Project: Guangzhou Construction Projects Contract Online Filing S ystem (2 Phase)

Contract parties fill the contracts forms online, submit to audit staff to review and confirm the contracts. Audit staff has rights

to return the review requirement from parties if the contract is not qualified.

I designed test cases using test methodologies, implemented the cases, adjusted the cases and methods to widely cover all

functions and flaws, and communicated with project manager and developers to check possible reasons for flaws.

Relationship between LinkedIn use and job hunting success rate 09/2013- 12/2013

Course project for Social Computing

Study relationship between LinkedIn profile features and users job hunting outcomes or skills ’ endorsement

Conduct survey to collect respondents’ demographic information as well as LinkedIn using behavior information.

Collecting social data, and implement linear regression and other data mining algorithms for prediction.

One of our outcomes by now was that the number of groups users joined has posi tive influence on their skills endorsement

count. More relationships have been revealed by our study.

Method used: Linear Regression, Snow Ball sampling.

Course project for Data Mining

A closed competition from Kaggle.com to predict popularity of Xbox games based on users’ search queries and behavior.

Find top five popular Xbox games after analysis data.

Using data mining and machine learning algorithm to analysis data, which included 42365 samples.

Feature selection, texting mining and comparing different algorithms based on their attributes were main tasks.

Method used: Data Mining, Machine Learning Algorithm: Logistic Regression, SVM, Naï Bayes.

ve

Language used: R, Python.

Predict survival on the Titanic 01/2013- 05/2013

Course project for Data Analyst.

Using structured data including passenger information, tickets fare and socio-economic status to predict what kinds of

passenger have higher possibility to survive from Titanic disaster.

1

We tried different methods such as SVM, Naï Bayes, and Random Tree to build the prediction model. Disctretized the ages

ve

and replaced the missing value with the average age. Used leave one out cross validation to text our models.

Made assumption about what were the crucial features that keep passenger alive then proved them.

Got 81% accuracy on Kaggle evaluation and ranked 23 out of 2547 teams at that time.

Software used: GeNie, Excel, Weka

Geographical Navigation System Based on Air Pollution Exposure 01/2013- 05/2013

Compute air pollution exposure weight of road segment and choose optimal route option s for users, based on EPA database

and Pennsylvania road network.

Using distribution system and sending dataset and computation modules to open source cloud to shorten computation time of

road segments.

Broaden road map from PA to the United State.

Software used: ArcGIS, MySQL
