Core
CV Architectures: ResNets, ViT, DetectionModern computer vision stands on three pillars: residual connections that let CNNs reach hundreds of layers deep without degrading, Vision Transformers that patchify an image and run self-attention in place of convolutions, and detection heads (one-stage vs two-stage) scored by mAP after non-maximum suppression. AI, ML, and GenAI engineer interviews probe this to check that you can pick an architecture, fine-tune a pretrained backbone, and reason about latency vs accuracy rather than train from scratch.📊 Evaluation & ML FoundationsSign in

Object Detection and SegmentationDetection finds objects as boxes plus labels; segmentation labels pixels (semantic) or per-object pixels (instance). The machinery is shared: a pretrained backbone feeds a head, anchors or queries propose objects, IoU measures box overlap, and NMS strips duplicates. Two-stage detectors (Faster R-CNN) trade speed for accuracy, one-stage (YOLO) flip it, and Mask R-CNN adds a mask branch for instance segmentation. AI, ML, and GenAI engineer interviews probe this to see you pick by latency and accuracy and know what NMS, IoU, and anchors actually do.📊 Evaluation & ML FoundationsSign in
