We evaluate how modern outlier detection methods perform in identifying outliers in e-commerce conversion rate data. Based on the limitations identified, we then present a novel method to detect outliers in e-commerce conversion rate. This unsupervised method is made more business relevant by letting it automatically a…

Method identifies over-optimized adversarial examples using IQR-based logit thresholding.
problem Over-optimized adversarial examples are hard to detect due to model optimization.
method IQR-based logit thresholding method for identifying over-optimized adversarial examples.
result The logits of the model are more useful in detecting over-optimized adversarial examples.
A main goal of regression is to derive statistical conclusions on the conditional distribution of the output variable Y given the input values x. Two of the most important characteristics of a single distribution are location and scale. Support vector machines (SVMs) are well established to estimate location functions …
Circular transformation of the European steel industry renders scrap metal a strategic resourceq-fin.TR
European steel industry shifts to electric arc furnaces, reducing scrap imports and increasing competition.
problem Reducing CO2 emissions in the European steel industry through electric arc furnaces.
method Combining trade data with business intelligence to model the impact of EAF capacity on scrap trade.
result Scrap imports decrease as EAF capacity increases, highlighting the need for a new business ecosystem.
