The ultimate A-Z guide to generative AI terminology 

 

 

A comprehensive AI glossary designed specifically for founders, makers, product people, and marketers — with or without a technical background.

Artificial intelligence (AI) has rapidly evolved over the past decade, paving the way for an ever-increasing array of applications and innovations. As a result, a wealth of complex terms, concepts, and technologies has emerged, making it challenging for even the most technically-minded individuals to keep up with the latest advancements.

 

To facilitate a deeper understanding of generative AI and its various components, this comprehensive A-Z glossary has been designed specifically for founders, makers, product people, and marketers with or without a technical background.

 

This glossary aims to cover essential terminology associated with generative AI, offering concise and informative explanations that cater to both novice and experienced professionals. Each term is explained in two ways: 1) in simple terms that a 16-year-old could understand, and 2) in a more technical manner suitable for software developers. By exploring the intricacies of these terms, you'll gain a solid foundation to navigate the vast and rapidly evolving AI landscape confidently.

U. Unsupervised Learning, Underfitting, and Universal Approximation Theorem

 

Unsupervised Learning

 

• 16-year-old: Unsupervised learning is a type of AI where the system learns by finding patterns in data without being given specific examples or answers. It's like discovering the structure of a puzzle without knowing what the final image should look like.
• Developer: Unsupervised learning is a machine learning paradigm that seeks to discover hidden patterns, structures, or relationships in unlabeled data, using techniques such as clustering, dimensionality reduction, or density estimation.

Underfitting

 

• 16-year-old: Underfitting happens when an AI system doesn't learn enough from its training data, making it too simple and less accurate. It's like not studying enough for a test and not understanding the concepts well enough to answer the questions.
• Developer: Underfitting is a phenomenon in machine learning where a model fails to capture the underlying structure or complexity of the training data, resulting in poor performance on both training and unseen data due to oversimplification or insufficient model capacity.

Universal Approximation Theorem

 

• 16-year-old: The Universal Approximation Theorem says that some types of AI systems, like neural networks, can learn to approximate any function or pattern, no matter how complicated it is, as long as they have enough layers or neurons.
• Developer: The Universal Approximation Theorem states that feedforward artificial neural networks with a single hidden layer and a finite number of neurons, using nonlinear activation functions, are capable of approximating any continuous function on compact subsets of R^n, given sufficient network complexity.

Validation

 

• 16-year-old: Validation is a way to test how well an AI system works by checking its predictions or decisions against a separate set of data that it hasn't seen before. It helps make sure the system is accurate and not just memorizing the training data.

XOR Problem

 

• 16-year-old: The XOR problem is a challenge that shows the limits of some simple AI systems. It's about teaching an AI to understand an exclusive or (XOR) operation, which can be tricky because it requires the AI to consider more than one input at a time.
• Developer: The XOR problem highlights the limitations of linear models and single-layer perceptrons in solving non-linearly separable tasks, such as the exclusive or (XOR) operation, which led to the development of multi-layer neural networks and backpropagation for more complex problem-solving.

YOLO (You Only Look Once)

 

• 16-year-old: YOLO is a super-fast way for AI systems to recognize and locate objects in images or videos by looking at the whole picture at once, instead of scanning it bit by bit. It's used in tasks like self-driving cars or security cameras to detect people and objects in real-time.

Z. Zero-Shot Learning, Z-score, and Zone of Proximal Development

 

Zero-Shot Learning

 

• 16-year-old: Zero-shot learning is a way for AI systems to recognize new things they've never seen before by using the knowledge they've learned from other tasks. It's like being able to identify a new animal just by knowing its features, even if you've never seen one before.
• Developer: Zero-shot learning is a machine learning paradigm that aims to classify or recognize novel categories or instances without any training examples, leveraging semantic information or relationships between known and unknown classes, often represented as attribute vectors or knowledge graphs.

Z-score

 

• 16-year-old: A Z-score is a way to measure how far a data point is from the average, in terms of standard deviations. It's used in AI systems to help identify unusual data points or to make sure data is on the same scale when comparing different things.
• Developer: Z-score, also known as standard score, is a statistical measure that describes a data point's relative distance from the mean of a distribution, expressed in terms of standard deviations. In machine learning, Z-scores are often used for data normalization, outlier detection, and feature scaling.

Zone of Proximal Development

 

• 16-year-old: The Zone of Proximal Development is an idea from psychology that says people learn best when they're challenged but not overwhelmed. In AI, this concept can be applied to make systems learn more effectively by giving them tasks that are just hard enough.
• Developer: The Zone of Proximal Development, originally introduced by psychologist Lev Vygotsky, refers to the range of tasks that are beyond an individual's current abilities but can be learned with guidance or collaboration. In AI and machine learning, this concept can inspire curriculum learning, where models are trained on progressively more challenging tasks to improve overall learning efficiency.
