## There are many TDA libraries available. How is giotto-tda different?¶

giotto-tda is oriented towards machine learning (for details, see the guiding principles). This philosophy is in contrast with other reference libraries, like GUDHI, which provide more low-level functionality at the expense of being less adapted to e.g. batch processing, or of being tightly integrated with scikit-learn.
