What are the main challenges in data representation?

Some key challenges include data quality, dimensionality, and the complexity of representing relationships.

Can you explain how data quality affects representation?

Data quality impacts accuracy and reliability; poor quality data can lead to misleading representations.

What is dimensionality in data representation?

Dimensionality refers to the number of features or variables in a dataset, which can complicate analysis.

How do we handle high-dimensional data?

Techniques like dimensionality reduction, such as PCA, help simplify high-dimensional data for better analysis.

Are there tools that can assist with data representation challenges?

Yes, tools like Tableau, Power BI, and various machine learning libraries can help visualize and manage data.
