16 stops · basics first
  1. Machine Learning ✓ understood

    Building systems that learn patterns from data instead of following hand-written rules, getting better at a task as they see more examples.

  2. Supervised Learning ✓ understood

    Learning from examples paired with the correct answer, so a model can predict answers for new inputs it hasn't seen.

  3. Classification ✓ understood

    A supervised learning task where the model assigns each input to one of a fixed set of categories, such as spam or not spam.

  4. Neural Network ✓ understood

    A computational model inspired by biological neural networks, consisting of interconnected nodes (neurons) organized in layers that process information through weighted connections.

  5. Deep Learning ✓ understood

    A subset of machine learning that uses neural networks with multiple layers (deep neural networks) to learn hierarchical representations of data.

  6. Computer Vision ✓ understood

    The field of AI that gets computers to extract meaning from images and video: what is in them, where it is, and how it moves.

  7. Semantic Segmentation ✓ understood

    Classifying every pixel in an image into categories, creating a pixel-level understanding of scenes.

  8. Bounding Box ✓ understood

    A rectangular box defined by coordinates that localizes an object in an image, used in object detection.

  9. Object Detection ✓ understood

    Finding every object of interest in an image and giving each a class label, a confidence score and a bounding box.

  10. Instance Segmentation ✓ understood

    Combining object detection and segmentation to identify individual object instances at the pixel level.

  11. Convolution ✓ understood

    A mathematical operation that applies filters/kernels to input data to extract features like edges, textures, and patterns.

  12. Convolutional Neural Network ✓ understood

    A neural network that scans images with small learned filters, reusing the same weights at every position to build up from edges to whole objects.

  13. R-CNN ✓ understood

    Region-based CNN - an object detection approach using selective search and CNN features.

  14. Anchor Box ✓ understood

    Predefined boxes of various sizes and ratios serving as references for object detection.

  15. Region Proposal Network ✓ understood

    A network generating candidate object locations for two-stage detectors like Faster R-CNN.

  16. Faster R-CNN ✓ understood

    An object detection architecture with RPN for efficient region proposals.
