Exploring Language Models and Prompt Engineering in AI Projects

This video discusses the setup of a large language model in Google Colab and explores different search methods and prompt engineering techniques for AI models. It also covers zero-shot and few-shot prompting and the concept of prompt injection.

00:00:00 This video discusses setting up a large language model in Google Colab and downloading a pre-trained model for machine learning projects.

🤖 Machine learning includes chat gbt gpt4 and a large language model called Bloom.

🔗 Setting up a large language model in Google collab involves installing libraries and downloading a pre-trained model.

💡 There are three different ways to generate text using the language model: greedy search, beam search, and sampling.

00:03:05 LLM Projects: Exploring different search methods for AI learning models and their effectiveness in answering questions. Greedy search, beam search, and sampling top K and top P are discussed.

🔍 There are three different ways to use LLM: greedy search, beam search, and sampling top K and top P.

Greedy search produces poor results, often repeating phrases and not answering the question effectively.

Beam search is a better alternative to greedy search, but its functionality is not clearly understood.

🎲 Sampling top K and top P is the most powerful method, providing optimal levels of randomness for better results.

💡 The quality of results in LLM depends heavily on the prompt given, and better prompts can improve performance.

💡 Google's AI, Bard, demonstrates better understanding and provides sensible scientific answers.

00:06:10 This video explores prompt engineering in AI text generation models and the different techniques used to improve prompt quality and accuracy.

📚 Prompt engineering guide teaches techniques for writing better prompts.

🔍 Different search techniques are used to determine sentiment from text.

🤔 Sampling top K and top p technique fails to determine sentiment accurately.

00:09:23 This video discusses different techniques for zero-shot prompting and few-shot prompting in AI models.

🤖 There are different ways to prompt AI models, such as zero-shot prompting and few-shot prompting.

🎥 Providing examples to AI models can yield accurate results, even if the examples are not logically correct.

🔍 Different search methods, such as greedy search and beam search, can affect the performance of AI models.

00:12:28 LLM Projects. Word matching, math, logic questions, pattern recognition. The AI struggles with reasoning but performs better with examples. Prime numbers are involved.

🔑 The AI model is focused on word matching and lacks reasoning abilities.

📊 The AI model struggles with logic and pattern recognition tasks.

🔢 The AI model fails to identify the pattern of prime numbers in a sequence.

00:15:33 The video discusses prompt engineering and demonstrates solving math problems using different models. It also introduces a prompt injection attack.

📚 Prompt engineering is an important discipline that involves creating effective prompts to solve problems.

🔢 The task involves solving math problems, such as calculating the total number of pencils or people in a given scenario.

💻 The video also mentions a prompt injection attack, which is similar to command injection.

00:18:37 LLM Projects: Understanding the concept of prompt injection and the importance of crafting precise questions for accurate AI responses.

📚 Using prompt injection to change the logic and understanding of models.

💡 Larger models perform better but require more memory.

👶 Explaining the concept of ignoring directions to a child.

🎯 Importance of crafting well-formed questions for useful AI responses.
