Perceptron

A basic computational model that combines weighted inputs to make a threshold-based decision. It is a foundational neural network concept with limits on the patterns a single perceptron can represent.

PESTEL Analysis

A framework for examining political, economic, social, technological, environmental and legal factors affecting an organisation. It supports structured discussion, but conclusions require current evidence and relevant context.

Platform Strategy

A business approach that creates value through a platform connecting users, services or complementary providers. Assess participation, incentives and governance rather than assuming technology alone will create network effects.

Pose Estimation

Computer vision methods that estimate the position of body or object landmarks. Evaluate accuracy, operating conditions and privacy implications before applying the output to monitoring or decision-making.

Precision

For a classification task, the proportion of predicted positive cases that are actually positive. It helps assess false-positive errors and should be considered alongside recall and the consequences of mistakes.

Product/Market Fit

Evidence that a product meets a meaningful need in a defined market. Assess actual use, customer outcomes and willingness to continue purchasing rather than relying on interest or positive feedback alone.

Random Forest

An ensemble approach combining multiple decision trees for prediction. Evaluate performance, operating cost and interpretation needs on representative data before selecting it for a business application.

Recall

For a classification task, the proportion of actual positive cases that the model identifies. It helps assess missed cases and should be considered alongside precision and the cost of false negatives.
