They are mathematical models inspired by the structure and functioning of biological neural networks consisting of interconnected artificial neurons. Neural networks process and analyse complex data to make predictions or decisions.


Overfitting happens when a machine learning model becomes overly specialised to the training data, losing its ability to generalise well to new, unseen data. The model fits the training data too closely, capturing noise and irrelevant patterns; this leads to reduced performance on new data and a lack of robustness. Techniques like regularisation and cross-validation help address overfitting.

The agent receives feedback in rewards or penalties based on its actions, allowing it to learn optimal strategies over time. Through trial and error, reinforcement learning enables agents to maximise long-term cumulative rewards, making it suitable for game-playing, robotics, and autonomous decision-making.

Robotic Process Automation (RPA)

Robotic Process Automation (RPA) involves using software robots or “bots” to automate repetitive, rule-based tasks traditionally performed by humans. These bots interact with existing software systems, mimicking human actions and following predefined rules and workflows. RPA enables organisations to streamline operations, increase efficiency, and reduce errors by automating tasks such as data entry, report generation, and data validation, freeing human workers for more complex and value-added activities.

Supervised Learning

Supervised learning is a type of machine learning where an algorithm learns from labelled data. In this approach, a model is trained with input-output pairs to discover patterns and make predictions on unseen data.


Underfitting occurs when a machine learning model is too simple or cannot capture the underlying patterns in the data. It fails to sufficiently learn from the training data, resulting in poor performance on the training data and new, unseen data. Underfitting can be mitigated using more complex models, increasing model capacity, or providing additional relevant features or data.

Unsupervised Learning

Unsupervised learning is a type of machine learning where an algorithm learns from unlabeled data. It seeks to identify patterns, group similar data points, or discover hidden data structures without predefined labels.
