3D Face Style Transfer with a Hybrid Solution of NeRF and Mesh Rasterization

no code implementations22 Nov 2023 Jianwei Feng, Prateek Singhal

We therefore propose a hybrid framework of NeRF and mesh rasterization to combine the benefits of high fidelity geometry reconstruction of NeRF and fast rendering speed of mesh.

Language Grounded QFormer for Efficient Vision Language Understanding

no code implementations13 Nov 2023 Moulik Choraria, Nitesh Sekhar, Yue Wu, Xu Zhang, Prateek Singhal, Lav R. Varshney

Large-scale pretraining and instruction tuning have been successful for training general-purpose language models with broad competencies.

Representation Learning

Avoiding spurious correlations via logit correction

1 code implementation2 Dec 2022 Sheng Liu, Xu Zhang, Nitesh Sekhar, Yue Wu, Prateek Singhal, Carlos Fernandez-Granda

Empirical studies suggest that machine learning models trained with empirical risk minimization (ERM) often rely on attributes that may be spuriously correlated with the class labels.


Multi-modal Tracking for Object based SLAM

no code implementations14 Mar 2016 Prateek Singhal, Ruffin White, Henrik Christensen

We present an on-line 3D visual object tracking framework for monocular cameras by incorporating spatial knowledge and uncertainty from semantic mapping along with high frequency measurements from visual odometry.

Dynamic Body VSLAM with Semantic Constraints

no code implementations27 Apr 2015 N. Dinesh Reddy, Prateek Singhal, Visesh Chari, K. Madhava Krishna

We show results on the challenging KITTI urban dataset for accuracy of motion segmentation and reconstruction of the trajectory and shape of moving objects relative to ground truth.
