Introduction:
Artificial Neural Networks (ANNs) have become increasingly popular due to their ability to simulate the behavior of biological neurons and process and learn from information. They have shown remarkable performance in areas such as image recognition, natural language processing, and pattern prediction. ANNs consist of interconnected nodes called neurons, organized into layers, which receive and transmit signals. Activation functions play a crucial role in determining the output of neurons by introducing non-linearities into the network. Feedforward propagation is the process by which information flows through the network, while weight adjustment and backpropagation are essential for training the network. Overfitting can be mitigated through regularization techniques. Other types of ANNs include Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), Long Short-Term Memory (LSTM) networks, and Gated Recurrent Units (GRUs). Deep Learning focuses on the development and training of deep neural networks, while Transfer Learning leverages pre-trained networks for new tasks. Reinforcement Learning is a learning paradigm where an agent interacts with its environment. Understanding the inner workings of ANNs unlocks their full potential and paves the way for exciting advancements in the future.
