AI: A Complete Guide in Simple Terms

What is AI?

The term artificial intelligence (AI) refers to a field of computer science that designs machines advanced enough to perform tasks that in the past required human intelligence to achieve. AI scientists develop algorithms and systems that acquire, process, and analyze data, recognize patterns, and make decisions.

The main goal of AI is to replicate or simulate the cognitive abilities of humans, such as communication, learning, perception, problem-solving, and reasoning. It enfolds various subfields, including computer vision, expert systems, machine learning, natural language processing, and robotics.

Understanding AI Technology: What is AI Technology in Historical Context?

To understand AI, it is important to see how the field developed. The technology itself was directly inspired by the human brain and its function, and each series of advances was made possible by new understandings of how the human brain works as well as technological advances.

AI development began in the mid-20th century when researchers invented electronic computers. Researchers like Alan Turing and John von Neumann proposed the idea of machines that could simulate human thought processes, and Turing proposed the “Turing test” as a means for testing a machine’s ability to exhibit intelligent, human-like behavior.

The Dartmouth Conference in 1956 is often seen as the formal starting point for the birth of AI as a formal research field. There, researchers in the field coined the term “artificial intelligence” and set the goal of creating machines that could “simulate every aspect of human intelligence.”

In the 1950s-1960s, researchers focused on developing early AI programs that could solve problems symbolically using logical reasoning. By the 1970s, AI research moved towards knowledge-based systems, which represented knowledge in the form of rules and used inference engines to reason and solve problems.

Then, in the 1980s and 1990s machine learning and neural networks brought new approaches to AI. Machine learning algorithms, such as decision trees and neural networks, allowed systems to learn patterns and make predictions based on data. This period also saw the rise of expert systems and the development of natural language processing (NLP) techniques.

By the turn of the century and through the 2010s, AI and big data as well as increased computational power led to more advanced deep learning. Deep neural networks with multiple layers became capable of automatically learning hierarchical representations, enabling breakthroughs in computer vision, speech recognition, and much more sophisticated NLP systems.

More recently, breakthroughs in reinforcement learning and generative AI models are being applied in various domains, including self-driving cars, virtual assistants, healthcare diagnostics, finance, and more. This is a tremendous piece of why AI is important: it is already here, all around us.

How Does AI Work? AI Technology Explained

Deep learning in AI is a critical part of how AI works, and this process is inspired by the structure and function of the human brain. AI technology processes and analyzes data using algorithms and computational models. These tools allow the system to recognize patterns, and make decisions or predictions.

Deep learning AI technology involves the use of artificial neural networks (ANNs) with multiple networked layers of artificial neurons or nodes called “units.” Each unit receives inputs, assigns them weight, performs calculations, and passes the results to the next layer. Deep learning models extract features or hierarchical representations from the data automatically, enabling them to capture complex patterns and relationships.

Model architecture design involves defining the number and type of layers, the number of units in each layer, and the connections between them. Common architectures include convolutional neural networks (CNNs) which are mainly used for image data, feedforward neural networks which are mainly used for supervised learning, and recurrent neural networks (RNNs) which are mainly used for sequential data.

During the training phase, the deep learning model learns over time how to adapt the biases and weights of the labeled data’s neural network. Typically the model deploys optimization algorithms, which iteratively update the model’s parameters, to minimize the difference between the actual and predicted outputs.

After the deep learning model is trained, it can make predictions on new, unseen data. The trained model takes input data, performs forward propagation, and generates predictions or class probabilities based on the learned patterns.

AI Development and AI Models

An AI model is a computational representation of an AI system. These models are designed to learn patterns, make predictions, or perform specific tasks based on the input data they receive. Users can create x using various techniques and algorithms, depending on the problems they are designed to solve.

Here are a few common types of AI models:

Statistical models. Statistical models analyze data and make predictions using mathematical models and statistical techniques. They are often based on probabilistic methods and can handle structured or tabular data. Examples include linear regression, logistic regression, decision trees, and support vector machines.

