# Applications¶

One of the beauties of Mapper is that it can be used on wide variety of data and problems. Here we highlight a few cases.

## Anomaly Detection¶

KeplerMapper can be used for anomaly detection. Anomaly detection is useful for fighting fraud and finding errors. Projecting with knn_distance_5 can surface outliers. There are also specialized outlier detection algorithms, like the Isolation Forest and GLOSH, that make good projections for anomaly detection.

## Natural Language Processing¶

Mapper can be used to explore bias in Word2Vec models.
