Information Analysis

Work with information

Start here when your question concerns the information an AI system uses: where it comes from, how it is organized, whether it is reliable, and how to retrieve or analyze it. For a guided route, open Data & Knowledge Navigator.

Before choosing a model, describe the input, the desired output, and the evidence that would make the result useful. Check whether your examples represent the people, situations, and time periods the system will encounter. Data quality problems can remain hidden behind an impressive demonstration.

Algorithms

Understand and compare methods

Use AI Algorithms & Learning Methods Navigator when you need help choosing a representation or learning method. The directory below groups related approaches for browsing; some methods serve several tasks, so the groups are not mutually exclusive.

A useful comparison begins with the task and available data. Predicting a number, assigning a category, discovering groups, generating content, and choosing actions over time require different evidence. Start with a simple baseline, then compare more complex approaches using the same evaluation conditions.

Architecture of Modern Models

Many modern chat assistants, coding tools, and Agents use transformer-based language models. Other systems use different architectures or combine several approaches. These links introduce the main components and some alternatives.

Attention ... the mechanism that lets a model weigh which parts of its input matter for each element it produces
Transformer ... an architecture that combines attention with other components, including feed-forward layers, to process sequences
Generative Pre-trained Transformer (GPT) ... decoder-only transformers pre-trained on broad corpora, then adapted to specific tasks
Large Language Model (LLM) ... Multimodal ... models that accept and produce more than text
Retrieval-Augmented Generation (RAG) ... grounding generation in retrieved documents rather than relying on what the weights happen to encode
Mamba ... sequence models that scale differently than attention does
State Space Model (SSM) capture the system's internal behavior over time
Foundation Models (FM) trained on broad data that can be adapted to a wide range of tasks

Generative AI (Gen AI)

The ability to generate new content or solutions, such as writing or designing new products, using techniques such as Generative Adversarial Network (GAN) or neural style transfer.

Semi-Supervised

When labeled examples are scarce and unlabeled examples are plentiful, semi-supervised learning may help. It uses assumptions about the relationship between data structure and labels. Those assumptions need testing: unrelated or misleading unlabeled data can reduce performance. Reference: Learning Techniques

Reinforcement Learning (RL)

An agent learns to choose actions from interaction with an environment, aiming to improve expected cumulative reward. Rewards may be immediate or delayed. Neural networks can represent policies or value functions, but reward design, exploration, and evaluation remain important. Policy Gradient (PG) methods are a type of reinforcement learning techniques that rely upon optimizing parametrized policies with respect to the expected return (long-term cumulative reward) by gradient descent.

Neuro-Symbolic

The “connectionists” seek to construct artificial Neural Networks, inspired by biology, to learn about the world, while the “symbolists” seek to build intelligent machines by coding in logical rules and representations of the world. Neuro-symbolic approaches combine learned representations with explicit symbolic structures or reasoning. The integration varies by system; it does not automatically guarantee correct reasoning.

Techniques

Improve learning and test results

Use this directory to understand training, optimization, generalization, and evaluation. A change that improves a training score may still fail on new examples. Choose a metric that represents your actual task and keep evaluation examples separate from model development.

For a guided investigation, start with AI Experiments & Benchmarks Navigator. Record the model version, data, prompts, settings, and success criteria so another person can repeat the comparison.

Math for Intelligence ... Finding Paul Revere
Arxiv Sanity Preserver to accelerate research

Learning methods adjust a model or decision rule using examples, feedback, or interaction. Training changes learned parameters; inference applies the resulting model. Retrieval supplies relevant information at use time, while tools let a system perform operations outside the model. These mechanisms can be combined, but they address different needs.

AI runs on physical hardware. Memory capacity limits what can fit on a device, while memory bandwidth and computation affect response time and throughput. Larger inputs and more generated output generally require additional work. Model compression can reduce resource demands, but its effect on quality must be measured for the intended task. Hardware, workload, precision, and batching all matter when comparing performance.

Understanding these distinctions helps you choose an appropriate improvement. Better retrieval may help a system use relevant documents; additional training may change learned behavior; a faster processor may reduce waiting time. None of those changes alone proves that the answers are correct. Connect each proposed improvement to a measurable requirement and test it on examples that matter to your users.

Recent Developments

The 2026 AI Index describes strong progress on several capability benchmarks alongside uneven performance across tasks. Its examples contrast advanced mathematical performance with weaknesses in seemingly simpler visual tasks. The report also identifies gaps in responsible-AI evaluation. These findings make task-specific evaluation especially important: a strong aggregate score does not establish reliability in a particular workflow.

The 2026 AI Index Report | Stanford HAI Evidence across technical performance, responsible AI, science, education, and adoption. Read the relevant chapter and its measurement conditions before comparing results.

For practical experiments, compare the complete system rather than only its underlying model. Retrieval, tools, prompts, permissions, and stopping conditions can all affect an agent's results. Separate fixed workflows from systems that choose their own next actions, and increase autonomy only when evaluation supports the change.

Building effective agents | Anthropic Engineering guidance on workflows, agents, tool design, and starting with simple approaches. This is practitioner guidance, not proof that one architecture works best for every task.

When reviewing a new result, ask what was measured, which model and settings were used, whether the test resembles your task, and whether another team has reproduced it. Treat demonstrations as examples to investigate and benchmarks as evidence within their stated conditions.

Trust, Safety & Governance

Capability and trustworthiness are separate problems, and the second one does not solve itself. These pages cover the constraints that determine whether a working system is one you can actually deploy.

Development & Implementation

Turn an idea into a working system

Start with AI Tools & Infrastructure Navigator when you need to select, connect, or operate system components. Define one useful workflow before selecting a platform. Identify its inputs, expected outputs, users, and acceptable failure behavior.

A prototype tests an idea; an operational system also needs monitoring, access controls, maintenance, and a clear response when something fails. Compare quality, response time, cost, and integration effort using representative tasks. Keep a simple working baseline so you can tell whether additional complexity earns its place.
