Akshita Guptaअक्षिता गुप्ता

I am a Data Scientist at Bayanat , here I work on projects broadly related to Detection and Segmentation domains. Previously, I was a research engineer at Inception Institute of Artificial Intelligence working with Dr Sanath Narayan ,Dr Salman Khan and Dr Fahad Shahbaz Khan. At IIAI, I worked on research projects dealing with Open world and zero-shot object Detection, Generative Adversarial Networks and Few- and Zero- shot Learning problems. I also work on industrial projects which try to solve Texture Classification, Object Detection and Object Counting problems.

I was fortunate to spend a semester during my undergraduate studies at Indian Institute of Technology Roorkee, where I was supervised by Dr. Balasubramanian Raman. Parrallel to my semester at IIT, I was selected as a outreachy intern, with Mozilla (2018), where I was supervised by Emma Irwin

Research

I'm interested in developing models which can learn with limited data and few, zero or one training sample(s).

OW-DETR: Open-world Detection Transformer
Akshita Gupta*, Sanath Narayan*, Joseph KJ, Salman Khan, Fahad Shahbaz Khan,
Mubarak Shah
CVPR 2022
paper / code
  • Description: Developed multi-scale context aware detection framework with attention-driven psuedo-labelling.
  • Outcome: Improved state-of-the-art performances on MS-COCO dataset with absolute gains ranging from 1.8% to 3.3% in terms of unknown recall.
Discriminative Region-based Multi-Label Zero-Shot Learning
Sanath Narayan*, Akshita Gupta*, Salman Khan, Fahad Shahbaz Khan,
Ling Shao, Mubarak Shah
ICCV 2021
paper / code
  • Description: Developed a attention module which combines both region-level and global-level contextual information.
  • Outcome: Improved state-of-the-art performances on NUS-WIDE, OpenImages by 6.9% and 31.9% mAP score.
Generative Multi-Label Zero-Shot Learning
Akshita Gupta*, Sanath Narayan*, Salman Khan, Fahad Shahbaz Khan,
Ling Shao, Joost van de Weijer
Under Review in TPAMI
paper / code
  • Description: Developed a generative model that constructs multi-label features for (generalized) zero-shot learning.
  • Outcome: Improved state-of-the-art performances on NUS-WIDE, OpenImages and MS-COCO by 3.3%, 4.3% and 15.7% mAP score.
Latent Embedding Feedback and Discriminative Features for Zero-Shot Classification
Sanath Narayan*, Akshita Gupta*, Salman Khan, Fahad Shahbaz Khan,
Cees G. M. Snoek, Ling Shao,
ECCV 2020
paper / code
  • Description: Developed a generative feature synthesizing framework for zero-shot learning.
  • Outcome: Improved state-of-the-art performances on CUB, FLO, SUN, and AWA by 4.6%, 7.1%, 1.7%, and 3.1% harmonic mean by enforcing semantic consistency at all stages of zero-shot learning.
iSAID: A Large-scale Dataset for Instance Segmentation in Aerial Images
Syed Waqas Zamir, Aditya Arora, Akshita Gupta, Salman Khan, Guolei Sun, Fahad Shahbaz Khan, Fan Zhu, Ling Shao, Gui-Song Xia, Xiang Bai
CVPR Workshop 2019 (Oral Presentation)
code / dataset
  • Description: Improved state of the art object detector (Mask-RCNN and PANet) for aerial imagery.
  • Outcome: Proposed a large scale instance segmentation and object detection dataset (iSAID) with benchmarking on mask-RCNN and PANet.
Acoustic features fusion using attentive multi-channel deep architecture
Gaurav Bhatt, Akshita Gupta, Aditya Arora, Balasubramanian Raman
Interspeech Workshop 2018
code
  • Description: Developed an attention based framework for acoustic scene recognition and audio tagging.
  • Outcome: Improved the equal error rate by atleast 3% over the Dcase challenge results.
