Advanced Prompt Eng

- Zero-shot prompt: ​This type of prompt instructs an LLM to perform ​a task without any prior specific training or examples. ​Here, the LLM is asked to ​classify a statement as true or false. ​The Eiffel Tower is located in Berlin. 
​Then the model gives the response. ​This task requires the LLM to understand the context ​and information without any previous tuning ​for the specific query. ​A one-shot prompt gives the LLM ​a single example to help it perform a similar task. ​For example, how is the weather today? ​The LLM shows how to ​translate a sentence from English to French. ​This serves as a template. ​Then it's given a new sentence, ​where is the nearest supermarket, ​and is expected to translate it ​into French using the learned format. ​The AI uses the initial example ​to correctly perform the new translation. 

- Few-shot prompting: where the AI ​learns from a small set of ​examples before tackling a similar task. ​This helps the AI generalize ​from a few instances to new data. ​For example, the LLM is shown three statements, ​each labeled with an emotion. ​These examples teach the LLM to ​classify emotions based on context. ​Then it classifies a new statement. ​That movie was so scary. 
​I had to cover my eyes. ​The LLM will output the emotion.

- ​Chain-of-thought or COT prompting is ​a technique used to guide ​LLM through complex reasoning step-by-step. ​This method is highly effective for problems requiring ​multiple intermediate steps or ​reasoning that mimics human thought processes. ​The example shows how ​CoT prompting is applied to an arithmetic problem. ​The prompt asks the model to consider the problem of ​a store that initially had 22 apples, ​sold 15, and then ​received a new delivery of eight apples. ​The task is to determine how many apples there are now. 
​You can view the model output for the CoT prompt query ​by breaking down the calculation ​into clear sequential steps. ​The model arrives at ​the correct answer and provides ​a transparent explanation. 

- ​Self-consistency is a technique for ​enhancing the reliability and accuracy of outputs. ​It involves generating multiple independent answers to ​the same question and then evaluating ​these to determine the most consistent result. ​In this example, you see ​a problem involving age calculation. ​The query is, when I was six, ​my sister was half my age. ​Now I am 70. What age is my sister? 
​The model is prompted to produce ​three independent calculations and ​explanations to ensure accuracy. ​You can view the model outputs with ​three different ways of calculation ​and determine a consistent answer. ​This approach demonstrates how ​self-consistency can verify the reliability of ​the responses from LLMs by ​cross-verifying multiple paths to the same answer. 

- ​Certain tools can facilitate interactions with LLMs, ​such as OpenAI's Playground, LangChain, ​Hugging Face's Model Hub, ​and IBM's AI Classroom. ​They allow you to develop, ​experiment with, evaluate, and deploy prompt. ​They enable real-time tweaking and testing of ​prompt to see immediate effect on outputs.
​Moreover, they provide access to ​various pre-trained models suitable ​for different tasks and languages. ​They also facilitate ​the sharing and collaborative editing ​of prompts among teams or communities. ​Finally, they offer tools to track changes, ​analyze results, and optimize ​prompt based on performance metrics.

- ​LangChain uses prompt templates, ​predefined recipes for generating ​effective prompt for LLMs. ​These templates include ​instructions for the language model, ​a few-shot examples to help the model ​understand contexts and expected responses, ​and a specific question directed at the language model. ​Here is a code snippet to ​apply a prompt template from LangChain.
