Introduction to Deep Learning

Deep learning intro

Deep learning is a type of machine learning that helps computers learn patterns and make decisions without being explicitly programmed. It is widely used in image recognition, speech processing, medical diagnosis, self-driving cars, and many other applications.

Deep learning models use artificial neural networks (ANNs), inspired by the human brain, to learn from large amounts of data and improve accuracy over time. The concept dates back to the 1940s, when the first artificial neuron model was introduced, but major breakthroughs came in the 2010s with advancements in deep neural networks and large-scale computing.

Machine Learning vs. Deep Learning

ML vs Deep Learning

  • Machine Learning (ML): Uses algorithms that require human-designed features. Examples include decision trees and support vector machines.

  • Deep Learning (DL): Uses neural networks to learn features from raw data, making it better suited for tasks like natural language processing and computer vision.

Why Deep Learning Frameworks Matter

Learning Frameworks

Deep learning frameworks provide tools and libraries that simplify the process of building, training, and deploying AI models. They offer:

  • Pre-built functions for neural networks

  • Support for GPUs and TPUs for faster computation

  • Tools for handling large datasets

  • APIs for integrating AI into real-world applications
