Machine Learning Projects in Biomedical Computing

I'm Arel, a high-school student learning machine learning through projects in medicine, biology, and a few other fields. Each project has a write-up, code, and a browser demo. The write-ups include the data splits, test results, and mistakes I found along the way. These are educational projects, not medical devices.

Biomedical projects

MoleCheck

Privacy-preserving skin-lesion analysis: a YOLO11 computer-vision classifier trained on 11,720 dermatology images, running fully on-device via Flutter and TensorFlow Lite so no user data leaves the phone.

ECG Arrhythmia Classification

A 1D convolutional neural network for heartbeat classification on the MIT-BIH database, with an inter-patient evaluation documenting the drop from 96% in controlled settings to 44% on unseen patients.

ADHD Classification from EEG

A multi-channel 1D CNN classifying pediatric EEG by study group, evaluated with a strict subject-level split to measure genuine generalization — 92% accuracy on unseen subjects.

Leukemia Cell Subtyping

A computer-vision classifier subtyping leukemic blood cells across four classes at 99.8%, with a critical analysis of why that figure reflects a dataset limitation rather than true clinical performance.

Research

Language of the Clue

A bilingual cognitive-load experiment: does a clue in your weaker language slow visual search, memory and reasoning, make you miss a hidden gorilla, or tire you faster? Built and tested; awaiting mentor review and ethics approval — no data collected yet.

Additional projects

Two projects outside the biomedical focus, included to show broader range in computer science — reinforcement learning and applied machine learning on financial time series.

Stock Volatility & Sentiment

A neural network predicting next-week volatility risk from price and news-sentiment features, including a controlled ablation demonstrating that the sentiment signal did not improve performance.

Autonomous Pentest Agent

A reinforcement-learning agent that learns efficient vulnerability-discovery strategies against a sandboxed web application, outperforming a random baseline sixfold — with a defensive extension for detecting agentic ransomware.

Computer Science + Bioengineering

The biomedical projects above map onto the CS + Bioengineering path at Illinois: the EEG and ECG work sits alongside Grainger's neural-engineering focus, while the dermatology and blood-smear classifiers align with its bioimaging and computational-and-systems-biology research. The write-ups explain the evaluation splits and model limitations. Read the full CS + BIOE breakdown →
