Simple explanation of convolutional neural network | Deep Learning Tutorial 23 (Tensorflow & Python)

A very simple explanation of convolutional neural network or CNN or ConvNet such that even a high school student can understand it easily. This video involves very less math and is perfect for total beginner who doesn't have any idea on what CNN is and how it works. We will cover different topics such as,
1. Why traditionally humans are better at image recognition than computers?
2. Disadvantages of using traditional artificial neural network (ANN) for image classification.
3. How human brain recognizes images?
4. How computers can use filters for feature detection
5. What is convolution operation and how it works
6. Importance of ReLU activation in CNN
7. Importance of pooling operation in CNN
8. How to handle rotation and scale in CNN

Just one doubt. How does it learn what will be the kernel matrix grid values. Coz the grid values of feature matrix were already provided by you, so how does it come to know by its own?

I scoured the web for explanations of convolution, and found them to be instructions rather than explanations, or explanations put in terms that only people who already knew about the topic could easily understand. Your explanation was absolutely the most clear I've seen, and I grasped the concept halfway through. Congratulations! You should write a book and teach a course; you have a talent for explanation.

[@cory99998]

This is surprisingly easy to understand. Thanks, I feel like I can imagine how many neural nets operate now. I felt like there should be a way to create 'filters' but didn't realize how straightforward it was (but also so potentially complex)

Dhaval Sir - I am a product of Indian education system - taught by teachers and professors in schools & colleges while was also trained by coaching institutes i.e. unorganized sector. I have also studied in the US for a short while. Hence, I can speak from experience. I would say you bring the best of all 3 worlds. Your style and delivery are so on point and effective that they are almost unmatchable! You have got this uncanny ability to connect the dots and create an effective transition from theory to the practical implementation of a concept. Please accept my heartiest thanks and gratitude for the immense service you're doing. You're hands down the best ML trainer at the moment on KZbin. Hope to meet you personally sometime in India or the US. Your videos are awesome. Keep 'em coming !! :)

Arun, thanks for very detailed and useful feedback. This way I at least know my strengths and continue to produce more content using those. I myself struggled during my studies and even today whenever I try to understand complex subject (such as CNN), my whole goal is to make explanations extremely easy so that even a dumb person can understand. From your comment it looks like I have fulfilled part of that mission.

[@c1inward346]

I love you're explanation, very intuitive in how you go about things. as a testament to that fact, when you consider classifying an image of a monkey let's say - a monkey has an eye, ear, nose, mouth, hands, legs, and tail - you take the original image of your monkey and apply convolutional operation (filter operation) to create your convolutional map for these small parts that make up a monkey. the filter map is not restricted to just a 3 x 3 filter, you could have a 4 x 4 or a 5 x 5, etc. then from these individual filter maps you aggregate the maps to form a larger generalization for the monkey (does the part correspond to a body or a head perhaps?) to which you can infer the class of the animal to be a monkey or not. a very interesting video, and I'm sorry if my explanation doesn't do the concept justice but I'm pretty sure it's somewhere along those lines 🙂.
