Understand Different Types of Neural Networks

Neural networks come in various architectures, each suited for specific types of problems. Familiarize yourself with the most common types:

  • Feedforward Neural Networks: The simplest type of neural network where connections between nodes do not form a cycle.
  • Convolutional Neural Networks (CNNs): Particularly effective for image recognition and processing tasks.
  • Recurrent Neural Networks (RNNs) and Long Short-Term Memory (LSTM) Networks: Ideal for sequential data such as time series analysis or natural language processing.

Understanding the strengths and limitations of each type of neural network will help you choose the right architecture for your projects.
