Projects
Two kinds of work: self-directed machine learning projects with public code and results, and software I have built professionally.
Research & learning
Projects I use to build a foundation for machine learning research. Every result shown comes from a run I actually made.
Imbalanced Classification Benchmarks
Comparison of cost-sensitive weighting, SMOTE and random undersampling against untreated baselines on three medical datasets, using 5-fold stratified cross-validation scored with PR-AUC instead of accuracy.
Committed result: balancing methods mostly improved recall rather than ranking, and made little difference when imbalance was mild.
Vision Baselines
Reproducible PyTorch training harness for CIFAR-10 with LeNet and a CIFAR-stem ResNet-18: deterministic seeding, cosine learning-rate schedule, per-epoch metrics logged to CSV.
LeNet reaches 80.25% test accuracy in 30 epochs; the ResNet-18 run is in progress.
Semantic Image Search
Text-to-image search over local photo collections using pretrained CLIP embeddings, with an incremental embedding index and a command-line interface for natural-language queries.
Working retrieval tool; index updates without re-embedding unchanged images.
Software Foundations
Worked exercises from Software Foundations Volume 1 in the Coq proof assistant: functional programming and proofs by induction, checked by the proof checker.
Ongoing; Basics chapter complete.
