Below, we demystify the world of AI by breaking down the key terminologies and simplifying their definitions. Increasing your understanding of AI terminology will give you a better grasp of how AI functions and equip you to navigate discussions, developments and innovations within your organization.

General AI concepts

There are three general concepts that form the foundation of modern AI systems and are essential for understanding the capabilities, limitations and potential applications of AI technology. These three are:

Artificial intelligence (AI):

Artificial intelligence (AI) is a broad field of computer science focused on creating systems or machines that can perform tasks that would typically require human intelligence. These tasks include understanding natural language, recognizing patterns, making decisions and learning from experience.

As you delve into the world of AI, you may encounter terms like "generative AI" and "traditional AI." Traditional AI uses predetermined rules and algorithms to complete specific tasks, such as analyzing data and drawing conclusions (for example, the recommendations Netflix makes for you based on your streaming history, or a computer program that makes medical diagnoses based on x-rays).

Generative AI goes a step further by actually creating new content (copy, imagery and more) by learning from data patterns and answering prompts; well-known generative AI programs include ChatGPT, Bard and Midjourney.

Types of content

AI systems process different types of content, each with a unique organizational model. Understanding these formats is key to understanding how AI interacts with enterprise data.

Structured content

Structured content is highly organized data that fits into a fixed format. It typically resides in databases or spreadsheets, where each data point has a predefined location, making it easy to process.

Semi-structured content

Semi-structured content contains some organizational elements but does not follow a rigid data model. Examples include emails and invoices, which have predictable fields alongside free-form text.

Unstructured content

Unstructured content is information that lacks a predefined data model or organizational structure. It represents the majority of enterprise content, including documents, videos, images and audio files.

Machine Learning (ML)

Each type of ML provides a different approach to performing tasks and solving problems, allowing for a wide range of applications across different fields.

Let’s look into the different types of ML and how they help businesses achieve their goals:

Supervised learning (SL)

Supervised learning involves algorithms learning from labeled data, where training examples already contain correct answers.

The algorithm receives input-output pairs, then learns to map input to output, aiming for accurate predictions with new, unseen data.

Self-supervised learning (SSL)

Self-supervised learning is a technique where a model learns to make predictions about certain parts of the input data using the other parts as context.

This involves training the model to predict missing words within a text based on the surrounding context, essentially learning from the data itself without explicit human annotations.

Unsupervised learning (UL)

Unsupervised learning utilizes unlabeled data, lacking corresponding output labels for training.

Instead, the algorithm seeks to uncover hidden patterns, structures or relationships within the dataset by clustering similar points together to simplify its representation.

Reinforcement learning (RL)

In reinforcement learning, an agent learns to make sequential decisions through interactions with the environment, aiming to maximize a cumulative reward signal.

Unlike supervised and unsupervised learning, reinforcement learning is based on learning through trial and error by taking actions in the environment, observing the resulting rewards and adjusting behavior to achieve long-term goals.

Modeling concepts

Modeling concepts serve as the bedrock for predictive analytics and insightful decision-making. Understanding these three concepts is pivotal in understanding the meaning behind data-driven modeling:

Algorithm

An algorithm is a set of step-by-step instructions or rules designed to solve a specific problem or perform a particular task.

In the context of ML and data science, algorithms are used to train models and make predictions based on input data.

Neural network

A neural network is a computational model inspired by the structure and function of the human brain.

It consists of an interconnected network of artificial neurons organized into layers, including an input layer, one or more hidden layers and an output layer.

Overfitting

Overfitting occurs when a ML model learns to capture noise or random fluctuations in the training data rather than the underlying patterns or relationships.

This phenomenon occurs when a model becomes too complex or flexible relative to the amount of training data available, resulting in the model fitting the training data extremely well but performing poorly on new data points.

Evaluation metrics

Evaluation metrics are vital tools for assessing model performance. From accuracy to precision and recall, understanding these metrics is key to making informed decisions and driving progress. Let’s unpack the types of evaluation metrics:

Accuracy

Accuracy is calculated as the ratio of the number of correct predictions to the total number of predictions made by the model.

While accuracy provides a general overview of the model's performance, it may not be suitable for imbalanced datasets, where the classes are not represented equally.

Precision

Also known as positive predictive value, precision measures the proportion of true positive predictions out of all positive predictions made by the model.

Precision is particularly useful when the cost of false positives is high, and it complements accuracy by providing insights into the model's ability to avoid false positive predictions.

Recall

Recall focuses on the ability of the model to correctly identify all positive instances, regardless of the number of false negatives.

It is calculated as the ratio of true positives to the sum of true positives and false negatives, making it essential in scenarios where missing positive instances is more critical than incorrectly classifying negative instances.

F score

The F score provides a balanced measure of a model's performance by combining both precision and recall into a single metric, allowing for a comprehensive evaluation of the model's effectiveness.

It is calculated as the mean of precision and recall, where a higher F score indicates better overall performance.

Neural networks and deep learning

Neural networks and deep learning stand at the forefront of innovation, revolutionizing how machines perceive, learn and generate insights from data. Let’s understand how these powerful paradigms mimic the workings of the human brain, enabling computers to autonomously learn complex patterns and make decisions:

Convolutional neural network (CNN)

A CNN is a deep learning model specifically designed for processing structured grid data, such as images or audio.

CNNs are characterized by their ability to automatically learn hierarchical patterns and features directly from raw input data.

Generative adversarial network (GAN)

A generative adversarial network (GAN) is a type of deep learning model that consists of two neural networks: a generator and a discriminator, which are trained simultaneously through adversarial learning.

The generator network learns to generate synthetic data samples that are similar to the training data, while the discriminator network learns to distinguish between real and fake samples.
