What are Neural Networks and Deep Learning?

Neural networks are a computational paradigm inspired by the way biological neural networks in the human brain process information. They consist of interconnected nodes or neurons, organized in layers, enabling the network to learn from complex data and make predictions. On the other hand, deep learning is a subset of machine learning that utilizes deep neural networks with multiple layers for feature extraction and transformation, ultimately leading to enhanced learning models.

Explanation of Neural Networks

Neural networks operate by receiving input signals, processing the information through interconnected layers of neurons, and producing an output based on the learned patterns. This iterative process allows the network to adapt and improve its predictive capabilities over time.

Introduction to Deep Learning

Deep learning extends the capabilities of neural networks by introducing multiple hidden layers, enabling the network to automatically discover intricate representations of the input data. This hierarchical feature learning is pivotal in tasks such as image and speech recognition.

Relationship Between Neural Networks and Deep Learning
