Google stock price prediction (RNN, LSTM)

• Predict 1 month Google stock price based on past 5 years stock price data downloaded from Yahoo finance. Built a recurrent neural network to predict Google stock price trends in one month based on past 5 years of historical stock price data. Designed data structure to fit LSTM model. Visualize the result using matplotlib.

Pictures of Animal species recognition (CNN) (CNN)

• Predict animal species based on 10k labelled pictures. Built a convolutional neural network which is able to recognize picture contents of different species of animals based on 10K pictures source data.

Mandarin hotel/restaurant booking website (ASP.NET-MVC, C#, SQL Server, JavaScript)

• Responsible for parts of the websites for restaurant in a hotel. Specifically, implemented dish menu ordering and news updating function within control, view and model.
• Coding the back-end client side using C# programming language, interacting with database using SQL language.

Customers reviews analysis (NLP, Naive Bayes) (NLP, Naive Bayes)

• Predicted the restaurant customers’ positive or negative attitudes based on 1k labelled customer reviews. Use nlkt library to preprocess data, use sklearn.countvectorizer to build a Bag of Words model and eventually implements the prediction with Naive Bayes.

Android card game 2048 (Android Studio, Java)

• Solely developed android game on windows platform using android studio.
• Designed a 4x4 grid layout of game card. Implemented score merging algorithm by listening to finger motion, calculated the scores and implemented the game termination condition, all using Java programming language.

Netflix Movie Recommender System.(MapReduce, Hadoop, Linux Ubuntu, Java)

• Implemented movie recommendation system based on customer watching history.
• Built a Movie score matrix out of datasets based on collaborative filtering, built the movie co-occurrence matrix, merged it with movie score matrix to get a recommended list.
• Connected all the processes using MapReduce jobs and implemented MapReduce Matrix multiplication
