KernelFoundry: Hardware-Aware Evolutionary GPU Kernel Optimization

ICML 2026poster

GPU kernel optimization challenges LLMs beyond standard coding tasks, as it requires an understanding of hardware architecture, parallel computing optimization strategies, and profiling outputs. However, most existing approaches leveraging LLMs for kernel generation apply standard prompting and feed…

Order Matters: 3D Shape Generation from Sequential VR Sketches

CVPR 2026

VR sketching lets users explore and iterate on ideas directly in 3D, offering a faster and more intuitive alternative to conventional CAD software. However, existing sketch-to-shape models ignore the temporal ordering of strokes, discarding crucial cues about structure and design intent. We introduc

UrbanFusion: Stochastic Multimodal Fusion for Contrastive Learning of Robust Spatial Representations

ICML 2026poster

Forecasting urban phenomena such as housing prices and public health indicators requires the effective integration of various geospatial data. Current methods primarily utilize task-specific models, while recent generic models for spatial representations often support only limited modalities and lac…

Regress, Don't Guess: A Regression-like Loss on Number Tokens for Language Models

ICML 2025poster

While language models have exceptional capabilities at text generation, they lack a natural inductive bias for emitting numbers and thus struggle in tasks involving quantitative reasoning, especially arithmetic. One fundamental limitation is the nature of the Cross Entropy loss, which assumes a nomi…

MIDGArD: Modular Interpretable Diffusion over Graphs for Articulated Designs

NeurIPS 2024poster

Providing functionality through articulation and interaction with objects is a key objective in 3D generation. We introduce MIDGArD (Modular Interpretable Diffusion over Graphs for Articulated Designs), a novel diffusion-based framework for articulated 3D asset generation. MIDGArD improves over foun…

Training Efficient Controllers via Analytic Policy Gradient

ICRA 2023poster

Control design for robotic systems is complex and often requires solving an optimization to follow a trajectory accurately. Online optimization approaches like Model Predictive Control (MPC) have been shown to achieve great tracking performance, but require high computing power. Conversely, learning…
