Cae-If: An Anomaly Detection Approach Based On Temporal Representation Of The Reconstruction Error, Haijun Geng, Zhi Zhang, Yuhua Qian, Bo Yang, Qi Ma, Haotian Chi, Jing Yang, Xia Yin

Faculty Research, Scholarly, and Creative Activity

In the field of network traffic anomaly detection, unsupervised learning plays a critical role yet encounters significant challenges, including accurately determining anomaly thresholds and modeling the intricate temporal dynamics of network traffic. To address these challenges, we present a novel approach, termed Convolutional Autoencoder-Isolation Forest (CAE-IF). By leveraging packet-level reconstruction errors with contextual information, our approach obviates the need for manual threshold setting and effectively captures temporal dynamics. The process commences with the application of the damped incremental statistics algorithm to extract statistical features from network traffic with temporal information. Subsequently, the Convolutional Autoencoder (CAE) is employed to compute the …

How Localized Physical Processes Influence Large-Scale Phytoplankton Blooms Near The Sea Ice Edge In The Greenland Sea, Abigail P. Heiser, Till J.W. Wagner, Manfredi Manizza, Dustin Carroll, Conner W. Lester, Dimitris Menemenlis

Faculty Research, Scholarly, and Creative Activity

The Arctic Ocean has experienced intensifying phytoplankton spring blooms near the sea ice edge. Here, we investigate the drivers of such near-ice blooms in the Greenland Sea by comparing satellite and in situ observations with the ECCO-Darwin physical–biogeochemical state estimate. Satellite data reveal pronounced spring blooms within ~ 200 km of the ice, a signal that is not reproduced in ECCO-Darwin. Observations further reveal that primary production is tightly linked to submesoscale meltwater eddies shed from the ice edge, which are not currently resolved by ECCO-Darwin. We argue that the relatively coarse spatial resolution, together with biases in sea ice …

Match Made In Ml: Developing Compatibility Relationships In Evidential Reasoning Approaches With Machine Learning, Ella Jolie Thomas

Master's Theses

The presented expectation maximization informed evidential reasoning model extends the ability of the evidential reasoning calculus to support decision making by integrating an adaptive model learning capability. Compatibility relationships in Evidential Reasoning models are traditionally built by human domain experts. This process is labor-intensive, especially for large and complex models. Additionally, when new data becomes available, compatibility relationships must be reconstructed. Using machine learning and the expectation maximization algorithm, it is demonstrated that compatibility relationships can be constructed that learn relationships between domain knowledge that is used to make decisions. Using drug development as a domain of application, a traditional …
