About Me
I am Rizal Fathony [full name: Rizal Zaini Ahmad Fathony], a final-year PhD student at the Department of Computer Science, University of Illinois at Chicago. I work with my advisor Prof. Brian Ziebart in statistical machine learning theory and applications. Before attending PhD program at UIC, I completed Bachelor of Applied Science degree in Statistical Computing from the Institute of Statistics, Jakarta, Indonesia and Master of Science in Computer Science from the University of Illinois at Chicago.
Research
Performance-Aligned Learning Algorithms with Statistical Guarantees
My research focuses on designing robust adversarial learning algorithms for various tasks that simultaneously align with the learning objective by incorporating the performance metrics or loss functions into the learning process and provide the statistical guarantee of Fisher consistency.
In my previous and ongoing works, I design robust adversarial learning algorithms for the following tasks:
- Multiclass classification
- Ordinal classification with absolute loss and squared loss
- Classification with abstention
- Conditional graphical models (chain, tree, and low-treewidth graph structures)
- Bipartite matching in graphs
- Fairness in machine learning
Research interest:
Consistent learning algorithms | Fairness in machine learning |
Multivariate metrics | Multi-task learning |
Robust adversarial learning | Deep learning |
Structured prediction | Causal machine learning |
Approximate inference | Bayesian machine learning |
Multivariate metrics | Multi-modal regression |
