#146 Explain how you would auto-label a fleet dataset and what quality controls you would apply. ★
#147 Detect and handle distribution shift between fleet data and the training set. ★
#148 Handle extreme class imbalance in rare-event detection (e.g., a child running into the road). ★
#149 Design the neural network architecture for multi-camera 3D object detection without lidar. ★
#162 Explain how to fuse camera, radar, and IMU into one perception stack and where the fusion should happen. ★
#205 Quantize and prune a vision model for a fixed onboard compute budget without losing recall on small objects.
#272 Design the data engine: fleet triggers → upload → labelling → retraining → shadow-mode validation → release.
#273 Explain how you would actually measure whether an autonomy release is safer than the last one, given disengagement rate is a weak proxy.
#308 Implement non-maximum suppression, then vectorize it.
#332 Implement an efficient ring buffer for high-rate sensor data with a fixed memory budget.
