Hate Speech Bias Mitigation with LLM Counterfactuals
Engineered LangChain pipeline with Llama-3.2-1B to generate 1,301 counterfactual samples, reducing demographic bias by 5.02% across 5 ML classifiers on 2K-sample Jigsaw dataset. Boosted model performance by 7.91% F1 score through synthetic data augmentation, validating fairness across gender, race, and religious identity dimensions. Built production pipeline with prompt templates achieving 7.7 prompts/sec batch processing and 90% sample validity post-filtering.
Brain-Computer Interface EEG Classification
Designed a Bidirectional GRU-CNN hybrid model to decode EEG signals for multi-class motor imagery tasks (left/right hand, feet, tongue). Achieved state-of-the-art performance on BCI Competition IV-2a dataset with 96.29% test accuracy with 22-channel EEG data through advanced signal preprocessing and frequency-domain feature extraction. Implemented end-to-end deep learning pipeline with TensorFlow incorporating sliding window segmentation, batch normalization, and regularization for robust temporal-spatial pattern recognition.
CryptoStats – Real-Time Cryptocurrency Widget
Developed a Plasma 6 desktop widget (Pling page) delivering live crypto prices via Coinbase API every 5 seconds. Built a zero-configuration RESTful backend with curl and a scalable QML front-end featuring dynamic color-coded indicators. Optimized for efficiency, seamless KDE integration, and production-grade stability with robust error handling. Achieved 50K+ impressions with 99.9% uptime.
