Hace 4 días · Como científico de datos, tiene la tarea de garantizar la integridad de los datos antes de sumergirse en cualquier análisis importante. Esto implica identificar y abordar cualquier irregularidad en su conjunto de datos que pueda distorsionar sus hallazgos. Ya sea que estas anomalías sean valores atípicos, errores o incoherencias, su impacto ...
Hace 2 días · 1 INTRODUCTION. Anomaly detection refers to identifying patterns that do not conform to expected normal behaviour [].It is a critical subject with broad applications across various industries, playing a key role in diverse domains such as network security [], intrusion detection [] and fraud detection [].The task of anomaly detection is challenging due to the rarity of abnormal samples and ...
Hace 3 días · Rotorcrafts experience severe vibrations during operation. To ensure the safety of rotorcrafts, it is necessary to perform anomaly detection to detect small-scale structural faults in major components. To accurately detect small-scale faults before they grow to a fatal size, HR (high sampling rate) vibration data are required. However, to increase the efficiency of data storage media, only LR ...
Hace 2 días · Extensive experiments on large EHR datasets across various medical domains demonstrate that EHR-BERT markedly improves upon existing models. It significantly reduces the number of false positives and enhances the detection rate, thus bolstering the reliability of anomaly detection in electronic health records.

Hace 2 días · The kaleidoscopic rainbow taking flight over St. Pete isn't an exotic bird or refraction of light. It's the "Mooney Anomaly," a four-passenger plane turned flying mural.Why it matters: Artist Matt Kress and pilot Liam Hawkins almost didn't get their dreams off the ground. They hope the "Anomaly" inspires others to follow theirs.
Hace 3 días · The issues investigated in this study include (1) the presence of ambiguous data that cannot be categorized as an anomaly class in the literature, (2) information loss during the conversion of time-series data into images for the deep-learning-based approach, and (3) additional issues, such as misclassification by trained models and ...
