Hi, I'm Pradhyumnaa! I build complete machine-learning workflows — from data preparation to model development and performance evaluation. I've worked across NLP, time-series forecasting, physiological sensor data, and large tabular datasets.

Featured Projects


Higgs Boson Identification

Residual SwiGLU Deep MLP for Higgs boson signal identification, achieving 88.52% ROC-AUC, 89.50% PR-AUC, and 79.99% accuracy on the full 11M-row HIGGS dataset, after benchmarking LightGBM, XGBoost, autoencoder-enhanced trees, and physics-engineered feature baselines.


Surrogate Modelling for Large-Scale Wave Energy Farms

Physics-informed LightGBM surrogates predict the total absorbed power of large WEC arrays from their spatial layouts, reaching 0.9969 R² with 0.041% relative MAE on 49-WEC Sydney configurations. Across all four large-scale datasets (49- and 100-WEC layouts for Perth and Sydney), relative MAE remains below 0.23%.


Intent Classification & Out-of-Scope Detection on CLINC150

BERT-based 150-class intent classifier achieving 96.31% accuracy, supported by a full few-shot evaluation pipeline (10–50 samples per intent) using deduplicated, leakage-free splits. The project also focuses on a complete Out-of-Scope detection system built with Outlier Exposure, energy-based scoring, and Mahalanobis distance—achieving 0.98 AUROC in distinguishing in-domain from unseen queries.


Spoken-Language Intent Classification and Slot Filling

BERT-based 7-class intent classifier achieving 98.56% accuracy, and a DistilBERT slot-filling model reaching 94.5% entity-level F1 on the SNIPS 2018 dataset. Few-shot experiments reached 97.84% accuracy with only 70 samples per intent. The full pipeline includes preprocessing, leakage-safe splits, tokenization, training, and evaluation.




Additional Projects


Lightweight phishing URL detection using pre-fetch features only, with incremental learners reaching 96.19% accuracy.


95.3% accuracy on the 3-class fetal health (NSP) task, and 91.7% accuracy on the 10-class fetal heart rate (FHR) classification problem.


88.29% AUC and 80.88% accuracy for gallstone detection using 10-fold cross-validation.
