Big Data CBT
For non-majors the hard part is knowing where to start. That part is free here.
Members trade tips and rebuild the exam after sitting it — anonymous, no signup, nobody paid.
bigdata-cbt-eight.vercel.app→ChartOneShot
7 minutes → 30 seconds. Years of scattered EMR notes, read as one timeline.
Longitudinal EMR AI — split-view comparison, temporal summaries and acronym expansion, stitched into one specialty-ordered page.
chartoneshot.com→FitLLM
Most LLM memory calculators are ~11× wrong on modern attention. This one isn't.
Per-layer modeling of sliding-window, linear and MoE attention predicts whether an LLM fits your Mac's unified memory — verified against official HuggingFace configs. Free & open source.
fitllm.run→XAI Transformer
8,000 test cases, 100% accuracy — explainable weight logic without gradient-based training.
Dissects the Attention mechanism to answer one question: how does AI decide? Visualized through interactive attention maps.
xai-calculator.vercel.app→Mentality Pipeline
Five real-time streams, one monotonic clock — quantifying what every quant system silently ignores: the trader.
POS rPPG, MediaPipe 478, and BLE pulse on one clock — "Brow tension preceded the loss by 3.2 seconds, three times this week."
evm-rppg.vercel.app→Actionable Vision Agent
Translating raw CCTV streams into operational automation.
YOLO11-seg + ByteTrack hold identity through 70% occlusion — direct alerts.
