Welcome to the lesson on Neural Network Basics! In this section, we will delve into the fundamentals of neural networks, which are at the heart of deep learning.

What is a Neural Network?

A neural network is a series of algorithms that attempt to recognize underlying relationships in a set of data through a process that mimics the way the human brain operates.

Components of a Neural Network

  • Neurons: The basic building blocks of a neural network.
  • Weights: These are the parameters that determine the strength of the connections between neurons.
  • Bias: It is a value added to the weighted sum of inputs.
  • Activation Function: Determines whether a neuron should be activated or not.

Types of Neural Networks

  • Feedforward Neural Networks: The simplest type of neural network.
  • Convolutional Neural Networks (CNNs): Used primarily for image recognition.
  • Recurrent Neural Networks (RNNs): Ideal for sequence data like time series or natural language.

Applications of Neural Networks

  • Image Recognition
  • Natural Language Processing
  • Speech Recognition
  • Autonomous Vehicles
