ML is typically divided into three types:

Supervised learning: The system is trained on labeled data, learning from examples to predict outcomes based on input data.
Unsupervised learning: The algorithm identifies hidden patterns in unlabeled data, commonly used in customer segmentation and clustering.
Reinforcement learning: The algorithm learns by trial and error, receiving feedback through rewards or penalties to maximize performance. This is crucial for applications like autonomous vehicles.

Deep learning

Deep learning is a specialized subset of machine learning that mimics the neural networks of the human brain to analyze and process data. Using multi-layered neural networks, deep learning can model complex patterns in data, making it especially useful for image recognition, speech processing, and language translation. It powers advanced technologies like facial recognition systems, virtual assistants (e.g., Alexa or Siri), and autonomous driving systems.

One of the primary reasons deep learning has surged in popularity is its ability to perform tasks at a scale and accuracy level that traditional ML models cannot match. For instance, deep learning models can process vast amounts of unstructured data—like images or videos—much faster and with higher precision. The algorithm gets stronger as it learns from increasingly large datasets, thanks to the multiple layers within its neural network that allow for higher levels of abstraction and complexity.

In real-world applications, deep learning has revolutionized industries like healthcare, where it is used to detect diseases in medical images more accurately than human doctors. It's also integral to natural language processing (NLP), allowing machines to understand and respond to human language in customer service chatbots or virtual assistants.
