Improving Code Localization with Repository Memory

ICLR 2026poster

Code localization is a fundamental challenge in repository-level software engineering tasks such as bug fixing. While existing methods equip language agents with comprehensive tools/interfaces to fetch information from the repository, they overlook the critical aspect of *memory*, where each instanc…

Olympus: A Universal Task Router for Computer Vision Tasks

CVPR 2025highlight

We introduce Olympus, a new approach that transforms Multimodal Large Language Models (MLLMs) into a unified framework capable of handling a wide array of computer vision tasks. Utilizing a controller MLLM, Olympus delegates over 20 specialized tasks across images, videos, and 3D objects to dedicate…

Florence-2: Advancing a Unified Representation for a Variety of Vision Tasks

CVPR 2024poster

We introduce Florence-2 a novel vision foundation model with a unified prompt-based representation for various computer vision and vision-language tasks. While existing large vision models excel in transfer learning they struggle to perform diverse tasks with simple instructions a capability that im…

Convolutions and Self-Attention: Re-interpreting Relative Positions in Pre-trained Language Models

ACL 2021long

In this paper, we detail the relationship between convolutions and self-attention in natural language tasks. We show that relative position embeddings in self-attention layers are equivalent to recently-proposed dynamic lightweight convolutions, and we consider multiple new ways of integrating convo…

Guided Variational Autoencoder for Disentanglement Learning

CVPR 2020poster

We propose an algorithm, guided variational autoencoder (Guided-VAE), that is able to learn a controllable generative model by performing latent representation disentanglement learning. The learning objective is achieved by providing signal to the latent encoding/embedding in VAE without changing it…
