# Simple applications of Python machine learning

#### Introduction
The  **sklearn**  machine learning repository is used for classification and prediction. The repository proposes two prediction algorithms and two classification algorithms, using  **linear regression and support vector machines (SVM)**  for prediction and  **K-Means clustering and plain Bayesian**  for classification.

#### Project structure
The modules to be used ： **sklearn、pandas、numpy、matplotlib、seaborn** 。

#### Instructions for use
sklearn Chinese Community：https://scikit-learn.org.cn/  
Boston House Data：http://lib.stat.cmu.edu/datasets/boston  
The data set used to ： **1、Boston House Data（Predict）；2、Iris data set（Classification）。**

#### Introduction to the Boston House Price Dataset  
| Indicators  | Explanation  |
|---|---|
| CRIM  |    per capita crime rate by town |
| ZN  |  proportion of residential land zoned for lots over 25,000 sq.ft.  |
| INDUS  |   proportion of non-retail business acres per town  |
|  CHAS |  Charles River dummy variable (= 1 if tract bounds river; 0 otherwise)   |
| NOX  |  nitric oxides concentration (parts per 10 million)  |
| RM  |  average number of rooms per dwelling   |
| AGE  |  proportion of owner-occupied units built prior to 1940   |
|  DIS |  weighted distances to five Boston employment centres   |
|  RAD |  index of accessibility to radial highways |
|  TAX | full-value property-tax rate per $10,000   |
|  PTRATIO |  pupil-teacher ratio by town   |
|  B | 1000($B_k$−0.63)$^2$ where $B_k$ is the proportion of blacks by town |
|  LSTAT |% lower status of the population   |
|  MEDV | Median value of owner-occupied homes in $1000's   |

#### Introduction to the Iris data set  
iris_training.csv，Training data set，120 sample data；iris_test.csv，Test data set，30 sample data。  
| Indicators |Explanation  |
|---|---|
| Sepal Length  |  Sepal Length |
| Sepal Width |  Sepal Width   |
| Petal Length | Petal Length  |
|  Petal Width | Petal Width     |
| 0  | Setosa  |
| 1  | Versicolor|
|2 | Virginical    |
