Revisit Anything: Visual Place Recognition via Image Segment Retrieval

1 code implementation26 Sep 2024 Kartik Garg, Sai Shubodh Puligilla, Shishir Kolathaya, Madhava Krishna, Sourav Garg

This poses a fundamental challenge in matching two images of the same place captured from different camera viewpoints: "the similarity of what overlaps can be dominated by the dissimilarity of what does not overlap".

Keypoint Aware Masked Image Modelling

1 code implementation18 Jul 2024 Madhava Krishna, A V Subramanyam

Our method, KAMIM, improves the top-1 linear probing accuracy from 16. 12% to 33. 97%, and finetuning accuracy from 76. 78% to 77. 3% when tested on the ImageNet-1K dataset with a ViT-B when trained for the same number of epochs.

Using LLMs in Software Requirements Specifications: An Empirical Evaluation

no code implementations27 Apr 2024 Madhava Krishna, Bhagesh Gaur, Arsh Verma, Pankaj Jalote

Hence, we conclude that the LLMs can be gainfully used by software engineers to increase productivity by saving time and effort in generating, validating and rectifying software requirements.

Anticipate & Collab: Data-driven Task Anticipation and Knowledge-driven Planning for Human-robot Collaboration

no code implementations4 Apr 2024 Shivam Singh, Karthik Swaminathan, Raghav Arora, Ramandeep Singh, Ahana Datta, Dipanjan Das, Snehasis Banerjee, Mohan Sridharan, Madhava Krishna

Specifically, DaTAPlan planner computes actions for an agent and a human to collaboratively and jointly achieve the tasks anticipated by the LLM, and the agent automatically adapts to unexpected changes in human action outcomes and preferences.

EDMP: Ensemble-of-costs-guided Diffusion for Motion Planning

1 code implementation20 Sep 2023 Kallol Saha, Vishal Mandadi, Jayaram Reddy, Ajit Srikanth, Aditya Agarwal, Bipasha Sen, Arun Singh, Madhava Krishna

However, without a prior understanding of what diverse valid trajectories are and without specially designed cost functions for a given scene, the overall solutions tend to have low success rates.

AnyLoc: Towards Universal Visual Place Recognition

1 code implementation1 Aug 2023 Nikhil Keetha, Avneesh Mishra, Jay Karhade, Krishna Murthy Jatavallabhula, Sebastian Scherer, Madhava Krishna, Sourav Garg

In this work, we develop a universal solution to VPR -- a technique that works across a broad range of structured and unstructured environments (urban, outdoors, indoors, aerial, underwater, and subterranean environments) without any re-training or fine-tuning.

SCARP: 3D Shape Completion in ARbitrary Poses for Improved Grasping

no code implementations17 Jan 2023 Bipasha Sen, Aditya Agarwal, Gaurav Singh, Brojeshwar B., Srinath Sridhar, Madhava Krishna

Unlike existing methods that depend on an external canonicalization, SCARP performs canonicalization, pose estimation, and shape completion in a single network, improving the performance by 45% over the existing baselines.

Canonical Fields: Self-Supervised Learning of Pose-Canonicalized Neural Fields

1 code implementation CVPR 2023 Rohith Agaram, Shaurya Dewan, Rahul Sajnani, Adrien Poulenard, Madhava Krishna, Srinath Sridhar

We present Canonical Field Network (CaFi-Net), a self-supervised method to canonicalize the 3D pose of instances from an object category represented as neural fields, specifically neural radiance fields (NeRFs).

Object Goal Navigation using Data Regularized Q-Learning

no code implementations27 Aug 2022 Nandiraju Gireesh, D. A. Sasi Kiran, Snehasis Banerjee, Mohan Sridharan, Brojeshwar Bhowmick, Madhava Krishna

Our framework incrementally builds a semantic map of the environment over time, and then repeatedly selects a long-term goal ('where to go') based on the semantic map to locate the target object instance.