Machine learning models (MLMs). MLMs automatically learn patterns and relationships from data and can adapt and improve their performance with experience. Popular machine learning algorithms include k-nearest neighbors, naive Bayes, random forests, and gradient boosting algorithms like XGBoost and LightGBM.

An AI pipeline or AI data pipeline refers to the sequence of steps or stages involved in developing and deploying AI systems. An AI pipeline encompasses the entire lifecycle of an AI project, from data collection and preprocessing to model training, evaluation, and deployment. It provides a systematic framework for managing and organizing the various tasks and components involved in AI development.

Here are the typical stages or components found in an AI pipeline:

Data collection. The pipeline begins with gathering relevant data to train and evaluate the AI model. It can come from various sources, such as databases, APIs, sensors, or human-generated annotations.

Data preprocessing. Data often needs to be preprocessed, cleaned, and normalized to prepare it for training before it is input into the AI model.

Feature engineering. Feature engineering involves extracting, selecting, or creating relevant data features to help the AI model learn patterns and make more accurate predictions. This step may involve domain expertise, statistical analysis, or automated feature selection techniques.

Model development. The AI model architecture and algorithm are selected in this stage based on the specific problem. Development can involve choosing from statistical models, machine learning algorithms, or deep learning architectures. The model is then trained using the prepared data.

Model evaluation. The performance and generalization capabilities of the trained model are evaluated according to various metrics depending on the task, such as accuracy, precision, recall, F1 score, or area under the curve (AUC). Cross-validation or hold-out validation sets are often used to estimate the model’s performance.

Model optimization. If the model does not meet the desired performance criteria, it can be optimized with hyperparameter tuning, model architecture adjustment, or regularization techniques to improve its performance.

Deployment and integration. Once it has reached satisfactory capabilities, including considerations of scalability, reliability, security, and monitoring, the model can be deployed into the production environment. Deployment involves integrating the model into a larger system or application, often using APIs or microservices.

Monitoring and maintenance. After deployment, the AI system must be monitored to ensure continued performance and reliability. This includes monitoring data drift, model performance degradation, and handling updates or retraining as new data becomes available.

AI pipelines provide a structured approach to AI development, allowing teams to collaborate, track progress, and ensure the quality and efficiency of the AI systems they create. They help streamline the workflow and facilitate the development of robust and reliable AI solutions.

AI Pipeline Architecture

AI pipeline architecture refers to the design and structure of the pipeline that supports the development, deployment, and management of AI systems. The specific architecture of an AI pipeline can vary depending on the organization, project requirements, and technologies used. However, there are common components, principles, and considerations that are typically involved in constructing an AI pipeline architecture:

Data storage and management. AI pipelines demand a robust, scalable AI storage system to handle the massive volumes of data that AI projects need. This may involve databases, data lakes, data oceans, or other distributed AI storage systems. Data management techniques, such as data versioning, metadata management, and data governance, ensure data quality and traceability.

Data preprocessing and transformation. This component of the pipeline handles the preprocessing and transformation of raw data into a suitable format for model training. It includes tasks such as data cleaning, feature extraction, normalization, and dimensionality reduction. Tools and frameworks for data preprocessing are often used in this stage.

Model development and training. Building and training AI models involves selecting appropriate algorithms, architectures, and frameworks based on the problem and available resources. GPUs or specialized hardware accelerators may be utilized to speed up the training process.

Model evaluation and validation. Performance assessment of trained models using appropriate evaluation metrics and techniques involves using validation sets or cross-validation to estimate performance and compare different models or hyperparameters. Visualization tools and statistical analysis techniques may help users interpret the evaluation results.

Model deployment and serving. The trained and evaluated model needs to be deployed into a production environment where it can serve predictions or perform tasks in real-time. This involves setting up APIs, microservices, or serverless architectures to expose the model’s functionality. Containerization technologies like Docker and orchestration tools like Kubernetes are often used to manage the deployment process.

