GenEARL: A Training-Free Generative Framework for Multimodal Event Argument Role Labeling

Hritik Bansal, Po-Nien Kung, P. Jeffrey Brantingham +2

Multimodal event argument role labeling (EARL), a task that assigns a role for each event participant (object) in an image is a complex challenge. It requires reasoning over the en…

Bridging Knowledge Graphs to Generate Scene Graphs

Alireza Zareian, Svebor Karaman, Shih-Fu Chang

Scene graphs are powerful representations that parse images into their abstract semantic elements, i.e., objects and their interactions, which facilitates visual comprehension and…

Unsupervised Rank-Preserving Hashing for Large-Scale Image Retrieval

Svebor Karaman, Xudong Lin, Xuefeng Hu +1

We propose an unsupervised hashing method which aims to produce binary codes that preserve the ranking induced by a real-valued representation. Such compact hash codes enable the c…

Multi-level Multimodal Common Semantic Space for Image-Phrase Grounding

Hassan Akbari, Svebor Karaman, Surabhi Bhargava +3

We address the problem of phrase grounding by lear ing a multi-level common semantic space shared by the textual and visual modalities. We exploit multiple levels of feature maps o…

Heated-Up Softmax Embedding

Xu Zhang, Felix Xinnan Yu, Svebor Karaman +2

Metric learning aims at learning a distance which is consistent with the semantic meaning of the samples. The problem is generally solved by learning an embedding for each sample s…
