Dive into Neural Networks

Introduction to Neural Networks

Neural Networks are the fundamental building blocks of AI and are designed to mimic the structure and functioning of biological brains. They consist of interconnected nodes called neurons, organized into layers. Each neuron receives inputs, performs calculations, and produces an output that is passed to the next layer. The final output is the result of the network’s computation.

Working Principles

Neural Networks work by using weights and biases to adjust the strength of connections between neurons. During the training phase, the network iteratively updates these weights and biases to minimize the difference between its predicted outputs and the true outputs. This process, known as backpropagation, involves calculating and minimizing the network’s predictive error using optimization techniques.

Types of Neural Networks

There are several types of Neural Networks, each designed for specific tasks. Feedforward Neural Networks are the most basic type, where inputs flow forward through layers to produce outputs. Recurrent Neural Networks have feedback connections, allowing them to process sequential data such as time series or natural language. Convolutional Neural Networks excel at processing grid-like data, such as images, and are widely used in computer vision tasks.

Building Neural Networks

Building Neural Networks requires defining the network architecture, which includes the number of layers, type of activation functions, and optimization algorithms.
