Predictions

Eight windows into your future self

Prediction is not fortune-telling. It is pattern recognition at scale—finding the signal in the noise of your daily life and projecting it forward with mathematical precision.

01

Energy Forecasting

85% accuracy · ±1 point

Your energy tomorrow is not random. It is the mathematical consequence of how you slept, how stressed you were, how much you moved, and what your body has learned to expect. AURA reads these signals and projects 24 hours ahead.

Ensemble Prediction
E(t+24) = 0.4·RF(sleep, stress, exercise, mood) + 0.4·GB(Δenergy, Δstress, history) + 0.2·LR(baseline_features)
Inputssleep_hours, sleep_quality, stress, exercise_minutes, mood, water_intake
Outputenergy_score (1–10), confidence_interval
ModelEnsemble (RF + GB + LR)
02

Mood Prediction

80% accuracy · ±1 point

Mood is not a mystery—it is a function. Sleep quality, social context, physical activity, and accumulated stress all feed into an emotional state that AURA can anticipate before you feel it. Knowing your mood tomorrow lets you prepare for it today.

Bayesian Conditional
P(mood_high | sleep_good, stress_low, exercise_yes) = 0.78 P(mood_low | sleep_poor, stress_high) = 0.82
Inputssleep_quality, stress_level, exercise_done, social_activity, prior_mood
Outputmood_score (1–10), mood_category
ModelBayesian Network + Ensemble
03

Stress Trend Analysis

75–85% accuracy

Stress does not arrive suddenly. It builds—slowly, invisibly—until it overwhelms. The Statistical Analyzer watches the trajectory of your stress over days and weeks, detecting the upward slope before it becomes a cliff.

Trend Detection
MA₇(stress) = (s₋₆ + s₋₅ + ... + s₀) / 7 slope = LinearRegression(MA₇).coef_ alert = slope > 0.15 AND MA₇ > 6.5
Inputsstress_history (30 days), sleep_trend, workload_proxy
Outputtrend_direction, peak_estimate, days_to_peak
ModelStatistical Analyzer (moving average + regression)
04

Sleep Quality Optimization

80% accuracy

Not all sleep is equal. Seven hours of fragmented sleep is not the same as seven hours of deep rest. AURA learns your personal sleep architecture—what conditions produce restorative sleep for you specifically—and recommends accordingly.

Quality Score
Q = 0.35·duration_score + 0.30·consistency_score (same bedtime ±30min) + 0.20·pre_sleep_stress_inv + 0.15·exercise_lag_score (exercise 4–6h before)
Inputsbedtime, wake_time, stress_evening, exercise_timing, caffeine_proxy
Outputpredicted_quality (1–10), optimal_bedtime, recommendations
ModelEnsemble + Reinforcement Learning
05

Burnout Risk Assessment

90% early warning

Burnout is the most dangerous pattern AURA watches for. It is the convergence of sustained high stress, declining energy, deteriorating sleep, and eroding mood—a slow collapse that most people don't see coming until it has already arrived.

Risk Score
R = w₁·(stress_14d_avg / 10) + w₂·(1 - energy_14d_avg / 10) + w₃·(1 - sleep_14d_avg / 9) + w₄·(1 - mood_14d_avg / 10) alert_threshold = R > 0.72 → HIGH RISK
Inputs14-day rolling averages: stress, energy, sleep, mood
Outputrisk_score (0–1), risk_level, contributing_factors
ModelStatistical Analyzer + weighted composite
06

Optimal Activity Timing

75% accuracy

The same activity at different times produces different results. A morning run when your energy is naturally high yields different outcomes than the same run at 9 PM when your body is winding down. AURA maps your chronotype and finds your windows.

Markov State Transition
P(high_performance | state=morning_high_energy) = 0.74 P(high_performance | state=evening_low_energy) = 0.31 optimal_window = argmax P(performance | time, current_state)
Inputsactivity_type, time_of_day, current_energy, historical_performance
Outputoptimal_time_window, expected_performance_score
ModelMarkov Chain + Reinforcement Learning
07

Recovery Needs

85% accuracy

Recovery is not laziness—it is a biological requirement. AURA tracks your accumulated stress debt and energy deficit, predicting when your body needs rest before you feel the crash. Prevention is always more effective than recovery.

Deficit Accumulation
stress_debt = ÎŁ max(0, stress_i - 5) for i in last_7_days energy_debt = ÎŁ max(0, 6 - energy_i) for i in last_7_days recovery_rec = stress_debt > 8 OR energy_debt > 6
Inputs7-day stress history, energy history, exercise_intensity_sum
Outputrecovery_needed (bool), recovery_type, estimated_days
ModelStatistical Analyzer + threshold rules
08

Performance Windows

80% accuracy

Peak performance is not a constant state—it is a window. AURA identifies the convergence of high energy, positive mood, low stress, and good sleep that creates your optimal cognitive and physical performance conditions.

Performance Index
PI = (energy/10)^0.4 · (mood/10)^0.3 · (1 - stress/10)^0.2 · (sleep_quality/10)^0.1 peak_window = PI > 0.72 → schedule demanding tasks
Inputsenergy, mood, stress, sleep_quality, time_of_day
Outputperformance_index (0–1), window_duration, task_recommendations
ModelEnsemble + composite index
