The encoding methods discussed are foundational data science techniques and remain fully relevant for preparing data for machine learning models today. What is Categorical Feature Encoding? Categorical variables are usually represented as strings in limited numbers, while categorical feature encoding is the process of converting data […]

What is Bayesian Encoding? Bayesian Encoding is a type of encoding that takes into account intra-category variation and the target mean when encoding categorical variables.

Every industry uses a version of an audit trail when providing in-depth historical records. Audit trails are records that chronologically catalogue events or procedures. These trails provide proof-of-compliance and operational integrity. The audit trail essentially provides a “baseline” for analysis or an audit when initiating an investigation. The purpose or importance of an audit trail […]
