When your A/B test is lying anyway
You randomized correctly and read the statistics honestly, and the experiment can still give the wrong answer, because the clean logic assumes things that are not always true. Learn how users affecting each other breaks the method, why a short test misjudges a long-run effect, how an average hides opposite effects in subgroups, and the reflex of distrusting results that look too good.
LiDAR and Point Clouds
How LiDAR fires pulses and measures time-of-flight to build a 3D point cloud; data structures, voxel downsampling, ICP registration, ground segmentation, and an honest comparison with cameras for robot perception.
