High-Resolution Satellite Imagery for Modeling the Impact of Aridification on Crop Production

no code implementations25 Sep 2022 Depanshu Sani, Sandeep Mahato, Parichya Sirohi, Saket Anand, Gaurav Arora, Charu Chandra Devshali, Thiagarajan Jayaraman, Harsh Kumar Agarwal

We also propose a yield prediction strategy that uses time-series data generated based on the observed growing season and the standard seasonal information obtained from Tamil Nadu Agricultural University for the region.

Learning Hierarchy Aware Features for Reducing Mistake Severity

1 code implementation26 Jul 2022 Ashima Garg, Depanshu Sani, Saket Anand

In this paper, we propose a novel approach for learning Hierarchy Aware Features (HAF) that leverages classifiers at each level of the hierarchy that are constrained to generate predictions consistent with the label hierarchy.

A Deep Learning Approach To Estimation Using Measurements Received Over a Network

no code implementations20 Jan 2022 Shivangi Agarwal, Sanjit K. Kaul, Saket Anand, P. B. Sujit

The measurements are communicated over a network as packets, at a rate unknown to the estimator.

HIERMATCH: Leveraging Label Hierarchies for Improving Semi-Supervised Learning

1 code implementation30 Oct 2021 Ashima Garg, Shaurya Bagga, Yashvardhan Singh, Saket Anand

Additionally, HIERMATCH is a generic-approach to improve any semisupervised learning framework, we demonstrate this using our results on recent state-of-the-art techniques MixMatch and FixMatch.

Does Data Repair Lead to Fair Models? Curating Contextually Fair Data To Reduce Model Bias

1 code implementation20 Oct 2021 Sharat Agarwal, Sumanyu Muku, Saket Anand, Chetan Arora

Through a series of experiments, we validate that curating contextually fair data helps make model predictions fair by balancing the true positive rate for the protected class across groups without compromising on the model's overall performance.

Contextual Diversity for Active Learning

1 code implementation ECCV 2020 Sharat Agarwal, Himanshu Arora, Saket Anand, Chetan Arora

Contextual Diversity (CD) hinges on a crucial observation that the probability vector predicted by a CNN for a region of interest typically contains information from a larger receptive field.

GraCIAS: Grassmannian of Corrupted Images for Adversarial Security

no code implementations6 May 2020 Ankita Shukla, Pavan Turaga, Saket Anand

In this work, we propose a defense strategy that applies random image corruptions to the input image alone, constructs a self-correlation based subspace followed by a projection operation to suppress the adversarial perturbation.

Automatic Detection and Recognition of Individuals in Patterned Species

no code implementations6 May 2020 Gullal Singh Cheema, Saket Anand

Pseudo RGB-D for Self-Improving Monocular SLAM and Depth Prediction

no code implementations ECCV 2020 Lokender Tiwari, Pan Ji, Quoc-Huy Tran, Bingbing Zhuang, Saket Anand, Manmohan Chandraker

Classical monocular Simultaneous Localization And Mapping (SLAM) and the recently emerging convolutional neural networks (CNNs) for monocular depth prediction represent two largely disjoint approaches towards building a 3D map of the surrounding environment.

Primate Face Identification in the Wild

no code implementations3 Jul 2019 Ankita Shukla, Gullal Singh Cheema, Saket Anand, Qamar Qureshi, Yadvendradev Jhala

This loss of habitat has skewed the population of several non-human primate species like chimpanzees and macaques and has constrained them to co-exist in close proximity of human settlements, often leading to human-wildlife conflicts while competing for resources.

Geometry of Deep Generative Models for Disentangled Representations

no code implementations19 Feb 2019 Ankita Shukla, Shagun Uppal, Sarthak Bhagat, Saket Anand, Pavan Turaga

We use several metrics to compare the properties of latent spaces of disentangled representation models in terms of class separability and curvature of the latent-space.
