According to examples, an apparatus may include a processor and a non-transitory computer readable medium on which is stored machine readable instructions that may cause the processor to identify Internet protocol (IP) addresses and connection attributes associated with the IP addresses. The instructions may also cause the processor to train a machine learning model using the IP addresses as inputs to the machine learning model and connection contexts as outputs of the machine learning model. The machine learning model may learn a first weight matrix corresponding to the IP addresses and a second weight matrix corresponding to the connection contexts. In addition, the connection contexts may be concatenations of the connection attributes associated with a corresponding IP address.

Train a machine learning model using IP addresses and connection contexts

In some examples, a system is to, given an anomaly score threshold over which at least one anomalous point is to be observed in a test set of points with a specified probability, determine, using raw anomaly scores for a training set of points, a first mapping between raw anomaly scores in a first range and first transformed anomaly scores using a first transformation technique. The system is to determine, using the raw anomaly scores for the training set of points, a second mapping between raw anomaly scores in a second range greater than the first range and second transformed anomaly scores using a second transformation technique different from the first transformation technique. The system is to use the first mapping and the second mapping to detect an anomaly in a computing environment based on the test set of points.

Mapping between raw anomaly scores and transformed anomaly scores

In some examples, a system determines a dependency among a plurality of anomaly detectors, the determining comprising clustering anomaly detectors of the plurality of anomaly detectors into clusters of anomaly detectors. The system aggregates anomaly scores produced by anomaly detectors in a first cluster of anomaly detectors, to generate a first aggregate anomaly score, and detects an anomaly using the first aggregate anomaly score.
