Innovations like IBM’s Deep Blue, the first computer to defeat a world chess champion, and emergent technologies like self-driving cars exemplify the strides made in AI capabilities.

Foundations of AI

The underpinnings of Artificial Intelligence (AI) are crucial to understanding its capabilities and potential applications. They explore how machines can mimic cognitive functions associated with human intellect such as learning and problem-solving.

Machine Learning

Machine learning is a subset of AI focused on the idea that systems can learn from data, identify patterns, and make decisions with minimal human intervention. 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

Artificial Intelligence (AI) is reshaping numerous industries, enhancing efficiency and enabling new capabilities. Here are specific ways AI is applied in various sectors:


In healthcare, AI systems assist with diagnostic procedures, analysing medical images to detect abnormalities and diseases, such as cancer, with high accuracy. AI-driven predictive analytics are also employed to anticipate patient admissions and manage hospital resources effectively.


The finance sector utilises AI for algorithmic trading, where algorithms execute trades at speeds and volumes beyond human capability. AI also plays a crucial role in fraud detection by recognising unusual patterns indicative of fraudulent activity, thereby securing transactions.
