Prompt engineering refers to the process of designing and constructing effective prompts or input sequences for text-based neural networks. In other words, it is the art of crafting the right input text to generate a desired output from a language model.

Text-based neural networks, such as GPT (Generative Pre-trained Transformer) models, are pre-trained on large corpora of text data and fine-tuned on specific tasks such as language translation, sentiment analysis, or question answering. However, for these models to generate accurate and relevant output, the input text prompt must be carefully crafted to provide sufficient context and information for the model to generate the desired output.

Prompt engineering involves selecting the right length of the prompt, the right type of prompt (such as questions, keywords, or descriptions), and including the right amount of relevant information in the prompt to guide the model towards the desired output. This process can be complex and iterative, as it often involves testing and tweaking different prompts to optimize the performance of the model.

Effective prompt engineering can significantly improve the performance of text-based neural networks and is a critical component of natural language processing tasks such as text generation, summarization, and dialogue systems.
