lessCSPAC and CSSI are excited to announce our upcoming series of events on public speaking! All are welcome and encouraged to participate. See below for details:
Public speaking workshop w/ Prof. Samir Khuller @ May 19, 12-1 PM
Come hear tips for crafting talks for various genres, audiences, and venues from Samir! Afterwards, we will split into small groups to draft, practice, and give feedback on talks. Lunch will be provided.Students at any stage in their program are highly encouraged to participate! This is a great opportunity to practice an essential research skill, share your research with others, and receive constructive feedback from supportive faculty!

What is CSPAC?We are the CS PhD Advisory Council. We are a PhD student-led organization, and our mandate is to interface between PhD students and faculty on academic issues. We want to advocate for PhD students in the department, so if there is some way we can support you, please come talk to us. We welcome PhD students to our weekly meetings on Wednesday 9:30am-10:30am in Mudd 3501 and on zoom. We also welcome anonymous concerns/feedback at any time via this form. Anyone in the community can reach us at cspac@u.northwestern.edu.

EVENT DETAILS
lessAdvanced Persistent Threats (APTs) have emerged as one of the most consequential categories of cyberattacks, causing widespread damage to enterprise infrastructure, critical systems, and national security. In response, the research community has made substantial progress in APT detection and defense, especially through the development of provenance-based intrusion detection systems (PIDS). Despite these advances, significant gaps persist between academic research and operational practice. First, complex graph-learning-based detectors incur high computational overhead, excessive detection latency, and degraded performance under the bursty, irregular workloads common in production environments. Second, the absence of systematic, scalable methods for generating realistic APT attack scenarios limits the thoroughness with which defense systems can be stress-tested. Lastly, the field continues to be constrained by the scarcity of comprehensive, realistic, and up-to-date benchmark datasets for APT intrusion detection research. This dissertation addresses these three operational gaps through ML and AI, particularly generative AI. It defines, analyzes, and proposes solutions for: (1) efficiency challenges in provenance-based intrusion detection; (2) the absence of systematic, scalable methods for generating realistic, causality-preserving APT attack scenarios for rigorous red-team evaluation; and (3) the scarcity of comprehensive, realistic, and up-to-date benchmark datasets for APT intrusion detection.

EVENT DETAILS
lessStructured schematic images—such as diagrams, maps, and puzzles—convey meaning through discrete visual elements and spatial relations. Although modern vision-language models offer strong semantic priors, they often struggle with fine-grained structure, precise relational grounding, and long-horizon state tracking. I propose a neuro-symbolic approach to schematic visual understanding centered on explicit, grounded intermediate representations.
The work builds on cognitive science accounts in which visual understanding proceeds from primitives and objects to qualitative spatial relations and task-relevant structures. It extends CogSketch, a cognitive visual-understanding system that represents scenes using glyphs and qualitative relations and links them to analogical reasoning systems such as SME, MAC/FAC, and SAGE. CogSketch plus analogy has been used in both cognitive modeling and deployed systems where the input is digital ink. This prospectus addresses the challenge of starting with images of structured semantic materials. VLMs are used as components in a representation-building pipeline that produces visual elements and spatial relations for downstream symbolic and analogical reasoning. Planned experiments to test these ideas include visual-to-formal encoding for puzzle solving, planning, and theory of mind reasoning. My claim is that explicit grounded representations offer a more interpretable, data-efficient, and reliable basis for advanced reasoning than direct end-to-end vision-language methods alone.
