, or the perception machine itself is to use the wrong classification points to distinguish, it is useless this loss function.
Python machine learning decision tree and python machine Decision Tree Decision tree (DTs) is an unsupervised learning method for classification and regression. Advantages: low computing complexity, easy to understand output results, insensitive to missing median values, and the ability to process irrelevant feature da

Transferred from: http://www.ctocio.com/hotnews/15919.htmlMachine learning is undoubtedly a hot topic in the field of current data analysis. Many people use machine learning algorithms more or less in their usual work. This article summarizes common machine
of a nonlinear function sigmoid, and the process of solving the parameters can be accomplished by the optimization algorithm. In the optimization algorithm, the gradient ascending algorithm is the most common one, and the gradient ascending algorithm can be simplified to the random gradient ascending algorithm.2.SVM (supported vector machines) Support vectors machine:Advantages : The generalization error rate is low, the calculation cost is small, the result is easy to explain. cons : Sensit

-party library, without organic integration, the corresponding learning costs will be higher. Python is faster than R. Python can directly deal with the data on the G, R No, r analysis data need to first through the database to transform big data into small data (through GroupBy) to the R for analysis, so R can not directly analyze the behavior of the list, can only analyze statistical results. Python's adv
generally large, so we only need to calculate a dimension, so that after the first convolution size is:200+2−52+1=99 \frac{200+2-5}{2}+1=99After the first pool size is:99+0−31+1=97 \frac{99+0-3}{1}+1=97The size after the second convolution is:97+2−31+1=97 \frac{97+2-3}{1}+1=97 The final result is 97. 3. Exercise 2 (SPSS basis) In the basic analysis module of SPSS, the function is "to reveal the relationship between data in the form of row and column list
a machine learning problem (such as a decision problem that needs to be modeled from data), think about what type of problem can be borrowed directly, or what the user or demand expects, and vice versa. ResourcesThere are few resources to list the problems of machine learning
Scikit-learn (formerly Scikits.learn) is a open source machine learning library for the Python programming language. It features various classification, regression and clustering algorithms including support vector machines, logistic regre Ssion, naive Bayes, random forests, gradient boosting, K-means and DBSCAN, and is designed-interoperate with the Py
-3PO, Terminator. There is also a concept of "weak AI" (narrow ai). In short, "weak AI" can accomplish some specific tasks like human beings, possibly better than humans, for example, Pinterest service uses AI to classify images, Facebook uses AI to identify faces, and this is "weak AI". The above example is a case of the actual use of "weak AI", which has embodied some of the characteristics of human intelligence. How to achieve. Where the intelligence comes from. With a question we understand
The last three weeks of Andrew Ng's machine learning were recently followed by the linear regression (Linear Regression) and logistic regression (logistic Regression) models in machines learning. Make a note here.Also recommended a statistical study of the book, "Statistical Learning method" Hangyuan Li, Book short, on

For example, in the recommendation system, after basic computing, the competition still fails to achieve good results, because data preprocessing is very important, whether in the competition or in the project, data preprocessing requires many machine learning algorithms.
