Hace 5 días · Anomaly detection in time series data is a crucial task with applications in various domains, from monitoring industrial systems to detecting fraudulent activities. The intricacies of time series anomalies, including early or delayed detections and varying anomaly durations, are not well captured by conventional metrics like Precision and Recall, intended for independent and identically ...
Hace 4 días · These maps show a daily sample of the along-track near-real-time (NRT) sea surface height anomaly (SSHA) measurements from the Sentinel-6 and Jason-3 satellite altimeter missions. The seasonal cycle and trend have not been removed. Each map is generated from a 10-day window of SSHA measurements. The NRT SSHA measurements from these missions are typically available within 5 to 7 hours of real time.
Hace 21 horas · To compute the non-universal correction \varepsilon we use anomaly inflow framework according to which the bulk action produces the correct amount of anomaly inflow that would cancel the anomaly of the chiral edge modes.
Hace 5 días · Plot daily composites (averages) of the mean or anomalies (mean - total mean) of variables from the NCEP/NCAR Reanalysis and other datasets. Long term means (climatologies) are based on 1991-2020. Data is available from Jan 1948 to May 26, 2024 for most variables. Enjoy! Variables. Analysis level?
Hace 3 días · A large anomaly was observed off the coast of Africa—and it has conspiracy theorists thinking that a mythical beast might be real.

Hace 2 días · A novel criterion to select the weights on aggregation of multiple models, wherein the focal loss function accounts for the classification of extremely imbalanced data is proposed, which exceeds the model averaging with typical loss functions and outstrips common anomaly detection algorithms in terms of accuracy and robustness. The effectiveness of anomaly signal detection can be significantly ...
