Look up any term in AI.

Self-supervised Learning (SSL)

Training a model on unlabeled data by hiding part of each input and making the model predict it — the paradigm behind next-token prediction and modern LLMs.

Activation Functions

Without a non-linearity, stacked layers collapse into one matrix. How activation functions fix that, and why ReLU, GELU and SwiGLU are the defaults.

AI Research

AI research is the systematic investigation into the development of algorithms, models, and systems that exhibit intelligent behavior.

AI in Finance

Machine learning that approves loans and blocks card fraud — where you ship the most accurate model you can defend, not the best one you can build.

Membership Inference

A privacy attack that decides whether a specific record was in a model's training set, exploiting that models are more confident on data they memorized.

Reasoning Model

A model trained to think at length before answering. How it differs from a chat model, what the effort dial does, and the tasks where it earns its price.
