SEGRA: Structured Experience-Guided Graph Reasoning Agent for Gremlin Based Question Answering

Saiyue Lyu, Mariam Dundua, Vishaal Kapoor +5

Enterprise IT support knowledge graphs capture rich relationships among cases, users, devices, symptoms, taxonomic categories, root causes, and historical resolutions. Yet querying…

ReDiTT: Retrieval Augmented Conditional Diffusion Transformers for Asynchronous Time Series

Saiyue Lyu, Zhitian Zhang, Ruizhi Deng +1

The paper proposes ReDiTT, a diffusion‑based conditional transformer that retrieves similar latent sequences from a memory bank to improve prediction of the next event time and typ…

Adaptive Diffusion Denoised Smoothing : Certified Robustness via Randomized Smoothing with Differentially Private Guided Denoising Diffusion

Frederick Shpilevskiy, Saiyue Lyu, Krishnamurthy Dj Dvijotham +2

We propose Adaptive Diffusion Denoised Smoothing, a method for certifying the predictions of a vision model against adversarial examples, while adapting to the input. Our key insig…

Adaptive Randomized Smoothing: Certified Adversarial Robustness for Multi-Step Defences

Saiyue Lyu, Shadab Shaikh, Frederick Shpilevskiy +2

We propose Adaptive Randomized Smoothing (ARS) to certify the predictions of our test-time adaptive models against adversarial examples. ARS extends the analysis of randomized smoo…

DP-LDMs: Differentially Private Latent Diffusion Models

Michael F. Liu, Saiyue Lyu, Margarita Vinaroz +1

Diffusion models (DMs) are one of the most widely used generative models for producing high quality images. However, a flurry of recent papers points out that DMs are least private…
