Machine Learning Course Projects

Age Recognition | Data-Driven Algorithms, University of Houston
I conducted age recognition problem as my final project during the Pattern Recognition course I completed at the University of Houston. I transformed 30k+ of face images from Kaggle into 128 measurements using OpenFace. Then I implemented the PCA analysis and ML algorithms such as SVM, Random Forest to solve the age recognition problem. Repo.
Financial Hedging | Math-to-Industry Boot Camp, Securian Financial
We worked in a team researching solutions for reducing the computational cost of the estimation of the Greek variables on the options market. My main contribution was to test performance of quadratic interpolation as a proxy model for the Black-Scholes model for Delta and Rho variables producing 3−5% relative error of approximation. Repo.
Match Prediction | Statistical Data Analysis, Wayne State University
As part of the Statistical Data Analysis course at Wayne State University, I conducted a final project focused on match prediction problem. I have collected 5k+ tennis match data from internet websites using parsing Python packages. Then I implemented ML algorithms such as KNN, QDA, LDA, Ridge&Lasso methods producing 89% prediction with KNN. Repo.
