What is Machine Learning?

Machine Learning (ML) is a branch of Artificial Intelligence (AI) that teaches computers to learn from data and improve performance on tasks without being explicitly programmed for every scenario. By analysing large datasets, machine learning systems identify patterns and use them to make accurate predictions or informed decisions.

In simple terms, machine learning helps answer questions such as:

• How can customer behaviour be predicted more accurately?

• Which emails or messages are likely to be spam?

• How do systems recognise images, speech, or text?

• How can businesses automate decisions using data?

Machine learning enables systems to become smarter over time, making it a core technology behind many modern digital applications.