Monitoring and management. This involves monitoring performance, detecting anomalies or drift in data distributions, and handling retraining or updates as necessary. Logging, error tracking, and performance monitoring tools help in effective management of deployed models.

Security measures such as access controls, encryption, and secure communication protocols are crucial to protect sensitive data and ensure compliance with privacy regulations.

The 4 Types of AI

There are four basic, different types of AI models that also represent incremental steps in AI technology development.

Reactive AI. Reactive AI systems are the most basic type, lacking memory and the ability to use past experiences for future decisions. Reactive machines can only respond to current inputs and do not possess any form of learning or autonomy. Examples of reactive AI include computers that play chess by analyzing the current board state to make the best move, or voice assistants that respond to user commands without any contextual understanding.

Limited memory AI. These systems make informed decisions based on a limited set of past experiences that they retain. These systems enhance their functionality by incorporating historical data and context. Self-driving cars often use limited memory AI to make driving decisions, considering recent observations such as the position of nearby vehicles, traffic signals, and road conditions.

Theory of mind. AI systems with a theory of mind possess an understanding of human emotions, beliefs, intentions, and thought processes. These systems can attribute mental states to others and predict their behavior based on those attributions. Theory of mind AI is still largely theoretical, but as an area of research it aims to enable machines to interact with humans more effectively by understanding their mental states and social cues.

Self-aware AI. AI systems that are truly self-aware with actual consciousness or the ability to recognize themselves and their own thoughts and emotions are as yet a highly speculative, unrealized concept, but they remain of philosophical and ethical interest and discussion.

Strong AI vs Weak AI

“Artificial intelligence” describes both the overall field and specific technologies or systems that exhibit intelligent behavior. In addition to the 4 types of AI, there are also three ways to think of AI: weak AI; strong AI; and super AI or artificial general intelligence.

What is weak AI? Weak or narrow AI systems are designed for particular tasks and specific problems within a limited domain. Some weak AI examples include voice assistants like Alexa or Siri, image recognition systems, recommendation algorithms, and chatbots.

What is strong AI? Strong or general AI systems possess the ability to understand, learn, and apply knowledge across various domains, essentially displaying human-level intelligence. True strong AI examples remain largely hypothetical for now.

AI vs ML Explained

This is a broad topic with many intersecting subcategories that are often confused conversationally, yet there is an important difference between AI and ML.

What are the principal differences between AI vs machine learning (ML)?

Machine learning (ML), a subset of artificial intelligence, is the ability of computer systems to learn to make decisions and predictions from observations and data. Machine learning is used in many applications, including life sciences, financial services, and speech recognition.

ML involves the development of models and algorithms that allow for this learning. These models are trained on data, and by learning from this data, the machine learning model can generalize its understanding and make predictions or decisions on new, unseen data.

Machine learning algorithms can be categorized as supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, based on its characteristics, goals, and approaches to learning from data.

Supervised learning is a type of ML model that learns from labeled data. In supervised learning, the training data includes input samples (features) and their corresponding desired output labels. The model learns to map inputs to outputs based on the labeled examples and can make predictions on unseen data.

Unsupervised learning is a type of ML model that learns from unlabeled data. In unsupervised learning, the training data does not have explicit output labels. The model learns to find patterns, structures, or relationships in the data without specific guidance. Clustering and dimensionality reduction are common tasks in unsupervised learning.

Semi-supervised learning is a hybrid of the previous machine learning methods. This approach provides the learning algorithm with unstructured (unsupervised) data while it includes a smaller portion of labeled or structured (supervised) training data. This often supports more rapid and effective learning on the part of the algorithm.

Often used for agents within a simulated environment (for example, an artificial agent in a video game), the reinforcement learning approach leverages the concept of cumulative award and Markov decision chains to teach optimal actions in dynamic settings. It is often used in online games and non-gaming environments like swarm intelligence modeling, simulations, and genetic-modeling algorithms.

So, what about the deep learning from the discussion at the beginning of this guide? There are various differences and connections between AI vs machine learning vs deep learning.

