  Colorado Hydrocarbon Production & Socio-economics

  The oilonomics (Oil + socio-economics) is a web application for analyzing impact of hydrocarbon production on socio-economics with Colorado as the study area. Extensive analyses were done through regression, correlation and forecasted how each socio-economic factors will behave accordingly to hydrocarbon production.

  Deep Learning for CheXpert

  With utilization of DenseNet121 and PyTorch, a new and existing machine learning models are evaluated and created. Given chest diseases (labels) as predictors, numerous features from clinical data, in conjunction with X-ray images, the model is evaluated with over 85% AUC.

  Predicting Flight Delays

  Three multiclass-multiootput probabilistic models (Random Forest, XGBoosting, KNN) are discussed and evaluated with given METAR-ASPM data provided for major airports in the United States. The outputs are generated as an average of an airport’s probability of a flight to be delayed. Extensive parameter tunings are involved via grid-searching to optimize models and increase accuracy.

  Raven's Progressive Matrices Solver

  Raven’s Progressive Matrices (RPM) solver is an Artificial Intelligent Agent which attempts to solve for 2 x 2 and 3 x 3 RPM problems. Utilizing multiple image processing techniques and transformations via Python’s Pillow and OpenCV, the agent is designed to optimize its workflow in search for best matching choice among 6 (2 x 2) or 8 (3 x 3) choices. The accuracy of the performance lies at around 80% with efficiency at 10 seconds for 20 questions.
