Last week at the China R Language Conference in Beijing, I shared with you how to visualize the interactive data of R language. The field students are interested in this piece of content, so today put some common interactive visual R package out to share with you.Rcharts PackageSpeaking of the interaction package of the R language, the first thing to think about is the Rcharts package. The package generates a D3-based web interface directly in R.Installation of the Rcharts packageRequire (Devtoo
Summary: What is data mining. What is machine learning. And how to do python data preprocessing. This article will lead us to understand data mining and machine learning technology, through the Taobao commodity case data preprocessing combat, through the iris case introduced a variety of classification algorithms.

This article mainly introduces the use of TensorFlow implementation of multi-class support Vector machine example code, now share to everyone, but also to make a reference. Come and see it together.
This article will detail a multi-class support Vector machine classifier training iris data set to classify three flowers.
The SVM algorithm was originally designed for the two-value classification problem, but it can also be used to make multi-class clas
SVM (Support vector Machine) refers to support vector machines, which is a common discriminant method. In the field of machine learning, it is a supervised learning model, which is usually used for pattern recognition, classification and regression analysis.
MATLAB has Lin Zhiren written LIBSVM toolkit can be well carried out SVM training. Python We have the Sklearn Toolkit for Machine learning algorithm training, Scikit-learn Library has implemented all the basic machine learning algorithms.

One; prefaceThe people who have learned the TCP/IP protocol have a feeling, this thing is too abstract, there is no data instance, after reading soon forget. This article will introduce an intuitive learning method, using the Protocol analysis tool to learn TCP/IP, in the process of learning to visually see the specific transmission process of data.For beginners to understand more easily, this article will build a simplest network environment, does not include subnets.Second, the test environmen

height of the layout viewport is equal to the size of any content that can be displayed on the screen in the minimized mode. These dimensions remain the same when the user zooms in.Layout viewport width is always the Same. If you rotate your phone, visual viewport changes, but the browser fits the new orientation with a slight magnification, so the layout viewport is as wide as the visual Viewport.This has an impact on the height of the layout viewport, which is now smaller than portrait mode (

The Adabag packages in R have functions that implement the classification modeling of bagging and adaboost (in addition, the bagging () function in the ipred package can implement bagging regression). The first problem is to use adabag package to achieve bagging and adaboost modeling, and select the optimal model based on the predicted results.A) to describe both approaches, first build the model with all of the data:Use boosting () (the original adaboost.
