Rol	Obligatorio	Descripción
Data Scientist		Understands the curse of dimensionality concept and the need for dimensionality reduction. Applies PCA for feature reduction, interprets explained variance ratio. Visualizes high-dimensional data via t-SNE and PCA.

Rol	Obligatorio	Descripción
Data Scientist		Applies various dimensionality reduction methods: PCA, SVD, UMAP, autoencoders for feature extraction. Selects the optimal method based on task and data. Uses dimensionality reduction as a preprocessing step to improve model quality.

Rol	Obligatorio	Descripción
Data Scientist		Designs pipelines for very high-dimensional data (100K+ features). Applies non-linear dimensionality reduction, kernel PCA, variational autoencoders. Optimizes trade-off between compression ratio and information loss for production ML.

Rol	Obligatorio	Descripción
Data Scientist		Defines dimensionality reduction standards for the data science team. Establishes guidelines for method selection for different data types. Coordinates integration of dimensionality reduction into the feature engineering platform.

Rol	Obligatorio	Descripción
Data Scientist		Shapes high-dimensional data strategy at organizational level. Evaluates state-of-the-art methods (contrastive learning, self-supervised representations) for scaling feature engineering.
