Data analytics and AI
This glossary contains definitions related to customer data analytics, predictive analytics, data visualization and operational business intelligence. Some definitions explain the meaning of words used to Hadoop and other software tools used in big data analytics. Other definitions are related to the strategies that business intelligence professionals, data scientists, statisticians and data analysts use to make data-driven decisions.
Algorithms
Terms related to procedures or formulas for solving a problem by conducting a sequence of specified actions. In computing, algorithms in the form of mathematical instructions play an important part in search, artificial intelligence (AI) and machine learning.
-
What is a perceptron?
A perceptron is a simple model of a biological neuron used in an artificial neural network.
-
What is reinforcement learning?
Reinforcement learning (RL) is a machine learning training method that trains software to make certain desired actions.
-
gradient descent
Gradient descent is an optimization algorithm that refines a machine learning (ML) model's parameters to create a more accurate model.
Artificial intelligence
Terms related to artificial intelligence (AI), including definitions about machine learning and words and phrases about training data, algorithms, natural language processing, neural networks and automation.

-
What is data labeling?
Data labeling is the process of identifying and tagging data samples commonly used in the context of training machine learning (ML) models.
-
What is Bayes' theorem? How is it used in machine learning?
Bayes' theorem is a mathematical formula used in probability theory to calculate conditional probability, i.e., the revised likelihood of an outcome occurring given the knowledge of a related condition or previous outcome.
Data and data management
Terms related to data, including definitions about data warehousing and words and phrases about data management.
-
What is electronic data processing (EDP)?
Electronic data processing (EDP) refers to the gathering of data using electronic devices, such as computers, servers and internet of things (IoT) technologies.
-
What is data lifecycle?
A data lifecycle is the sequence of stages that a unit of data goes through from its initial generation or capture to its archiving or deletion at the end of its useful life.
-
What is bit rot?
Bit rot is the slow deterioration in the performance and integrity of data stored on storage media.
Database management
Terms related to databases, including definitions about relational databases and words and phrases about database management.
-
ISAM (Indexed Sequential Access Method)
ISAM (Indexed Sequential Access Method) is a file management system developed at IBM that enables records to be accessed either sequentially, in the order they were entered or randomly with an index.
-
data structure
A data structure is a specialized format for organizing, processing, retrieving and storing data.
