But what is a Neural Network? Deep learning - Part 1 of 4

The video introduces the concept of neural networks, focusing on their structure and function. It explains how humans recognize digits effortlessly and how neural networks attempt to replicate this process. The video covers the basics of neurons, layers, weights, biases, and activation functions, using a simple neural network model to recognize handwritten digits. It also discusses the importance of matrix representation in understanding neural networks and hints at the learning process, which will be covered in a subsequent video.

Discuss the challenges of recognizing sub-components of digits in a neural network.

What is the purpose of the sigmoid function in a neural network?

What is the relationship between linear algebra and machine learning?
