    Applying Recurrent Neural Networks for Anomaly Detection in Electrocardiogram Sensor Data by Ana Minic, Luka Jovanovic, Nebojsa Bacanin, Catalin Stoean, Miodrag Zivkovic, Petar Spalevic, Aleksandar Petrovic, Milos Dobrojevic, Ruxandra Stoean

    Published 2023-12-01
    “…This work explores the potential of recurrent neural networks for anomaly detection in ECG readings. Furthermore, to attain the best possible performance for these networks, training parameters, and network architectures are optimized using a modified version of the well-established particle swarm optimization algorithm. …”

    Anomaly Detection on Natural Language Processing to Improve Predictions on Tourist Preferences by Jorge Meira, João Carneiro, Verónica Bolón-Canedo, Amparo Alonso-Betanzos, Paulo Novais, Goreti Marreiros

    Published 2022-03-01
    “…We also used a distinctive approach in this field through unsupervised techniques for anomaly detection problems. The goal was to improve the supervised model in identifying only those tourists who truly like or dislike a particular point of interest, in which the main objective is not to identify everyone, but fundamentally not to fail those who are identified in those conditions. …”

    TEC Anomalies Detection for Qinghai and Yunnan Earthquakes on 21 May 2021 by Yingbo Yue, Hannu Koivula, Mirjam Bilker-Koivula, Yuwei Chen, Fuchun Chen, Guilin Chen

    Published 2022-08-01
    “…The long short-term memory model is a kind of method to predict time series and has been used for the prediction of total electron content, and the relative power spectrum method is one of the pre-seismic infrared anomaly detection algorithms in the frequency domain. In this paper, a new method combining these two algorithms is used to extract abnormal signals; thus scientists can more easily detect anomalies of total electron content similar to those before the Qinghai and Yunnan earthquakes happened on 21 May 2021. …”

    Progressive Temporal-Spatial-Semantic Analysis of Driving Anomaly Detection and Recounting by Rixing Zhu, Jianwu Fang, Hongke Xu, Jianru Xue

    Published 2019-11-01
    “…This paper proposes a progressive unsupervised driving anomaly detection and recounting (D&R) framework. The highlights are three-fold: (1) We formulate driving anomaly D&R as a temporal-spatial-semantic (TSS) model, which achieves a coarse-to-fine focusing and generates convincing driving anomaly D&R. (2) This work contributes an unsupervised D&R without any training data while performing an effective performance. (3) We novelly introduce the traffic saliency, isolation forest, visual semantic causal relations of driving scene to effectively construct the TSS model. …”
