Understanding Neural Networks
Neural networks are computational models inspired by the structure and functionality of the human brain. They consist of interconnected nodes, referred to as neurons, organized into layers. Each neuron receives inputs, processes them, and sends the output to other connected neurons. The connections between neurons have associated weights that determine the strength of the signal passing through.
***Neural networks can be trained using a method called backpropagation, where errors are propagated backwards through the network to adjust the weights and improve the accuracy of the model.*** This learning process continues iteratively until the network reaches a desirable level of performance.
One key benefit of neural networks is their ability to learn from data and adapt to different scenarios. They have been successfully applied in various domains, such as image and speech recognition, text analysis, and predictive modeling.
