Annotation: The paper proposes the use of recurrent neural networks with the LSTM architecture for solving problems related to the detection of anomalous instances in data sets and compares the effectiveness of the proposed method with the traditional technique – the support vector machine for one class. During the study, an experiment was conducted and criteria for the effectiveness of implementations were formulated. The results obtained in this way made it possible to draw appropriate conclusions about the applicability of recurrent neural networks in the tasks of detecting anomalous instances and put forward proposals for the further development of this direction.
