What is Deep Learning?

Deep learning is a subset of machine learning that focuses on using artificial neural networks to model and understand complex patterns. **It involves training deep neural networks with multiple hidden layers to learn and extract intricate representations from raw data**. Unlike traditional machine learning algorithms, deep learning models can automatically discover hierarchical patterns and features from the data.

How Does Deep Learning Work?

Deep learning models are built using artificial neural networks composed of interconnected nodes or artificial neurons, inspired by the human brain’s structure. The connections between neurons have associated weights, which are adjusted during the training process. **The objective of deep learning is to optimize these weights, enabling the network to make accurate predictions**.

During training, deep learning models are exposed to labeled data and iteratively learn from it, gradually updating the weights to minimize the difference between predicted and actual outputs. This process is known as backpropagation, where the network’s error is propagated back through the layers, adjusting the weights accordingly. **This iterative training allows the model to discover complex patterns and relationships in the data**.
