HOW  NLP vs. LLM Work?

What is NLP?

Natural Language Processing (NLP) is a field of computer science and artificial intelligence that focuses on enabling computers to understand, interpret, and generate human language.

NLP involves using computational techniques, such as statistics, machine learning, and deep learning, to process and analyze natural language data such as text and speech. It goes beyond the dictionary definition of words. It considers grammar, sentence structure (syntax), and the deeper meaning (semantics) behind the language.

It allows computers to analyze text and extract information. For example, a computer reading a news article and summarizing the key points—that’s the power of NLP.

NLP enables computers to perform various tasks, such as translating languages, identifying emotions in written text (sentiment analysis), or classifying documents based on their content. In essence, IT equips computers with the essential skills to bridge the gap between human and computer communication. It’s the building block that allows more advanced applications like LLMs (Large Language Models) to flourish.

NLP vs LLM deal with human language and are valuable in language-related AI tasks, but they take different approaches to achieving their goals.

Think of NLP as a carpenter with a toolbox of specialized instruments—a hammer for grammar, a saw for syntax, and so on. LLMs, on the other hand, are like powerful 3D printers that can use sophisticated algorithms to take raw materials (text data) and create intricate structures (human-like text).

In other words, NLP provides the foundation for understanding language, while LLMs build upon that foundation to generate creative and informative responses. Together, they push the boundaries of human-computer interaction.

NLP: Rule-Based and Statistical Techniques

It relies on a combination of techniques to enable the generation of human language. It is mostly used for spell-checking and auto-correction.

1- Rule-based systems

Traditional NLP methods rely on pre-defined rules for tasks like part-of-speech tagging (identifying nouns, verbs, etc.) or named entity recognition (finding names of people, places, and organizations). Think of these rules as a set of instructions for the computer to follow.

2- Statistical Techniques

These involve training models on labeled data. For example, a sentiment analysis model might be trained on reviews with positive or negative labels to learn how to identify sentiment in new text. They offer more flexibility than rule-based systems but require larger datasets for training.

What is LLM?

LLM stands for Large Language Model. They are trained on massive amounts of text data, allowing them to go beyond basic understanding and delve into the nuances of language. Unlike NLP, which focuses on specific tasks, LLMs excel at generating human-quality text.

They can write creative content, answer your questions in an informative way, and even translate languages with a focus on fluency rather than just accuracy provides the building blocks for understanding language, while LLMs employ those blocks to construct complex and creative structures with human-like fluency. Thus, they are a powerful tool pushing the boundaries of human-computer interaction.

Further, LLM can handle a wide range of tasks, from summarizing a text to writing different kinds of creative content and answering your questions, even open-ended ones, in an informative way.
