[en] In this work, we propose a new approach to detect anomalous graphs in a stream of di-
rected and labeled heterogeneous graphs. Our approach uses a new representation of graphs
by vectors. This representation is flexible and allows to update the graph vectors as soon as
a new edge arrives. In addition, it is applicable to any type of graph and optimizes memory
space. Moreover, it allows the detection of anomalies in real-time.
