Artificial neurons are the main parts of a neural network. They work like human brain neurons. They take in inputs, work on them, and send out outputs to other layers.
There are many layers in these networks, and each one does something different. The input layer takes in raw data. It sets the stage for what comes next. Then, there are many hidden layers. They work on the data to find features and patterns. The final step happens in the output layer. This is where the system makes predictions or sorts data.
Weights and biases play a big part in how neural networks function. Weights decide how much influence input signals have. Biases help adjust outputs to get closer to the right answers during training.
Adjusting weights and biases is key for AI to learn from data. This happens through backpropagation and gradient descent. It’s a big part of how neural networks get better at what they do.
