Personalized event recommendation in Tickets 09/2019-12/2019 s Implemented a web Application for users to search activity and set favorite, and in the backend based on those favorite, used content-based recommendation algorithms based on user’s location, search history and favorite records to realize personalized event recommendation. s In the front-end, using HTML, CSS, JavaScript and AJAX to design the web external. Created three servlets, SearchItems, SetFavorite and Recommendation with RESTful APIs to handle HTTP requests and responses and deployed on Tomcat in JavaEE platform.

s Created database by using MAMP and connected MySQL by JDBC to store business data that filtrated from Ticketmaster API and migrated to MongoDB for better scalability. Used builder pattern to construct item class with many parameters. Implemented authorization for users to log in so that the session can maintain the status. Mathematical Pattern Recognition 03/2019-05/2019

s Applied one-hot encoding to deal with the categorical features. Used KNN to calculate means to institute the missing data. Provided PCA to extract feature in higher variance and adjust dimensionality. Fulfilled standard normalization to implement the standardization of data processing.

s Utilized cross validation to train datasets, select and attain the pioneer parameters of models. Chose parameters separately and plotted graph to visualize the tendency to narrow down and result in the best value for this model. s Trained perceptron, KNeighborsClassifier, support vector machine (SVM), bayes classification and achieved the highest evaluation as the final test model based on accuracy score, and f1-score evaluation. Android App: Assist blind people accomplishing daily reading tasks independently 07/2019-09/2019 s Implemented an Android Camera App as client side. Sent images from Android devices to Google OCR engine for recognition and results read back to users.
