Fig. 7From: Fog computing application of cyber-physical models of IoT devices with symbolic approximation algorithmsSchematic diagram of classification with the cosine similarity: a New data for query is first transformed into SFA words, b the SFA words of the new data is transformed into the BOSS histogram, c the trained model in the form of tf-idf algorithm is given, and d the classification is carried out through calculating the cosine similarity between the trained model and the queryBack to article page
