Biotechnology
Neurotechnology
Technologies designed to understand, interface with, or manipulate the nervous system.
information-theory
noisy-channel-coding
A method for encoding data to protect against errors during transmission over noisy channels.
data-quality
noisy-labels
Labels in a dataset that are inaccurate or wrong, often leading to misguidance in model training.
machine learning
one-shot-learning
A machine learning approach that enables a model to learn information about object categories from a single training example.
Knowledge Representation
ontologies
Formal representations of a set of concepts within a domain and the relationships between those concepts.
Knowledge Representation
ontology
An ontology is a formal representation of a set of concepts within a domain.
Models and Deployment
Open Weights
Open weights are downloadable model parameters that teams can inspect, run, fine-tune, or redistribute only to the extent permitted by the model's license.
Security
OpenAI Daybreak
OpenAI Daybreak is a vetted access program that gives authorized cybersecurity defenders controlled use of frontier models—and, in Daybreak Red, purpose-trained cyber models such as GPT-5.6-Cyber.
machine learning
out-of-distribution-generalization
The ability of a model to perform well on unseen data that is different from the training set.
data-analysis
outlier
An observation point that is distant from other observations in the dataset.
Data Analysis
Outlier Detection
The identification of data points that deviate significantly from the majority of data.
Modeling
Overfitting
A modeling error that occurs when a model learns noise and details from the training data.
data-preprocessing
pipeline
A sequence of data processing steps for machine learning workflows.
evaluation
precision-recall-curve
A graphical representation of a model's trade-off between precision and recall.
Data Analysis
predictive-analytics
The use of statistical techniques to forecast future events based on historical data.
Data Science
Principal Component Analysis (PCA)
A dimensionality reduction technique used to simplify datasets while preserving variance.
data-analysis
principal-component-analysis
A dimensionality reduction technique that transforms data into a set of orthogonal components.
