The Foundation: Core AI Concepts
These are the fundamental terms that form the building blocks of artificial intelligence.
Artificial Intelligence (AI): The broad field of computer science dedicated to creating machines that can simulate human intelligence. This includes tasks like learning, reasoning, perception, and problem-solving.
Machine Learning (ML): A subset of AI that focuses on building algorithms that enable computers to learn from data without being explicitly programmed. It's how systems improve their performance over time.
Deep Learning: A subfield of machine learning that uses multi-layered neural networks to analyse complex patterns in data. This approach is behind many of the most impressive recent AI breakthroughs, including those in computer vision and natural language processing.
Generative AI: A type of AI that can create new content, such as text, images, code, or video, by learning from existing data. ChatGPT is a prime example of a generative AI tool.
Algorithm: A set of rules or instructions that a computer program follows to solve a problem or complete a task. In AI, algorithms enable models to learn and make predictions.
Neural Network: A computational model inspired by the human brain. It consists of interconnected nodes (neurons) organised in layers that process data and recognise patterns.
The Brains Behind the Chatbot: Large Language Models (LLMs)
ChatGPT and other powerful chatbots are built on a specific type of AI model. Here's the essential terminology.
Large Language Model (LLM): An AI model trained on a massive amount of text data to understand and generate human-like language. The "large" refers to both the vast dataset and the number of parameters the model contains.
GPT (Generative Pre-trained Transformer): The specific family of LLMs developed by OpenAI that powers ChatGPT. Pre-training is the initial phase where the model learns from a huge dataset of text and code.
Transformer Architecture: The specific type of neural network architecture that makes LLMs so effective. It allows the model to process sequences of data (like words in a sentence) and focus on the most important parts of the input.
Token: The smallest unit of text that an LLM can process. A word, a punctuation mark, or even a part of a word can be a token.
Parameters: The numerical values inside an LLM that determine its behaviour and knowledge. The number of parameters (often in the billions or trillions) is a key indicator of a model's complexity and power.
Fine-Tuning: The process of adapting a pre-trained LLM for a specific task or a more narrow domain by training it on a smaller, specialised dataset. This is how you would, for example, turn a general LLM into a customer service chatbot for a specific company.
Prompt: The input or instruction you give to an AI model to get a desired output. Crafting effective prompts is a skill known as prompt engineering.
Interacting with AI: Prompts, Outputs, and Data
To get the most out of AI, you need to understand how to communicate with it and what to expect in return.
Prompt Engineering: The art and science of writing effective prompts to get the best possible response from an AI model. This can involve providing context, examples, and specific constraints.
Context Window: The amount of information an LLM can "remember" or consider in a single conversation. A longer context window allows for more detailed and coherent multi-turn discussions.
Hallucination: When an AI model generates a confident but factually incorrect or nonsensical response. This is a significant challenge in AI and highlights the need for human oversight.
Bias: Errors in an AI model's output that stem from biases present in its training data. For example, if a model is trained on a dataset that under-represents certain demographics, its responses may perpetuate stereotypes.
Inference: The process of a trained AI model making a prediction or generating a new output based on new input data.
Latency: The time delay between giving a prompt and receiving a response from the AI.
Synthetic Data: Data that is artificially generated by an AI rather than collected from the real world. It can be used to train other AI models, especially when real data is scarce.
Types of AI and Learning Methods
AI isn't a monolith; it's a diverse field with many different approaches.
Artificial General Intelligence (AGI): A hypothetical type of AI that possesses a wide range of cognitive abilities, similar to human intelligence. It would be able to learn, reason, and adapt to any task, not just a specific one. This is a long-term goal of many researchers.
Supervised Learning: A machine learning method where the model is trained on a dataset that is already labelled with the correct answers. The model learns to map inputs to outputs.
Unsupervised Learning: A method where the model is given unlabeled data and must find patterns, structures, and relationships on its own.
Reinforcement Learning: A learning approach where an AI agent learns to make a sequence of decisions by interacting with an environment and receiving rewards or penalties for its actions.
Computer Vision: The field of AI that enables computers to "see" and interpret visual data from the world, such as images and videos.
Natural Language Processing (NLP): The branch of AI that focuses on enabling computers to understand, interpret, and generate human language. LLMs are a major advancement in NLP.
Technical and Ethical Considerations
The development of AI comes with important technical and ethical considerations.
Alignment: The process of ensuring an AI model's goals and values are aligned with human values. This is crucial for preventing unintended or harmful outcomes.
Ethical AI: A framework for developing and deploying AI in a way that is fair, transparent, and beneficial to society. This includes addressing issues of privacy, bias, and accountability.
Explainable AI (XAI): The effort to create AI models whose decision-making processes are understandable and transparent to humans. This is especially important in high-stakes applications like medicine or finance.
Open Source AI: AI models and tools where the underlying code and data are publicly available, allowing for widespread use, modification, and collaboration.
Guardrails: Safety mechanisms and policies put in place to ensure AI systems operate within defined ethical and legal boundaries.
Model: A synonym for an AI system that has been trained to perform a specific task. For instance, a language model generates text, while an image model creates pictures.
