Enhancing Classification with Hierarchical Scalable Query on Fusion Transformer

no code implementations28 Feb 2023 Sudeep Kumar Sahoo, Sathish Chalasani, Abhishek Joshi, Kiran Nanjunda Iyer

We additionally introduce a novel block called Cross Attention on Multi-level queries with Prior (CAMP) Block that helps reduce error propagation from coarse level to finer level, which is a common problem in all hierarchical classifiers.

Robust Perception through Equivariance

1 code implementation12 Dec 2022 Chengzhi Mao, Lingyu Zhang, Abhishek Joshi, Junfeng Yang, Hao Wang, Carl Vondrick

In this paper, we introduce a framework that uses the dense intrinsic constraints in natural images to robustify inference.

Semantic Driven Energy based Out-of-Distribution Detection

no code implementations23 Aug 2022 Abhishek Joshi, Sathish Chalasani, Kiran Nanjunda Iyer

We achieve it by minimizing the energy for in-distribution samples and simultaneously learn respective class representations that are closer and maximizing energy for out-distribution samples and pushing their representation further out from known class representation.

SHAD3S: A model to Sketch, Shade and Shadow

2 code implementations13 Nov 2020 Raghav B. Venkataramaiyer, Abhishek Joshi, Saisha Narang, Vinay P. Namboodiri

Hatching is a common method used by artists to accentuate the third dimension of a sketch, and to illuminate the scene.

Unsupervised Synthesis of Anomalies in Videos: Transforming the Normal

no code implementations14 Apr 2019 Abhishek Joshi, Vinay P. Namboodiri

Finally through this synthesis approach we obtain a comparable set of abnormal samples that can be used for training the CNN for the classification of normal vs abnormal samples.
