The process involves algorithms that adjust and improve over time with increased data exposure, facilitating predictive analytics and complex problem-solving. This methodology underpins applications ranging from email filtering to more complex tasks like self-driving cars.

Deep Learning

Deep learning, a subset of machine learning, utilises layered neural networks to emulate the human brain’s decision-making process. These networks, composed of numerous interconnected nodes, can analyse large volumes of data. They excel at recognising patterns in unstructured data such as images and speech. Deep learning has been instrumental in advancements like image and speech recognition technologies.

Neural Networks

Neural networks are computing systems vaguely inspired by the biological neural networks that constitute animal brains. An artificial neural network contains layers of interconnected nodes (neurons), with each layer tasked to perform specific operations. Their structure allows them to adapt and learn from observational data, which is pivotal in areas such as handwriting recognition and natural language processing. The strength of neural networks lies in their versatility and robustness in handling a vast array of tasks within AI.

Applications of AI
