8 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. 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.

  3. Convolution ✓ understood

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

  4. 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.

  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. Bounding Box ✓ understood

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

  8. Object Detection ✓ understood

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

  9. Feature Pyramid Network · you are here ✓ understood

A CNN architecture creating multi-scale feature representations for detecting objects at different sizes.

This concept is essential for understanding computer vision and forms a key part of modern AI systems.
