πŸ’‘Prompt Engineering

Prompt engineering is the process of strategically formulating and refining prompts to elicit the most accurate and useful responses from AI, particularly large language models (LLMs). It involves understanding the AI's capabilities and structuring queries to guide the AI towards the desired output. In the video, Anu Kubo emphasizes the importance of prompt engineering in maximizing productivity with LLMs and improving interactions between humans and AI.

πŸ’‘Large Language Models (LLMs)

Large language models, or LLMs, are advanced AI systems designed to process and generate human-like text based on vast amounts of training data. They are capable of performing various language-related tasks, such as answering questions, summarizing texts, and even creating content. In the context of the video, LLMs like chat GPT are central to the discussion of prompt engineering strategies and their application.

πŸ’‘Zero-Shot Prompting

Zero-shot prompting is a technique where an AI model is asked to perform a task without being provided any specific examples of that task during the prompt. It relies on the model's pre-existing knowledge and understanding of language. The video illustrates this concept by asking the AI when Christmas is in America, expecting the model to use its general knowledge to answer the question.

πŸ’‘Few-Shot Prompting

Few-shot prompting enhances an AI model's performance on a task by providing it with a few examples during the prompt. This method allows the model to 'learn' from the examples and tailor its response more effectively. In the video, Anu Kubo demonstrates few-shot prompting by giving the AI examples of her favorite foods before asking for restaurant recommendations in Dubai.

πŸ’‘AI Hallucinations

AI hallucinations refer to the incorrect or imaginative outputs generated by AI models when they misinterpret or overinterpret data. This can occur when the AI fills in gaps in understanding with incorrect assumptions. The video uses the example of Google's Deep Dream to illustrate how AI hallucinations can produce unusual and sometimes humorous results, offering insight into the AI's thought processes.

πŸ’‘Text Embeddings

Text embeddings are a method in natural language processing where textual data is converted into numerical vectors that capture semantic meaning. These embeddings allow AI models to better understand and process language by representing words or phrases as points in a high-dimensional space. In the video, Anu Kubo discusses how text embeddings are used in prompt engineering to help AI models interpret and generate more accurate responses.

πŸ’‘Linguistics

Linguistics is the scientific study of language and its structure, including aspects such as phonetics, phonology, morphology, syntax, semantics, and pragmatics.
