What is artificial intelligence (AI) and how does machine learning relate to it?

Artificial intelligence refers to computer programs designed to perform cognitive tasks typically associated with human intelligence, such as understanding language, problem-solving, and decision-making. Machine learning is a subset of AI focused on developing computer programs that can analyse data to make decisions or predictions without being explicitly programmed. These programs learn from data, identifying patterns and improving their performance over time, as illustrated by the example of a program learning to distinguish between ripe and unripe apples by analysing numerous examples.

What is generative AI and what is an example of a widely used type?

Generative AI is a type of artificial intelligence that can generate new content, such as text, images, or other media. A popular example of generative AI is a large language model (LLM), which can process and output text. Google's Gemini is given as an example of an LLM, capable of tasks like writing emails, brainstorming ideas, summarising information, and even simulating conversations.

How do users typically interact with AI models and why is "prompt engineering" important?

The primary way users interact with most AI models and tools is through prompting, which involves providing text input that gives instructions to the AI on how to generate an output. While basic prompting is straightforward, the quality of the results obtained can vary significantly depending on how well the prompt is crafted. This is why prompt engineering, the art of designing effective prompts to achieve desired outcomes, is crucial. Well-designed prompts with clarity, specificity, and context can dramatically improve the usefulness and accuracy of AI-generated responses.

What is the "human in the loop" approach to using AI and why is it recommended?

The "human in the loop" approach advocates for human involvement throughout the process of interacting with AI. Instead of solely relying on AI-generated outputs, humans should actively participate by providing input, reviewing suggestions, making adjustments, and ultimately having the final say. This approach is recommended because AI, despite its advancements, is not perfect and can have limitations such as knowledge cut-offs and the tendency to "hallucinate" (output false information). Human oversight helps to mitigate risks, ensure accuracy, and prevent potentially harmful consequences, particularly in high-stakes situations like medical diagnoses.

What are "knowledge cut-off" and "hallucinations" in the context of AI, and why are they important to be aware of?

An AI model's knowledge cut-off refers to the point in time after which the AI has not been trained and therefore has no information about events or developments. Hallucinations occur when an AI outputs information that is factually incorrect or nonsensical. It's vital to be aware of these limitations because AI may present fabricated information as truth, which can be misleading or even harmful. Users should be critical of AI outputs and cross-reference information, especially when dealing with sensitive topics.

What are some key techniques for effective prompt engineering discussed in the course?

Several techniques for effective prompt engineering are highlighted, including:
* Providing clear and specific prompts with relevant context.
* Considering the verb used in the prompt to guide the AI's action (e.g., "summarise," "classify," "extract," "create").
* Thinking about the desired output format and explicitly requesting it (e.g., a bulleted list or a table with specific columns).
* Using an iterative approach, starting with simple prompts and gradually refining them based on the AI's output.
* Employing "shot" prompting: zero-shot (asking without examples), one-shot (providing one example), and few-shot (providing multiple examples) to guide the AI, especially for nuanced requests.
* Utilising "Chain of Thought" prompting for complex tasks by breaking them down into a series of subtasks with step-by-step instructions and examples.

What are some potential harms associated with AI, and what measures can be taken to mitigate them?

The course discusses various potential harms caused by AI tools, often stemming from biased outputs. These include "quality of service harm," where AI performs poorly for certain groups (e.g., speech recognition struggling with individuals with disabilities), and "representation harm," where AI reinforces societal biases (e.g., automatically assigning genders to professions). Mitigation strategies include ensuring diverse representation in the development of AI tools and continuously collecting feedback from a wide range of users to identify and address biases. The importance of AI safety as a growing field is also emphasised.

What is the main message of the module on responsible AI use?

The primary takeaway from the responsible AI use module is the critical understanding that AI tools can cause various harms, predominantly due to biased outputs.

The module stresses the importance of considering ethical implications and striving for fairness and equity in the development and deployment of AI technologies.

What is the fundamental difference between artificial intelligence and machine learning?

Artificial intelligence (AI) refers to computer programs that can complete cognitive tasks typically associated with human intelligence, while machine learning (ML) is a subset of AI where computer programs analyse data to make decisions or predictions. AI is the broader field, and ML is a key technique used to power many AI applications.

What is "zero-shot prompting" and when might it be sufficient?

Zero-shot prompting involves asking an AI to perform a task without providing any specific examples of the desired input-output format. It might be sufficient for very simple and straightforward requests where the AI has a strong general understanding of the task.

What is "few-shot prompting" and why can it be effective for large language models?

Few-shot prompting is a technique where you provide the AI with a few examples of the desired input and output. This can be very effective for large language models because they are good at recognising patterns and can mimic the style and format of the examples to generate relevant responses without explicit detailed instructions.

What is "Chain of Thought" prompting, and in what type of situation is it particularly helpful?

Chain of Thought prompting involves asking a large language model to break down a complex task into a series of smaller, logical subtasks to arrive at a final answer. It is particularly helpful when dealing with problems that require complex reasoning or multiple steps to solve.

What is "quality of service harm" in the context of responsible AI and provide an example?

Quality of service harm occurs when AI tools do not perform as well for certain groups of people, often due to biases in the training data. An example is when early speech recognition technology was less effective at understanding individuals with disabilities because the training data lacked sufficient examples of their speech patterns.

Why is increased representation in the development of AI tools important for responsible AI?

Increased representation in the development of AI tools is crucial because it helps to identify and mitigate biases in the data and algorithms that can lead to harmful outputs. Diverse perspectives in the development process can lead to more inclusive and fair AI systems, ensuring that AI tools perform equitably across different demographic groups.
