Improving Ground-Based Measurements And Understanding Of Mineral Dust And Trace Elements In Ambient Particulate Matter On A Global Scale, Xuan Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Mineral dust is a major component of ambient particulate matter (PM) globally, affecting visibility, air quality, human health, climate, and biogeochemistry. Dust mass cannot be directly measured and therefore is typically estimated using a dust equation to sum common oxides of major crustal elements based on measured elemental composition data. Both an accurate dust equation and reliable elemental data are essential to accurately estimate dust mass. However, most dust equations fail to account for all major dust compounds, exclude non-dust components of some elements, or account for regional variations in dust composition. Attenuation effects for light elements measured by the …

Interpreting Black-Box Time Series Classifiers Using Parameterised Event Primitives, Ephrem Tibebe Mekonnen, Luca Longo, Pierpaolo Dondio

Conference papers

Amidst the remarkable performance of deep learning models in time series classification, there is a pressing demand for methods that unveil their prediction rationale. Existing feature importance techniques often neglect the temporal nature of time series data, focusing solely on segment importance. Addressing this gap, this paper introduces a local model-agnostic method akin to LIME, which generates neighbouring samples by randomly perturbing segments of the original instance. Subsequently, weights are computed for each neighbouring instance based on its distance from the original, elucidating its influence. Parameterised event primitives (PEPs) are then extracted from these perturbed samples, encompassing increasing and decreasing …
