Selected Projects

Research Projects - Visual Information Processing

Psychometrics | Bayesian Models | Mathematical Approaches

To gain insights how visual perception works as an “unconscious inference” and how our brain uses computational representations to process visual information, I measure visual percepts of humans and reveal the underlying models.

Daily progress in my PhD journey

Data Visualization | Interactive Dashboard

Approaching the end of my PhD, I set up a daily standup meeting and recorded my daily progress in a spreadsheet. This app is to visualize the data and help me to track my progress.

BCG Virtual Experience Program - Customer Churn Prediction

Business Understanding and Strategies | Classification

In this open-access BCG Virtual Experience Program with Forage, I built a predictive model that can identify customers at high risk of churn for a utility company.

Diabetes health indicator

Classification | Model Tuning

Early diagnosis of diabetes is important to prevent the onset of complications. From survey data, I found health indicators that are most associated with diabetes.

Spotify music recommender

Recommender System | Dimensionality Reduction | Streamlit App

I used Spotify’s audio features to build a music recommender system. I further developed a web app in which the recommender system can be customized by selecting the features.

Forest Cover Type - Compare Classification Algorithms

Classification | Model Tuning

In this project, I predicted the forest cover type (the predominant kind of tree cover) from strictly cartographic variables (as opposed to remotely sensed data). I compared different classification models and applied hyperparameter tuning to the best model.

Catch the CATs - Explore Feature Engineering

Exploratory Data Analysis | Feature Engineering

In this project, I performed feature engineering on various features, including binary features, low- and high-cardinality nominal features, low- and high-cardinality ordinal features, and (potentially) cyclical features.
