Projects:-----------------------------------------------------------------------------------------------"Twitter Real-time Data Processing" in Big Data Architecture -----------------------------------------------------------------------------------------------Project Github: https://github.com/CUBigDataClass/tweet_spread - Used Kafka, Storm, and Cassandra to build an infrastructure on AWS which is capable of queueing, analyzing and storing streaming data. Twitter streaming api is used as the data source.- Set up a website with Django and d3.js, which perform real time updating and loading the streaming data.-----------------------------------------------------------------------------------------------"Tetris Reinforcement Learning" in Machine Learning -----------------------------------------------------------------------------------------------Project Github: https://github.com/Azurisky/ML_Final_project - Developed a Python-based reinforcement learning agent to play Tetris and earn as many points as it can. It can easily beat human in the same time period after training.- Implement Q-learning algorithm by Q-table and build a Neural Network model to improve the learning speed.-----------------------------------------------------------------------------------------------"Youbike station analysis" in Data Mining-----------------------------------------------------------------------------------------------Project Github: https://github.com/Azurisky/Youbike- Processed, analyzed and visualized Youbike dataset by using time and weather as features. - Builded a linear regression model which had about 65% accuracy of prediction for lending frequency.

- Used frequent item set and word embedding to analyze source code from Github. Source codes are split into modules with independent functions by the proposed method, which leads to more readability.- Implemented an interactive interface and dialog tutorials by iPython notebook for beginners to learn coding easily.

Cn

- Set up a Kafka service on Flask server, separately dealing with the streaming input from offline and online API.- Used Kafka, Spark Streaming, JanusGraph and Hbase in Scala system to build a graph-based network, increasing the computation efficiency for relationship of large amount of people.

- Constructed an end-to-end approach for outlier adjustment. Imputed the raw data with KNN and then detected the outliers by robust covariance estimate. After that, adjusted outliers and built the mean variance optimal portfolio to assess the performance, which gives 9% higher return comparing to the existing model.- Used CNN to implement deep reinforcement learning for analyzing stock’s tick data. On average, the new model gained 14% more profit comparing to widely adopted approaches, including Uniform Constant Rebalanced Portfolios.

- Implemented Python-based crawler program to get data from websites of different travel agents, and further analyzed the ideal travel group for customers by K-modes Algorithm. - Developed company websites by php/Javascript and a line chat bot by Python.
