An Architecture for Person-Following using Active Target Search [article]

Minkyu Kim, Miguel Arduengo, Nick Walker, Yuqian Jiang, Justin W. Hart, Peter Stone, Luis Sentis
2018 arXiv   pre-print
This paper addresses a novel architecture for person-following robots using active search.  ...  Toward this end, an active target searching capability, including prediction and navigation toward vantage locations for finding human targets, is proposed.  ...  This information can be used as an important clue for robots to follow or search for target objects. To compute where a robot is headed, a person-following algorithm is described in Algorithm 1.  ...

Learning Generalisable Omni-Scale Representations for Person Re-Identification [article]

Kaiyang Zhou, Yongxin Yang, Andrea Cavallaro, Tao Xiang
2021 arXiv   pre-print
Further, to determine the optimal placements of these IN layers in the architecture, we formulate an efficient differentiable architecture search algorithm.  ...  An effective person re-identification (re-ID) model should learn feature representations that are both discriminative, for distinguishing similar-looking people, and generalisable, for deployment across  ...  To this end, we use a width multiplier 4 and an image resolution multiplier, following [11] , [12] , [54] .

Joint Learning of Neural Transfer and Architecture Adaptation for Image Recognition [article]

Guangrun Wang and Liang Lin and Rongcong Chen and Guangcong Wang and Jiqi Zhang
2021 arXiv   pre-print
However, each domain with a distinct recognition target may need different levels/paths of feature hierarchy, where some neurons may become redundant, and some others are re-activated to form new network  ...  Moreover, we also provide principled and empirical analysis to explain why our approach works by investigating the ineffectiveness of existing neural architecture search.  ...  In particular, the target architecture is searched for on the target task (i.e., person re-ID).  ...
