Abstract: Highlights•We propose the concept of almost aggregation functions to aggregate real positive numbers.•We propose a series of modifications to the gravitational clustering to solve the problem of anomaly detection.•We propose the use of different functions to generalize the aggregation of masses instead of the classical summation.
