A method for representing text by the frequency of each word, ignoring grammar and word order.

Bandwidth in AI

The capacity of a system to process data; in marketing this affects how quickly models can handle large campaign datasets.

Bayesian Inference

A statistical method that updates the probability of a hypothesis as more evidence becomes available.

Bayesian Network

A probabilistic graphical model representing conditional dependencies among variables.

Bayesian Optimization

An optimization technique that uses Bayesian inference to find the optimal parameters for a function or model.

Behavioral Analytics

Analysis of customer behaviour data to uncover patterns that inform marketing strategies and personalization.

Benchmarking in AI

Measuring model performance against standard data sets or industry benchmarks to ensure quality and fairness.

Bias in AI

Systematic errors that produce unfair outcomes due to skewed data or model design; marketers must mitigate bias to ensure equitable campaigns.

Bias‑Variance Tradeoff

The balance between model complexity (variance) and generalization (bias) that determines predictive accuracy.

Big Data

Extremely large data sets that require specialized tools for storage, analysis and processing.

Binary Classification

A predictive task where the output is one of two classes, such as churn vs. not churn.

Bit Depth

The number of bits used to store each pixel, affecting the range of colours or shades in images.

Black Box AI
