Abstract: Systems, methods, and computer program for generating and using embedding vectors associated with real-time data are provided. A streaming platform receives streaming data associated with events occurring in a network environment. At least one neural network generates embedding vectors from the streaming data associated with the events. The analytical models analyze the embedding vectors and are updated with the result from the analysis. Embedding vectors are also associated with one or more indexes. The streaming platform may receive a query with an embedding vector associated with data from another event that is occurring in real-time in the network. Based on the embedding vector in the query, the streaming platform may use the one or more indexes to provide, in real-time, similar embedding vectors, which are indicative of similar events in the network environment.
