Achieving More with Less: Learning Generalizable Neural Networks With Less Labeled Data and Computational Overheads
… datasets and using highly compute-intensive models. Many applications cannot afford these costs needed to ensure generalizability of deep learning models. For instance, obtaining labeled data can be costly in scientific applications, and using large models may not be feasible in …

Detecting Bots using Stream-based System with Data Synthesis
… bot detection. However, many machine learning models are difficult to deploy since model training requires the continuous supply of representative labeled data, which are expensive and time-consuming to obtain in practice. In this thesis, we build a bot detection system with a data synthesis …

Weisfeiler-Leman graph kernels for the out-of-distribution characterization of graph structured data
… Neural Networks (GNNs) without introducing a new model architecture. Within existing GNN research, strong claims of out-of-distribution (OOD) generalizability are frequently made, but these claims fail when exposed to real-world data. We propose existing standards of identifying OOD data are …
