Learnable Spatio-Temporal Map Embeddings for Deep Inertial Localization

no code implementations14 Nov 2022 Dennis Melamed, Karnik Ram, Vivek Roy, Kris Kitani

To address the robustness problem in map utilization, we propose a data-driven prior on possible user locations in a map by combining learned spatial map embeddings and temporal odometry embeddings.

DeepBLE: Generalizing RSSI-based Localization Across Different Devices

no code implementations27 Feb 2021 Harsh Agarwal, Navyata Sanghvi, Vivek Roy, Kris Kitani

Accurate smartphone localization (< 1-meter error) for indoor navigation using only RSSI received from a set of BLE beacons remains a challenging problem, due to the inherent noise of RSSI measurements.

Few-Shot Learning with Intra-Class Knowledge Transfer

no code implementations22 Aug 2020 Vivek Roy, Yan Xu, Yu-Xiong Wang, Kris Kitani, Ruslan Salakhutdinov, Martial Hebert

Recent works have proposed to solve this task by augmenting the training data of the few-shot classes using generative models with the few-shot training samples as the seeds.
