Data Science and Machine Learning (Theory and Projects) A to Z - Features in Data Science: Features Dimensions

The video discusses the concept of dimensionality in feature space, explaining that it refers to the total number of features in a dataset. It highlights the challenges of visualizing data with more than three dimensions and introduces the idea of axes and linear independence. The video also touches on practical examples of dimensionality and hints at the next video, which will address problems associated with high dimensionality.
