What is Deep Learning?
Deep learning involves the use of neural networks that mimic the human brain’s structure to analyze data. These networks are composed of multiple layers, allowing them to learn and represent data in a hierarchical manner. This hierarchical learning enables deep learning models to recognize patterns in images, speech, and text with remarkable accuracy.
Why Learn Deep Learning?
Learning deep learning opens doors to a wide range of applications across industries. From healthcare to finance, deep learning models can analyze vast amounts of data, predict outcomes, and automate tasks. For instance, in healthcare, deep learning can help diagnose diseases from medical images, while in finance, it can predict stock prices and detect fraud.
