Deep Neural Networks are advanced machine learning models inspired by the human brain, consisting of multiple layers of interconnected nodes or neurons. Each layer transforms input data into increasingly complex representations, allowing the network to learn intricate patterns and relationships. These models excel at tasks like image recognition, natural language processing, and speech recognition, as they can automatically extract and combine features from raw data, leading to highly accurate predictions and classifications.
