With the emergence of NLP-based AI models, the niche of prompt engineering has gained huge prominence that bridges the gap between human communication and machine comprehension. Prompt engineering is referred to as the practice of designing and formulating effective prompts or instructions to interact with language models like GPT-3.5 to obtain desired outputs. It involves crafting input text that guides the model to produce the desired responses, whether those responses are generating coherent text, answering questions, providing explanations, or even performing more complex tasks like code generation or translation.
Uses of prompt engineering
Text generation: You can use prompt engineering to generate human-like text serving diverse purposes, such as content creation, creative writing, story generation, and more.
Question answering: By crafting well-structured prompts, you can use the model to answer specific questions by extracting relevant information from its vast knowledge base.
Code generation: You can instruct the model to generate code snippets in different programming languages for specific tasks.
Translation: Prompt engineering can be employed to translate text from one language to another accurately.
Summarization: Models can be guided to summarize long articles or documents using carefully crafted prompts.
Conversational agents: Developing conversational agents with specific personalities or styles of communication can be achieved through prompt engineering.
Prompt engineering techniques
Prompt engineering, a rapidly evolving research area, employs novel techniques to enhance language model performance. These techniques offer diverse ways to instruct and shape AI models, showcasing the versatility of prompt engineering. Here are some impactful methods:
N-shot prompting
This technique provides N examples or cues to guide a model’s predictions. Zero-shot prompting requires no additional examples, suitable for classification, translation, and text generation. Few-shot prompting extends this with a limited number of examples for improved accuracy.
Chain-of-thought (CoT) prompting
Chain-of-thought (CoT) prompting facilitates multi-stage reasoning by guiding models to express intermediate steps. This technique has given rise to adaptations like self-consistency, Least-to-most (LtM), and active prompting.
- Self-consistency prompting: This variation involves constructing diverse paths of reasoning and selecting answers that exhibit maximum consistency. This approach ensures heightened response precision and reliability by leveraging a consensus-based mechanism.
- Least-to-most prompting (LtM): LtM employs a sequential breakdown of problems into less complex sub-problems. The model solves them in order, with each subsequent sub-problem utilizing solutions from previously addressed ones.
- Active prompting: Expanding the CoT approach to a larger scale, active prompting identifies pivotal questions for human annotation. The model initially assesses uncertainty within its predictions and selects questions with the highest uncertainty. These questions undergo human annotation and are subsequently integrated into a CoT prompt.
Generated knowledge prompting
Generated knowledge prompting harnesses the substantial capacity of large language models to generate potentially valuable information linked to a given prompt. The fundamental idea is to encourage the language model to provide supplementary knowledge. This additional knowledge is then employed to craft a final response that is more precise, well-informed, and contextually grounded.
Directional stimulus prompting
Directional stimulus prompting stands as an advanced method within the realm of prompt engineering. Its primary objective is to guide the response of a language model in a precise direction. This technique proves especially valuable when aiming to obtain an output that adheres to specific criteria such as format, structure, or tone. By employing directional stimulus prompting, one can exercise greater control over the nature of the generated output, ensuring it aligns with the desired attributes.
ReAct prompting
ReAct prompting draws inspiration from the human approach to acquiring new skills and making decisions—a fusion of “reasoning” and “acting.” This innovative technique aims to overcome the shortcomings of methods like Chain-of-thought (CoT) prompting. While CoT excels in producing plausible answers across tasks, it is hampered by challenges such as fact hallucination and error propagation due to its limited interaction with external environments and inability to update its knowledge.
Multimodal CoT prompting
Multimodal CoT prompting is a natural evolution of the original CoT technique, encompassing diverse data modes, commonly text and images. With this approach, extensive language models can harness visual information alongside text. This synergy enables the model to yield responses that are not only more precise but also steeped in contextual relevance.
Graph prompting
Graph prompting is a strategic approach that capitalizes on a graph’s structure and content to guide a large language model. In this technique, a graph is harnessed as the primary source of information. The key lies in translating the graph’s content into a format that the language model can effectively comprehend and process.
