Interactive code editor and syntax high-lighting.Syntactic sugar for simplified data access and alteration.Easy-to-use program development interface: Predefined imports for common data structures.Augment scoring logic by custom post-processing or model application procedures.Incorporate procedures from other processes or projects.Write scripts for easy-to-complex data preparation and transformation tasks where existing operators might not be sufficient.Various techniques for the estimation of model performance: Cross validation (with parallel execution of the folds).Display multiple results in history to help better evaluate model performance.Embed pre-processing steps into the validation.Performance estimation for cluster models based on distance calculations, density calculations, or item distributions.Find threshold operator to determine optimal cutoff point for binominal classes.Calculating significance tests to determine if and which models performed better.Performance criteria for numerical and nominal / categorical targets, including:.This unique approach is the only guarantee that no overfitting is introduced and no overestimation of prediction performances can occur RapidMiner Studio follows a stringent modular approach which prevents information used in pre-processing steps leaking from model training into the application of the model.Dimensionality reduction with Self- Organizing Maps (SOM).Choose the number of components to be retained.Calculates Eigenvalues and Eigenvectors from correlation and covariance matrices.Plots for principal components coefficients, Eigenvalues, and cumulative variance of Eigenvalues.– Removal of attributes unrelated to target based on arbitrary weighting schemes like information gain, Gini index, and others – Removal of attributes unrelated to target based on a chi-square or correlation-based selection criterion – Selection of attributes by user specification – 30+ weighting schemes measuring the influence of attributes & forming base or weight-based selections (filter approach) Miscellaneous functions: if then-else, square root, signum, random, modulus, sum, binomial, missing binomial, missing.Date functions: parse, parse with locale, arse custom, before, after, to string, to string with locale, to string with custom pattern, create current, difference, add, set, and get.
