Foundations

What is Artificial Intelligence?

Definition

Machines that perform tasks associated with intelligence

Artificial Intelligence (AI) is a field of computer science focused on building systems that can perform tasks normally associated with human intelligence — such as recognizing speech, understanding language, identifying images, making predictions, and solving problems. Rather than following only fixed, hand-written rules, modern AI systems learn patterns from data.

Types

Narrow vs. general AI

Almost all AI in use today is narrow AI: systems specialized for specific tasks like translation, recommendation, or image classification. Artificial general intelligence (AGI) — a system with broad, human-level capability across many domains — remains a research goal, not a current reality.

How it learns

Data, models, and training

Most modern AI is built with machine learning: an algorithm is shown many examples and gradually adjusts internal parameters to reduce its errors. The result is a model — a mathematical function that maps inputs (text, pixels, audio) to useful outputs (answers, labels, predictions).

Everyday AI

Where you already meet AI

Spam filters, voice assistants, photo search, autocomplete, translation, navigation, and content recommendations all rely on machine learning. AI is less a single product and more a layer of capability woven through modern software.

Learning from data

Machine Learning & Neural Networks

Supervised

Supervised learning

The model learns from labeled examples — inputs paired with correct answers. It is the workhorse behind classification (is this email spam?) and regression (what will this house sell for?).

Unsupervised

Unsupervised learning

The model finds structure in unlabeled data — clustering similar items, compressing information, or detecting anomalies without being told what to look for.

Reinforcement

Reinforcement learning

An agent learns by acting in an environment and receiving rewards or penalties — the approach behind game-playing systems and many robotics controllers.

Neural networks

Layers of simple units

A neural network is built from layers of simple mathematical units (“neurons”). Each connection has a weight; training adjusts millions or billions of these weights so the network maps inputs to the right outputs.

Deep learning

Why “deep” matters

“Deep” learning uses many stacked layers, letting networks learn hierarchies of features — edges become shapes, shapes become objects; characters become words, words become meaning.

Training

Gradient descent

Training works by measuring the model’s error (the “loss”) and nudging every weight in the direction that reduces it — repeated across enormous datasets until the model performs well.

Language at scale

What is an LLM?

Large Language Model

Predicting the next token

A Large Language Model (LLM) is a deep neural network — typically based on the transformer architecture — trained on vast amounts of text. At its core, it learns to predict the next token (a word or word-fragment) given everything that came before. From this simple objective emerge abilities like answering questions, summarizing, translating, and writing code.

Transformers

Attention is the key idea

Transformers use a mechanism called self-attention, which lets every token in a sequence weigh its relationship to every other token. This is what allows LLMs to track context across long passages instead of only looking at nearby words.

Lifecycle

Pre-training, fine-tuning, alignment

  • Pre-training: learn general language patterns from large text corpora.
  • Fine-tuning: specialize on curated data for particular tasks or styles.
  • Alignment (e.g. RLHF): use human feedback to make outputs more helpful and safer.
Limitations

Know the failure modes

LLMs can hallucinate — produce fluent but incorrect statements. They have knowledge cutoffs, finite context windows, and can reflect biases present in training data. Treat outputs as drafts to verify, not facts to trust blindly.

Human language

What is NLP?

Field

Natural Language Processing

NLP is the branch of AI concerned with enabling computers to understand, interpret, and generate human language — the bridge between how people communicate and how machines compute.

Classic tasks

What NLP systems do

  • Sentiment analysis & text classification
  • Named-entity recognition
  • Machine translation
  • Summarization & question answering
  • Speech-to-text and text-to-speech
Evolution

Rules → statistics → neural

NLP evolved from hand-written grammar rules, to statistical methods, to word embeddings, and finally to transformer-based models — each step handling more ambiguity and context than the last.

Silicon for intelligence

NPU vs GPU vs CPU

CPU

Central Processing Unit

The general-purpose brain of a computer. Great at sequential logic and running operating systems and applications, but with relatively few cores, it is not ideal for the massive parallel math AI requires.

GPU

Graphics Processing Unit

Originally built for rendering graphics, GPUs contain thousands of small cores that excel at parallel matrix operations — exactly the math neural networks need. GPUs power most large-scale AI training today.

NPU

Neural Processing Unit

A chip designed specifically for neural-network workloads. NPUs accelerate operations like matrix multiplication at low power, making them ideal for on-device AI in phones and laptops — enabling features that run locally without the cloud.

Also notable

TPUs and AI accelerators

Tensor Processing Units (TPUs) and other custom accelerators are data-center chips purpose-built for training and serving large models. The broader category is often called “AI accelerators.”

Why it matters

Edge vs. cloud inference

Running models in the cloud offers scale; running them on-device (the “edge”) offers privacy, lower latency, and offline capability. NPUs are central to the shift toward hybrid AI that uses both.

Teaching machines to interpret images and video — object detection, face recognition, medical-image analysis, and the perception systems in autonomous vehicles.

Generative AI

Creating new content

Models that generate text, images, audio, video, or code. Includes LLMs and diffusion models, which iteratively refine noise into images guided by a text prompt.

Speech

Speech & audio AI

Automatic speech recognition (ASR) converts audio to text; text-to-speech (TTS) synthesizes natural-sounding voices; other models separate, enhance, or classify sound.

A technique that lets a language model look up relevant documents at answer time, grounding its responses in retrieved sources to reduce hallucination and keep information current.

Agents

AI agents

Systems that pair a model with tools, memory, and the ability to plan multi-step actions — moving from “answer a question” toward “complete a task.”

Building responsibly

AI Ethics & Safety

Bias & fairness

Models reflect their data

Training data can encode historical and societal biases, which models may reproduce or amplify. Responsible development includes auditing datasets, measuring disparate outcomes, and mitigating harm.

Transparency

Explainability matters

People affected by AI decisions deserve to know when AI is involved and, where possible, why a system produced a given output — especially in high-stakes domains like hiring, lending, and healthcare.

Privacy

Data stewardship

AI systems often process personal information. Principles like data minimization, consent, security, and purpose limitation — reflected in regulations such as the GDPR — apply directly to AI pipelines.

Regulation

An evolving legal landscape

Frameworks such as the EU AI Act introduce risk-based rules for AI systems, while standards bodies and national strategies worldwide are shaping requirements for safety, accountability, and human oversight.

Common questions

AI FAQ

Is AI the same as machine learning?

Not exactly. AI is the broad goal of building intelligent systems; machine learning is the dominant technique for achieving it, where systems learn from data rather than being explicitly programmed. Deep learning is, in turn, a subset of machine learning.

Do LLMs actually “understand” language?

This is debated. LLMs model statistical patterns in language extremely well and can perform tasks that look like understanding, but whether this constitutes understanding in a human sense is an open philosophical and scientific question.

Why do AI models make things up?

Language models generate the most plausible continuation of text based on patterns they learned — plausibility is not the same as truth. Techniques like retrieval-augmented generation and citation grounding help, but verification by humans remains important.

What is the difference between training and inference?

Training is the expensive process of adjusting a model’s parameters using large datasets and significant compute. Inference is using the finished model to produce outputs — far cheaper per request, and increasingly possible on local devices with NPUs.

Will AI replace human jobs?

AI changes tasks more than it eliminates whole jobs outright — automating some activities while creating demand for new skills. The impact varies widely by industry and role, and is an active area of economic research and policy debate.

How can I start learning AI?

Start with the fundamentals: Python, linear algebra basics, and an introductory machine-learning course. Then build small projects, experiment with open models, and read papers or explainers — like the ones in our blog.
