Hello,
I'm ZiWei Guo
Computer Scientist & Mathematician
I have a strong foundation in Large Language Models, machine learning, operations research, and data science. My analytical skills and experience enable me to solve complex problems and drive data-driven decisions. I'm passionate about Web3, blockchain, and cryptocurrency, exploring their intersections with AI to drive innovative, decentralized solutions and push the boundaries of the next digital era.
Beyond the binary and bytes, I'm a tenor who sings opera in both church and college choirs, and I've been playing guitar for over a decade. Whether I'm decoding data or belting out a high C, I'm all about creating something extraordinary!

Showcasing my projects and achievements
OTTO Multi-Objective Recommender System
In the OTTO Multi-Objective Product Recommendation competition, I played a key role in securing a silver medal, placing our team in the top 2% globally, with a ranking of 66th out of 2,574 teams. The competition required predicting user actions—clicks, favorites, and purchases—over a seven-day window based on historical user data. Our approach was multifaceted, starting with dynamically shortlisting product candidates using diverse recall methods, including top historically clicked/favorited/purchased items, as well as product similarities derived from Word2Vec models and co-occurrence matrices. This step effectively reduced the candidate pool to the top 200 most probable items. To refine predictions, we engineered a rich feature set encompassing product-specific, user-centric, and product-user interaction features, using both recent (one-week) and longer-term (four-week) behavioral data. We then employed an LGB binary classification model to generate final recommendations, selecting the top 20 product IDs based on predicted probabilities. This method delivered a leaderboard score of 0.585, securing our place in the top 2% of participants worldwide.
G2Net Gravitational Waves Detection
In the G2Net Continuous Gravitational Waves Detection competition, I contributed to a team that earned a silver medal, securing 26th place among 936 teams—positioning us in the top 2%. The challenge was to detect faint, continuous gravitational wave signals from rapidly rotating neutron stars in cosmic image data, with performance evaluated using the AUC metric. Our approach relied on deep learning techniques, where we extracted image files from HDF5 datasets and developed models using EfficientNet0 and InceptionV4 architectures. We optimized model training with a binary loss function and the Adam optimizer, leveraging hyperparameter tuning with Optuna for further improvement. To enhance model robustness, we applied data augmentation strategies such as flipping, cutmix, and mixup. Finally, we combined the predictions using a linear-weighted ensemble of EfficientNet0 and InceptionV4, achieving public and private scores of 0.76x and securing our position in the top 2% of the competition.
RSNA Breast Cancer Detection
In the Kaggle RSNA competition on breast cancer diagnostics, I led the development of a robust solution for a challenging binary classification task involving CT imaging data. I utilized NVIDIA's DALI framework to significantly accelerate preprocessing, transforming raw scans into structured image formats efficiently. I applied advanced edge-detection algorithms to isolate breast regions, reducing noise and improving data quality. Leveraging the ConvNetV2 architecture, I optimized model performance with a comprehensive data augmentation strategy, including techniques like image rotation, brightness adjustments, and adaptive cropping. I further enhanced model training by employing the AdamW optimizer alongside Stochastic Weight Averaging (SWA) and implemented a rigorous five-fold cross-validation to ensure model reliability. These efforts culminated in a high-performing ensemble model, fine-tuned with pF1 probability thresholding, resulting in a bronze medal and a ranking of 110th out of 1,687 participants—placing me in the top 6% of competitors globally.
Distributed Pub/Sub Middleware with ZeroMQ & ZooKeeper
Designed a custom publish-subscribe middleware layer using ZeroMQ and ZooKeeper, implementing hybrid dissemination strategies and fault tolerance mechanisms that improved system modularity by 25% and reduced message delivery latency by 30%.
Lost & Found Web Application