AI as a broader field is focused on all intelligent systems that can simulate human intelligence, understand, learn, and perform tasks. It encompasses various subfields, including computer vision, machine learning, and others.

As of 2023, the United States does not have comprehensive federal AI regulations, although in 2020 guidance was provided for the heads of federal agencies and departments. However, there have been discussions, initiatives, and proposals related to AI governance and regulation at both the federal and state levels.

See, for example:

  • The National Telecommunications and Information Administration, a Commerce Department agency that advises the White House on telecommunications and information policy, has begun to seek public comments on potential accountability measures for AI systems.
  • The OSTP has also proposed an AI Bill of Rights, found here.
  • Previously in 2019, the White House issued the Executive Order on Maintaining American Leadership in Artificial Intelligence, which directed federal agencies to prioritize AI investments, promote AI research and development, and enhance AI education and workforce development.
  • The National Institute of Standards and Technology (NIST) has been actively involved in developing standards and guidelines for AI. They have published documents such as the NIST Special Publication 800-209 on the trustworthiness of AI systems and the NIST AI Risk Management Framework to address the challenges of managing AI risks.
  • Additionally, the Federal Trade Commission (FTC) has been focused on addressing consumer protection and privacy concerns related to AI. They have issued guidelines and reports emphasizing the need for transparency, fairness, and accountability in AI systems, especially regarding bias, discrimination, and data protection.
  • California passed the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), which include provisions related to AI regulation and data privacy.

What is Generative AI?

Generative AI is a branch of AI that focuses on the creation and generation of new content, such as images, text, music, or other forms of creative output. It involves training AI models to learn from existing data and then generate new, creative content that is similar.

Generative AI models are designed to understand patterns and structures within the training data and use that knowledge to produce novel, coherent outputs. These models can generate content that closely resembles the examples they were trained on or create entirely new and original content based on the learned patterns.

There are several kinds of generative AI models:

Generative Adversarial Networks (GANs). GANs consist of two neural networks, a generator and a discriminator, which are trained in tandem. The generator network learns to produce realistic outputs, while the discriminator network learns to distinguish between real and generated examples. Through an adversarial training process, GANs can generate realistic images, videos, and other content.

Variational Autoencoders (VAEs). VAEs are probabilistic models that learn a compressed representation (latent space) of input data. They can generate new data by sampling from the learned latent space and then reconstructing it back into the original data space. VAEs are commonly used for generating images, text, and other structured data.

Recurrent Neural Networks (RNNs). RNNs are networks that are suited well for sequential data, such as text or music. They can learn the patterns and dependencies within the training data and generate new sequences based on that knowledge. RNNs are often used in natural language generation and music composition.

Generative AI Examples 

Generative AI use cases exist now in various fields:

  • Art and design. Generative AI can create new visual art, logos and other designs, and more.
  • AI in entertainment and music. This kind of AI has already created songs in the style of some artists.
  • Marketing, advertising, and content creation. This type of tool can create fictional characters, write stories, and help in creating personalized marketing campaigns and advertisements, targeting specific demographics.
  • Gaming. Generative AI can create new levels, characters, and scenarios in games, making them more engaging and interactive.
  • Medicine and research. This technology can even assist in drug discovery by generating novel chemical structures.
  • Fashion and retail. Generative AI can create new clothing designs and predict fashion trends.
  • Technology. These tools can help write documentation and code projects.
  • Customer service. Generative AI can handle customer and internal queries when trained on knowledge bases.

However, concerns surrounding generative AI include ethical considerations, such as the potential for generating misleading or harmful content, deepfakes, or the unintentional biases present in the training data being reflected in the generated output.

The Future of AI.  What’s Next?

Given that there has been such rapid change in the field recently, what is the future of AI right now? In general, AI is becoming more and more like the human brain, and less constrained in traditional ways.

