Curse of dimensionality is associated with multivariate problems. When a phenomenon occurs in multi dimensions, its analysis and visualization becomes difficult. Its effects can be seen in various machine learning algorithms like nearest neighbors and visualization. To resolve these issues there are various dimension reduction methods most common methods are: PCA (Principal Component Analysis) and t-SNE (t distributed Stochastic Neighbor Embedding)
