The MOSAIC Engine
Inside LifeSigns runs MOSAIC (Multi-modal Offline Statistical Analysis and Insights Correlator), a highly advanced on-device analytics engine. It securely processes millions of data points locally to transform your raw health metrics into proactive, contextual wisdom.
Comprehensive Data Fusion
MOSAIC silently ingests over 115 dimensions across 14 life modalities. This ranges from your deepest sleep stages and heart rate variability to real-time weather conditions, location history, calendar load, and workout intensity.
By fusing these distinct modalities into a unified temporal sequence, the engine begins to see the structure of your days rather than just isolated charts.
Personalized Temporal Baselines
Using sophisticated on-device sequence modeling, MOSAIC learns your deeply personal baseline. It understands that a resting heart rate of 55 bpm might be normal for you in winter, but elevated in the summer.
The model continually adapts to your evolving rhythms, ensuring thresholds are calibrated exclusively to your body's specific history, rather than rigid population averages.
Hybrid ML & Deterministic Rules
MOSAIC utilizes a dual-layer approach. The Machine Learning Anomaly Detector acts as an early-warning radar, catching invisible, complex relational deviations ("The Check Engine Light").
Simultaneously, a deterministic layer interprets these anomalies using clinical thresholds, ensuring every insight is verifiable and rooted in actionable science ("The Mechanic").
Proactive & Predictive Insight
We've moved beyond retrospective analysis into predictive guidance. MOSAIC uses your foundational model to forecast outcomes like impending burnout or reduced output energy.
Using advanced counterfactual reasoning (simulating the "what-ifs" of your behavioral choices) the engine surfaces the highest-impact actions you can take today to optimize tomorrow.
Federated Intelligence, Zero Cloud
The massive computational effort required by the MOSAIC engine happens entirely on your iOS device while it charges overnight. Your 115-dimension daily arrays are never transmitted to our servers, establishing a new paradigm in absolute privacy.
