代做SVC留学生作业、代写Python编程作业、代做Python作业、代写algorithm作业

日期：2018-12-02 10:26

This project is to be done individually. All the coding involves in this project must be in Python. You may only use techniques/algorithms covered in this class. However, you are allowed to use parameters, attributes, etc. that are not covered in this class as long as they belong to the techniques/algorithms covered in the class. For example, Support Vector Classification is the algorithm covered in the class but kernel=sigmoid is the parameter that is not covered in the class. You are allowed to use kernel=sigmoid with SVC. Meanwhile, genetic algorithm is the algorithm that is not covered in the class, so you are not allowed to use genetic algorithm in this project.

Your task in this assignment is to:

1.Provide summary statistics along with visualizations of these summary statistics for the variables that are interesting/relevant to your analyses.

2.Develop a regression model (i.e., a supervised-learning model where the target variable is a continuous variable) to predict the value of the variable “pledged.” After you obtain the final model, explain the model and justify the predictors you include/exclude.

3.Develop a classification model (i.e., a supervised-learning model where the target variable is a categorical variable) to predict whether the variable “state” will take the value “successful” or “failure.” After you obtain the final model, explain the model and justify the predictors you include/exclude.

4.Develop a cluster model (i.e., an unsupervised-learning model which can group observations together) to group projects together. After you obtain the final clusters, explain the characteristics that you observe in each cluster. Note that you will be graded based on the performance of the model and the insights you obtain from the clustering task. For example, if your model generates two clusters with a high cluster separation and low cluster cohesion but one cluster essentially represents successful projects while another cluster essentially represents failed projects, then the insights gained are severely limited.

For all tasks, you will be graded based on both the performance of the model and the explanations/justifications you provide. You also need to clearly articulate how realistic or useful your model would be in a business context.

There are two deliverables for this assignment:

1)Summary Report

The report must be submitted in pdf format.

The report must not exceed 5 double-spaced pages, including everything. Page margins must measure 1” around. Please use a 12-point Times New Roman font.

Name the file as follows: “Lastname_Firstname_IndividualProject”

The report must contain:

oThe summary statistics

oThe explanations/justifications of each model along with the results. You may submit only one model per task.

The report is due by Tuesday, December 3 at 11:59pm.

2)Python Code

Along with the report, please also submit Python code that you use to develop your report. The code should be complete with informative comments and able to run fully without any errors or modifications (besides the file path).
