Improving Generalization via Meta-Learning on Hard Samples

no code implementations CVPR 2024 Nishant Jain, Arun S. Suggala, Pradeep Shenoy

In particular, we show that using hard-to-classify instances in the validation set has both a theoretical connection to, and strong empirical evidence of generalization.

Learning Robust Multi-Scale Representation for Neural Radiance Fields from Unposed Images

no code implementations8 Nov 2023 Nishant Jain, Suryansh Kumar, Luc van Gool

The key ideas presented in this paper are (i) Recovering accurate camera parameters via a robust pipeline from unposed day-to-day images is equally crucial in neural novel view synthesis problem; (ii) It is rather more practical to model object's content at different resolutions since dramatic camera motion is highly likely in day-to-day unposed images.

Selective classification using a robust meta-learning approach

no code implementations12 Dec 2022 Nishant Jain, Karthikeyan Shanmugam, Pradeep Shenoy

Predictive uncertainty-a model's self awareness regarding its accuracy on an input-is key for both building robust models via training interventions and for test-time applications such as selective classification.

Instance-Conditional Timescales of Decay for Non-Stationary Learning

no code implementations12 Dec 2022 Nishant Jain, Pradeep Shenoy

Second, we learn an auxiliary scorer model that recovers the appropriate mixture of timescales as a function of the instance itself.

Robustifying the Multi-Scale Representation of Neural Radiance Fields

no code implementations9 Oct 2022 Nishant Jain, Suryansh Kumar, Luc van Gool

Although recently proposed Mip-NeRF could handle multi-scale imaging problems with NeRF, it cannot handle camera pose estimation error.

From Fully Supervised to Zero Shot Settings for Twitter Hashtag Recommendation

no code implementations11 Jun 2019 Abhay Kumar, Nishant Jain, Suraj Tripathi, Chirag Singh

To overcome this limitation, we propose a Zero Shot Learning (ZSL) paradigm for predicting unseen hashtag labels by learning the relationship between the semantic space of tweets and the embedding space of hashtag labels.
