Two-dimensional linear discriminant analysis - Experts@Minnesota Principal components analysis (PCA) is a linear dimensionality reduction (DR) method that is unsupervised in that it relies only on the data; projections are calculated in Euclidean or a similar linear space and do not use tuning parameters for optimizing the fit to the data. Such as a combination of PCA and LDA. Attrition of employees if not predicted correctly can lead to losing valuable people, resulting in reduced efficiency of the organisation, reduced morale among team members etc. Lecture 20- Linear Discriminant Analysis ( LDA) (with Solved Example) 43 0 obj << Finally, we will transform the training set with LDA and then use KNN. endobj Central Tendencies for Continuous Variables, Overview of Distribution for Continuous variables, Central Tendencies for Categorical Variables, Outliers Detection Using IQR, Z-score, LOF and DBSCAN, Tabular and Graphical methods for Bivariate Analysis, Performing Bivariate Analysis on Continuous-Continuous Variables, Tabular and Graphical methods for Continuous-Categorical Variables, Performing Bivariate Analysis on Continuous-Catagorical variables, Bivariate Analysis on Categorical Categorical Variables, A Comprehensive Guide to Data Exploration, Supervised Learning vs Unsupervised Learning, Evaluation Metrics for Machine Learning Everyone should know, Diagnosing Residual Plots in Linear Regression Models, Implementing Logistic Regression from Scratch.
