Explainable AI (XAI)
Explainable AI (XAI) refers to the ability of an artificial intelligence system to provide understandable explanations or justifications for its decisions or predictions. It aims to bridge the gap between complex AI algorithms and human comprehension by providing insights into the reasoning and factors considered by the AI model. XAI techniques help enhance transparency, trust, and accountability, allowing users to understand and validate the AI system’s behaviour.
Expert systems are AI systems that mimic the decision-making capabilities of human experts in specific domains. They use a knowledge base of rules and facts to reason and make intelligent decisions. Expert systems can advise, diagnose problems, or recommend solutions by applying inference mechanisms. Expert systems have been used in various fields, including medicine, finance, and engineering, to capture and utilise expert knowledge for complex problem-solving.
Generative Adversarial Networks (GANs)
Generative adversarial networks (GANs) are a class of machine learning models consisting of two components: a generator and a discriminator. The generator generates new data instances while the discriminator evaluates whether the generated data is real or fake. Through iterative training, GANs learn to develop increasingly realistic and high-quality synthetic data, making them powerful tools for image synthesis, text generation, and more.
Generative AI is a branch of artificial intelligence that focuses on creating models capable of generating new and original content. These models learn patterns from existing data and then generate novel outputs such as images, text, music, or other forms of media.

NLG finds applications in automated report generation, chatbots, content creation, personalised messaging, and other scenarios where generating human-readable text is desired.
Natural Language Processing (NLP)
NLP deals with the interaction between computers and human language. It enables machines to understand, interpret, and generate human language, enabling applications like translation, sentiment analysis, and chatbots.
Neural networks are a fundamental component of AI and machine learning. 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.
Prompt engineering is designing and optimising the prompts or instructions given to a language model, enabling it to generate more accurate and desired responses based on specific inputs or queries.
Reinforcement learning is a machine learning approach where an agent learns to make sequential decisions through interaction with an environment. 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 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 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.
Visual AI applies artificial intelligence techniques to process and understand visual data, such as images and videos. It involves object detection, image classification, image segmentation, facial recognition, and scene understanding. Visual AI enables machines to perceive and interpret visual information, leading to applications like autonomous vehicles, medical imaging, surveillance systems, augmented reality, and image-based search and recommendation systems.