The most obvious changes we are likely to see in the coming years will affect us as a few broader trends:

  • Pace of culture and life ticks up. As massive organizations make data-driven decisions ever more rapidly, their cultural organizations will be more nimble. Those kinds of larger shifts toward a faster pace in life generally can push the rest of us to live a little more quickly, too.
  • Less privacy, enhanced security. We’ve already seen a trend toward reduced privacy, especially online. The cost of enhanced convenience and speed is, at times, less privacy—at least from your friendly U/X bot. But enhanced security, especially for data, will be paramount for user trust to be sustained in these platforms.
  • The law of AI will develop. 2023 has seen federal hearings on what the law surrounding AI should be, and the law in this area is poised to develop rapidly alongside internet law generally.
  • Human/AI interface. This is coming already, as researchers experiment with restoring the ability to move or speak for people with severe disabilities.
  • Continued demands for sustainability. The need to conserve energy and find sustainable solutions for data management and storage will only grow more urgent in the future, and rapidly as technology evolves.

What is Storage for AI?

One of the key challenges to achieving sustainable AI is storage. IT infrastructure is in a state of continuous change, but rethinking storage for AI/ML workloads can help ease this process.

Data enters the ML pipeline at each stage; which kind of AI storage system is best suited to handle it?

  • Ingestion. During the data- and capacity-intensive ingest stage, the data is collected and placed into data lakes, where it needs to be classified and sometimes needs to be cleaned.
  • Preparation. AI and ML demand extremely high-throughput operations, so the data preparation phase requires write speed to support many sequential writes.
  • Training. The resource-intensive training of the AI/ML pipeline is a latency-sensitive process rather than a data-intensive process, with high influence on the ultimate time to result for the project.
  • Inference. In this stage you need extremely low latency. Maybe you have smaller IO and mixed workloads, but extremely low latency is what’s important here.
  • Staging and archive. AI/ML demands a large amount of data to test and run its models—a multi-petabyte scale of active archive might be required at this stage.

The challenge is the type of AI storage system that is best-suited to the data at hand.

There are six aspects of AI/ML infrastructures consider:


AI/ML practitioners generally need the ability to deliver storage anywhere. In a modern environment, data and storage can be anywhere—yet many storage solutions are still designed with a single data center in mind. Data might still be deployed within a data center, but some data storage also will be deployed at the edge, in the cloud, or elsewhere.


AI/ML workloads must support modern libraries so they are not stuck in a silo. An AI/ML project should be deployed alongside and sub-provisioned by developers or business owners and must be compatible with provisioning tools. It must learn all of the APIs and handle the workload—in self-service mode, as well. Finally, the architecture must support container platforms, mostly Kubernetes-oriented applications.


Scale is important, especially for unstructured data. However, architecture also needs to change, because while scaling up is very important, so is scaling down.

Many projects start small and grow as needed, so there is no need to invest in a multi-petabyte solution or expand beyond a small footprint—and some types of storage don’t scale in the right ways for AI. Network Attached Storage (NAS), for example, is a vertical platform that cannot scale out to the sizes and in the distributed, horizontal ways required for AI/ML workloads.


AI/ML workloads demand the highest possible performance. Workloads with high-throughput, large IO, and random reads and writes must coexist harmoniously and with low latency. This requires new protocols, new flash media, new software, and GPUs for the training phase of AI/ML. The biggest weak spot in this chain is feeding enough data into the system; keeping storage full of ready-to-use data is the only way to achieve this.

Software-defined models

In terms of portability, an AI model needs to be deployed anywhere using software-defined architecture that is appliance independent yet supports modern hardware innovations. For example, software-defined-storage vendors were the first supporters of NVMe technology, and just as their software independence made them good partners then, they remain ideal for people who need to deploy AI/ML workloads for data management anywhere across the edge, core, and cloud.

Cost optimization

To right-size AI storage investment for AI/ML, it’s critical to plan beyond training and inference, the most demanding phases of the project, and through the entire data lifecycle of storage. Deploying all data on a single platform becomes prohibitively large and expensive, but planning with all phases of the work in mind, including active archiving and deep archiving, allows practitioners to maximize their TCO for the entire AI/ML process for less money.
