00:00welcome to day 17 of wisdom academy ai my incredible wizards i'm anastasia your thrilled
00:15ai guide and i'm buzzing with excitement ever wondered how ai recognizes faces or objects in
00:21photos today we're diving into convolutional neural networks cnn's the magic behind image
00:26recognition sophia's here to make it unforgettable with a demo over to you sophia
00:31cnn's are our star today and i'm so excited convolutional neural networks are deep learning
00:41models for image processing they detect patterns like edges and textures excelling in tasks like
00:46classification and object detection inspired by the human visual system cnn's are a magical leap in
00:53ai vision get ready to be amazed by their power let's dive deeper
00:57why use cnn's i'm so thrilled to share they process images efficiently reducing parameters compared to
01:09standard networks cnn's learn hierarchical features from edges to complex objects and outperform
01:16traditional methods in vision tasks for example they power object detection in self-driving cars
01:21this is ai vision at its finest let's see why they're so magical
01:25let's see how cnn's work it's magical the input is an image represented as pixel numbers
01:36convolution detects features like edges creating feature maps pooling reduces their size while
01:42keeping key features and fully connected layers make predictions this pipeline transforms images
01:47into insights i'm so excited to break it down
01:49training cnn's is fascinating the forward pass sends images through layers to predict we calculate
02:00loss by comparing predictions to actual labels back propagation adjusts weights and gradient descent
02:06optimizes them this process crafts powerful models i'm so excited to train one
02:11cnn's cnn's that's a wrap for day 17 my amazing wizards i'm anastasia and i'm so grateful you joined
02:40us to explore cnn's it's been a magical journey your true wizards for diving into image recognition
02:45like subscribe and hit the bell for more lessons tomorrow we'll explore recurrent neural networks
02:51and guess what two new wizards will join us to spark even more curiosity
