  • Specialization: supervised methods (decision tree, KNN, Ensemble methods, Naive Bayes and SVM) and unsupervised methods (PCA, Clustering, Text Mining and Analysis and Association Analysis)

As a Policy Analyst 📑

Project experience 💻

💡 Network Analysis of Twitter to Identify Opinion Leader, Emotion Cascade and Community Structure
  • Deployed K-core decomposition to examine the community structure, applied NLP including Name Entity Recognition, Sentimental Analysis and Topic Modelling on tweets to investigate the emotion cascade
💡 How Consensus can be Involved through Innovating Voting Mechanism?
  • Using PCA and UMAP to visualize the participants’ stance on a 2-dimensional map, uses Kmeans to cluster and classify group A and B, and uses centroid coords calculation to get the distance between two groups.
💡 Predicting Attitudes toward UBI in EU using Machine Learning Techniques
  • Built and trained Logistic Regression, DecisionTree, SVM, RandomForest, XGBoost and GBDT to identify 5 primary indicators and 35 secondary indicators the key influential factor on the attitude of EU citizen towards UBI
💡 Using DID to Evaluate the Impact of Intensive Case Management Services
  • Designed DID to construct quasi-experiment setting for causal inference to quantify the impacts
💡 Can Remittances Compensate for Parental Absence? Evaluated by the Psychological Well- being and Educational Outcome
  • Developed a multivariate model in STATA incorporating Difference-in-Difference and Propensity Score Matching
  • Estimated the indirect effects and direct impacts of remittances in the context of parental work-related migration on the well-being and academic achievements of left-behind children.
