Towards Statistically Significant Taxonomy Aware Co-location Pattern Detection

no code implementations29 Jun 2024 Subhankar Ghosh, Arun Sharma, Jayant Gupta, Shashi Shekhar

Given a collection of Boolean spatial feature types, their instances, a neighborhood relation (e. g., proximity), and a hierarchical taxonomy of the feature types, the goal is to find the subsets of feature types or their parents whose spatial interaction is statistically significant.

Conformal Prediction for Class-wise Coverage via Augmented Label Rank Calibration

no code implementations10 Jun 2024 Yuanjie Shi, Subhankar Ghosh, Taha Belkhouja, Janardhan Rao Doppa, Yan Yan

In contrast to the standard class-conditional CP (CCP) method that uniformly thresholds the class-wise conformity score for each class, the augmented label rank calibration step allows RC3P to selectively iterate this class-wise thresholding subroutine only for a subset of classes whose class-wise top-k error is small.

FAST: Font-Agnostic Scene Text Editing

no code implementations5 Aug 2023 Alloy Das, Prasun Roy, Saumik Bhattacharya, Subhankar Ghosh, Umapada Pal, Michael Blumenstein

However, most of the existing STE methods show inferior editing performance because of (1) complex image backgrounds, (2) various font styles, and (3) varying word lengths within the text.
