Fitria Wulandari Ramlan
I'm a PhD Candidate in Artificial Intelligence at the School of Computer Science, University of Galway, Ireland. Under the supervision of Dr. James McDermott and Dr. Colm O'Riordan, I specialise in interpretable machine learning through symbolic regression and genetic programming, developing transparent mathematical models for regression that balance accuracy with interpretability. My research covers synthetic data generation for limited and extrapolation settings, model selection criteria for symbolic regression, hybrid penalties for extrapolation instability and input sensitivity, and applications to climate-energy surrogate modelling.

CurrentDeveloped a knowledge distillation framework using neural network and random forest teachers to generate KDE-targeted synthetic data, improving symbolic regression performance under limited and unevenly distributed training data. Showed that KDE-based region identification outperforms geometric bounding box methods for extrapolation, with statistically significant improvements across six benchmark datasets. Conducted the first systematic comparison of five model selection criteria (MSE, AIC, BIC, MDL, PSM) for symbolic regression across 20 PMLB benchmark datasets, using Spearman rank correlation to measure alignment with test performance. Developed hybrid model selection criteria that extend standard metrics with extrapolation divergence and input sensitivity penalties; identified two practically useful configurations (MVP-BIC and MVP-MDL; MVP: Multiple Variable Perturbation) that consistently improve extrapolation model selection. Validated the hybrid framework on a real-world energy system surrogate modelling problem, achieving approximately 98% improvement in test MSE without domain-specific tuning. Achieved peer-reviewed publications in top venues including EuroGP, GECCO, and ECTA. Teaching Assistant for undergraduate and postgraduate modules for two years; did a weekly journal club among PhD researchers in the same field throughout the PhD.
