Recommender system for amazon products 01/2019 ~ 05/2019

used collaborative filtering algorithms, deep learning and graph-based methods to build a recommender system for amazon products.

a matrix factorization method named singular value decomposition and stochastic gradient descent are applied.

Restricted Boltzmann Machine is applied to recommends items by trying to find users that are similar to each other based on their item ratings.

personalized PageRank algorithm is applied to calculate the similarity between products. Web-based Stock Forecaster 01/2019 ~ 05/2019

used Angular.js front-end framework, flask back-end framework and MongoDB database to develop dynamic and interactive website that ensured high traffic, page views and user experience.

user can get the predicted result of stock in the short and long term according to the indicators and their choices.

Machine learning methods, such as Bayesian Curve Fitting, Artificial Neural Network and Support Vector Machine, are applied to the prediction.

Credit scoring system based on logistics regression 01/2016 ~ 05/2016

Data preprocessing include data cleaning, missing value and outlier processing.

Statistical method is used to explore the data distribution and select variable.

Model development includes variable segmentation, variable (WOE)weight of evidence transformation and logistic regression estimation.

Model evaluation is to evaluate the distinguishing ability, predictive ability and stability of the model.

Built a credit scoring system through using logistics regression to fit the data and then got the credit score based on coefficients of logistic regression and WOE, in the end, evaluated the result through ROC curve. Competition
