Technology FAQ
How is prediction accuracy validated?
Our prediction accuracy is validated using rigorous machine learning methodology including cross-validation and held-out test sets. We compare predicted race times against actual race results across various distances (5K to marathon), ensuring predictions fall within an acceptable margin of error for race planning purposes.
What type of machine learning models does Fit PA use?
Fit PA uses an ensemble of machine learning models including gradient boosting, neural networks, and time-series forecasting models. Each model is specialized for different prediction tasks - some excel at short-term predictions while others handle long-term performance trends. The ensemble approach combines their strengths for superior overall accuracy.
How is my data protected?
All data is encrypted using AES-256 encryption both in transit (via TLS 1.3) and at rest. Our infrastructure is designed to meet SOC 2 Type II compliance standards. We implement multi-factor authentication, role-based access controls, and comprehensive audit logging. You can read more in our Privacy Policy.
Does the AI improve over time for my specific needs?
Yes! Fit PA's AI uses continuous learning to improve predictions for your individual profile. As it collects more data about your training responses, recovery patterns, and performance, the models become increasingly personalized. Most users see noticeably improved prediction accuracy after 4-6 weeks of consistent use.
What happens to my data if I stop using Fit PA?
You have complete control over your data. You can export all your training data at any time in standard formats. If you delete your account, all personal data is removed within 30 days, with backup data purged within 90 days. Anonymized, aggregated data may be retained for model improvement but cannot be traced back to you.
