What is a Kalman filter used for?

Estimating system states like position/velocity from noisy sensors — GPS, robotics, finance even.

How does Kalman filter work in self-driving cars?

Fuses LiDAR, radar, cameras for precise localization, predicting paths amid urban chaos.

Is Kalman filter better than machine learning for tracking?

For real-time, low-power? Yes. ML complements, doesn't replace.

Kalman Filters: The Old-School Math Keeping Your Drone from Crashing

Picture a drone veering wildly in the wind, sensors screaming conflicting data. Enter the Kalman filter: it cuts through the noise, predicts the truth, and keeps things flying straight.
