1) Record-based Data ModelsWhen the database is organized in some fixed format of records of several than the model is called record-based data model. A fixed number of fields, or attributes in each record type and each field is usually of a fixed length. The three most popular record-...
Bias is a statistical distortion that can occur at any stage in the data analytics lifecycle, including the measurement, aggregation, processing or analysis of data. Often, bias goes unnoticed until you've made some decision based on your data, such as building a predictive mo...
Data visualization also plays a crucial role in evaluatingmachine learningmodels. By plotting the actual and predicted values of a model, data scientists can assess its performance and identify areas for improvement. Popular model evaluation visualizations include confusion matrices,ROC curves, and residua...
