Introduction to Artificial Intelligence

• Artificial Intelligence (AI) enables computers and machines to simulate human intelligence and problem-solving capabilities.

Definition of AI

• AI was defined by Stanford Professor John McCarthy in 1955 as “the science and engineering of making intelligent machines”.

Machine Learning (ML)

• ML provides machines the ability to automatically learn from data and past experiences to identify patterns and make predictions with minimal human intervention.

Natural Language Processing (NLP)

• NLP enables computers and digital devices to recognize, understand, and generate text and speech.
• NLP impacts daily life through search engines, chatbots, voice-operated GPS systems, and digital assistants on smartphones.

Computer Vision

• Computer vision is a field of AI that uses machine learning and neural networks to teach computers and systems to derive meaningful information from digital images, videos, and other visual inputs.
• Examples of computer vision technology include Google Lens, self-driving vehicles, mask detection technology, and exam proctoring services.

Large Language Models (LLMs)

• LLMs are a category of foundation models trained on immense amounts of data, making them capable of understanding and generating natural language and other types of content.
• LLMs represent a significant breakthrough in NLP and AI and are easily accessible to the public through interfaces like Open AI’s Chat GPT-3 and GPT-4, Meta’s Llama models, and Google Gemini.

Generative Pre-trained Transformers (GPT)

• GPTs are a type of LLM designed to understand and generate natural language content.
• GPT models, such as OpenAI's Chat GPT-3 and GPT-4, are known for their ability to generate coherent and contextually relevant text based on input.

Prompt Engineering

• Prompt Engineering is the practice of designing and refining input queries (prompts) to guide an AI model, like GPT-4, to generate the desired output.

Characteristics of Writing a Good Prompt

• Specificity and Clarity: provide clear and detailed instructions to minimize ambiguity and help the model understand exactly what is needed.
• Context Setting: include background information, define roles, and specify the desired tone and format.
• Format Specification: indicate the desired structure of the output (e.g., list, paragraph, essay, dialogue) and set length requirements.
• Providing Examples: use examples to guide the model towards the desired style or content and show desired output.
• Step-by-Step Instructions: break down complex queries into smaller, manageable steps and request sequential responses.

Applications of GPT Models

• Content Creation: generate articles, stories, poetry, and even code, aiding in creative processes and reducing the time needed for content development.
• Customer Service: power chatbots and virtual assistants, providing real-time assistance and customer support.
• Language Translation: translate languages, making communication across language barriers more accessible.
• Education: used as tutoring systems, offering personalized learning experiences and answering student queries.
• Research: summarize research papers, making it easier to digest complex information.
