Artificial intelligence (AI) is everywhere. From virtual assistants like Siri and Alexa to customer service chatbots to recommendation engines on your favorite streaming platforms, it’s a part of our daily lives. It’s also reshaping various industries, from healthcare to education to agriculture. Large language models (LLMs), in particular, are revolutionizing how many people learn and work. But what are LLMs, and how does a large language model work?

Our 2024 guide to LLMs aims to help readers learn large language models to better understand their capabilities. In this guide, we’ll discuss what these models are, how they work, and what their capabilities are, including understanding, generating content, and problem-solving. We’ll also reveal some data collection strategies that drive these algorithms to create content like humans would by feeding their knowledge, behavior, and abilities.

Large Language Model Meaning

Large language models (LLMs) refer to advanced AI models designed to understand, generate, and process human language at an enormous scale. These models, often based on deep learning techniques like transformer architectures, utilize massive amounts of data and computational power to learn patterns, relationships, and nuances within language.

LLMs excel in various language-related tasks such as:

• Generating text
• Answering questions
• Translating text
• Summarizing longer text works
• Analyzing sentiments

Large language models work by processing and learning from colossal datasets to develop contextual understanding, allowing them to generate coherent and contextually relevant text. These models continually evolve as we input more data, which allows their language comprehension and generation abilities to become increasingly sophisticated. Large language models have found applications in diverse fields, from improving search engines and virtual assistants to aiding content creation and automating tasks across industries.

Are large language models machine learning?

Large language models are a form of machine learning. They fall under the umbrella of AI, specifically under the broader category of natural language processing (NLP). LLMs utilize machine learning techniques, often using deep learning architectures like transformers, to process and understand language.

Large language model software learns patterns, relationships, and structures within language by analyzing vast amounts of text data. Through iterations and exposure to extensive datasets, they refine their ability to generate, comprehend, and manipulate language in various contexts.

The training process for large language models involves feeding them massive volumes of text data and adjusting their parameters using techniques like unsupervised learning. This allows the model to learn the statistical properties of language and develop the ability to generate coherent and contextually relevant text based on the patterns it has learned from the data.

In a 2023 study titled Larger language models do in-context learning differently, researchers found that the larger the language model, the more nuanced and contextually sensitive its in-context learning becomes. These larger models showed improved comprehension and generation abilities when performing NLP tasks.

Are large language models generative AI?

Large language models belong under the generative AI category. These models possess the capability to generate human-like text. They do this based on the patterns and structures they learn by absorbing extensive datasets during their training.

Generative AI refers to artificial intelligence systems that create new content, whether it’s text, images, music, or other forms, that is original and not directly copied from the input data. LLMs, such as Generative Pre-trained Transformer (GPT) models like ChatGPT, demonstrate their generative capabilities by creating coherent and contextually relevant text based on the prompts or cues we give them.

When we prompt them with a sentence or phrase, large language models generate responses or continuations that are novel and can resemble human-written text. The generative nature of large language models allows them to perform tasks such as task completion, summarization, story generation, and more. These abilities make LLMs valuable tools in various applications that require creative language generation.

How Do Large Language Models Learn?

Large language models (LLMs) learn through a process called unsupervised learning using large amounts of mainly text data. They use transformer architectures, like the GPT models, which consist of layers of neural networks designed to process sequential data, such as language.

During their training phase, developers expose large language models to vast datasets from diverse sources like books, articles, websites, and more. They learn the statistical patterns, relationships, and nuances within this data, which allows them to build an understanding of language structures, semantics, and context.

Transfer learning from large language models

Transfer learning (TL) involves using knowledge gained from one task or domain to improve learning or performance in another related or different area. It’s like applying previously learned information to new but similar situations to enhance understanding or skill in a more efficient manner.

Transfer learning plays an important role in LLM training. Initially, large language models are pre-trained on a large and diverse dataset in an unsupervised training stage. This phase involves learning general language patterns and information without specific task-oriented guidance. Once they are pre-trained, LLMs undergo specific task-oriented training on smaller, specialized datasets that relate to particular tasks, such as translation, summarization, or answering questions. This fine-tuning process allows large language models to adapt their learned knowledge to excel in specific tasks using the generalized knowledge they gained during pre-training.

Transfer learning from large language models enables quicker and more effective learning in specialized tasks, as these models already possess a broad understanding of language from their pre-training phase. This approach minimizes the need for extensive training on smaller datasets for each individual task, making the models more adaptable and efficient in various real-world applications.

Large language models and differential privacy

Differential privacy is a privacy-preserving concept that aims to protect individual data points in a dataset while still allowing for meaningful analysis. When training large language models, researchers can apply the differential privacy framework to mitigate the risk of exposing sensitive information that may be present in the training data. The goal is to train the model in a way that protects sensitive data by preventing the model from memorizing specific details within individual data points.

Let’s break down how differential privacy applies to training LLMs.

• Noise injection. During the training process, researchers calculate gradients for each training example. Gradients represent the direction and magnitude of changes they need to make to update the model’s parameters for better performance. They then inject noise, which means random variation, into these gradients. Instead of using the exact gradients they calculated from the data, the model uses perturbed gradients.
• Noisy gradient aggregation. The researchers aggregate the noisy gradients from individual training examples to update the model’s parameters. This aggregation helps prevent any single training example from overly influencing the model.
• Privacy budget. Differential privacy introduces the concept of a “privacy budget,” which quantifies the level of privacy protection. A smaller privacy budget provides stronger privacy guarantees. Researchers can fine-tune the privacy level by adjusting such parameters as the amount of noise they add to the gradients and the overall privacy budget.
• Post-processing. After training, researchers may opt to apply additional privacy-preserving techniques. For example, they can add noise to the model’s final outputs.
• Model architecture. Developers can design the architecture of the model itself to minimize the risk of learning too specifically from sensitive details in the training data.
