Artificial intelligence is a deep and convoluted world. The scientists who work in this field often rely on jargon and lingo to explain what they\u2019re working on. As a result, we frequently have to use those technical terms in our coverage of the artificial intelligence industry. That\u2019s why we thought it would be helpful to put together a glossary with definitions of some of the most important words and phrases that we use in our articles.<\/p>\n

We will regularly update this glossary to add new entries as researchers continually uncover novel methods to push the frontier of artificial intelligence while identifying emerging safety risks.<\/p>\n

An AI agent refers to a tool that makes use of AI technologies to perform a series<\/a> of tasks on your behalf \u2014 beyond what a more basic AI chatbot could do \u2014 such as filing expenses, booking tickets or a table at a restaurant, or even writing and maintaining code. However, as we\u2019ve explained before, there are lots of moving pieces in this emergent space, so different people can mean different things when they refer to an AI agent. Infrastructure is also still being built out to deliver on envisaged capabilities. But the basic concept implies an autonomous system that may draw on multiple AI systems to carry out multi-step tasks.<\/p>\n

Given a simple question, a human brain can answer without even thinking too much about it \u2014 things like \u201cwhich animal is taller between a giraffe and a cat?\u201d But in many cases, you often need a pen and paper to come up with the right answer because there are intermedia<\/a>ry steps. For instance, if a farmer has chickens and cows, and together they have 40 heads and 120 legs, you might need to write down a simple equation to come up with the answer (20 chickens and 20 cows).<\/p>\n

In an AI context, chain-of-thought reasoning for large language models means breaking down a problem into smaller, intermediate steps to improve the quality of the end result. It usually takes longer to get an answer, but the answer is more likely to be right, especially in a logic or coding context. So-called reasoning models are developed from traditional large language models and optimized for chain-of-thought thinking thanks to reinforcement learning.<\/p>\n

(See: Large language model<\/a>)<\/p>\n

A subset of self-improving machine learning in which AI algorithms are designed with a multi-layered, artificial neural network (ANN) structure. This allows them to make more complex correlations compared to simpler machine learning-based systems, such as linear models or decision trees. The structure of deep learning algorithms draws inspiration from the interconnected pathways of neurons in the human brain.<\/p>\n

Deep learning AIs are able to identify important characteristics in data themselves, rather than requiring human engineers to define these features. The structure also supports algorithms that can learn from errors and, through a process of repetition and adjustment, improve their own outputs. However, deep learning systems require a lot of data points to yield good results (millions or more). It also typically takes longer to train deep learning vs. simpler machine learning algorithms \u2014 so development costs tend to be higher.<\/p>\n

(See: Neural network<\/a>)<\/p>\n

This means further training of an AI model that\u2019s intended to optimize performance for a more specific task or area than was previously a focal point of its training \u2014 typically by feeding in new, specialized (i.e. task-oriented) data.\u00a0<\/p>\n

Many AI startups are taking large language models as a starting point to build a commercial product but vying to amp up utility for a target sector or task by supplementing earlier training cycles with fine-tuning based on their own domain-specific knowledge and expertise.<\/p>\n

(See: Large language model (LLM)<\/a>)<\/p>\n

Large language models, or LLMs, are the AI models used by popular AI assistants, such as ChatGPT, Claude, Google\u2019s Gemini, Meta\u2019s AI Llama, Microsoft Copilot, or Mistral\u2019s Le Chat. When you chat with an AI assistant, you interact with a large language model that processes your request directly or with the help of different available tools, such as web browsing or code interpreters.<\/p>\n

AI assistants and LLMs can have different names. For instance, GPT is OpenAI\u2019s large language model and ChatGPT is the AI assistant product.<\/p>\n

LLMs are deep neural networks made of billions of numerical parameters (or weights, see below<\/a>) that learn the relationships between words and phrases and create a representation of language, a sort of multidimensional map of words.<\/p>\n

Those are created from encoding the patterns they find in billions of books, articles, and transcript<\/a>s. When you prompt an LLM, the model generates the most likely pattern that fits the prompt. It then evaluates the most probable next word after the last one based on what was said before. Repeat, repeat, and repeat.<\/p>\n

(See: Neural network<\/a>)<\/p>\n

Neural network refers to the multi-layered algorithmic structure that underpins deep learning \u2014 and, more broadly, the whole boom in generative AI tools following the emergence of large language models.\u00a0<\/p>\n

Although the idea to take inspiration from the densely interconnected pathways of the human brain as a design structure for data processing algorithms dates all the way back to the 1940s, it was the much more recent rise of graphical processing hardware (GPUs) \u2014 via the video game<\/a> industry \u2014 that really unlocked the power of theory. These chips proved well suited to training algorithms with many more layers than was possible in earlier epochs \u2014 enabling neural network-based AI systems to achieve far better performance across many domains, whether for voice recognition, autonomous navigation, or drug discovery.<\/p>\n

(See: Large language model (LLM)<\/a>)<\/p>\n

Weights are core to AI training as they determine how much importance (or weight) is given to different features (or input variables) in the data used for training the system \u2014 thereby shaping the AI model\u2019s output.\u00a0<\/p>\n

Put another way, weights are numerical parameters that define what\u2019s most salient in a data set for the given training task. They achieve their function by applying multiplication to inputs. Model training typically begins with weights that are randomly assigned, but as the process unfolds, the weights adjust as the model seeks to arrive at an output that more closely matches the target.<\/p>\n

For example, an AI model for predicting house prices that\u2019s trained on historical real estate data for a target location could include weights for features such as the number of bedrooms and bathrooms, whether a property is detached, semi-detached, if it has or doesn\u2019t have parking, a garage, and so on.\u00a0<\/p>\n

Ultimately, the weights the model attaches to each of these inputs is a reflection of how much they influence the value of a property, based on the given data set.<\/p>\n<\/div>\n
