The Generalized Friendship Paradox for Eigenvectors
Bishakh Bhattacharya, Arijit Chakrabarty, Rajat Subhra Hazra
In this paper, we investigate the generalized friendship paradox for eigenvectors (alternatively called the eigen friendship paradox and abbreviated hereafter as EFP) in the settin…
Human vs. NAO: A Computational-Behavioral Framework for Quantifying Social Orienting in Autism and Typical Development
Vartika Narayani Srinet, Anirudha Bhattacharjee, Braj Bhushan +1
Responding to one's name is among the earliest-emerging social orienting behaviors and is one of the most prominent aspects in the detection of Autism Spectrum Disorder (ASD). Typi…
Outlier eigenvalues and eigenvectors of generalized Wigner matrices with finite-rank perturbations
Bishakh Bhattacharya, Arijit Chakrabarty, Rajat Subhra Hazra
A generalized Wigner matrix perturbed by a finite-rank deterministic matrix is considered. The fluctuations of the largest eigenvalues, which emerge outside the bulk of the spectru…
A Hybrid Deep Learning Framework for Emotion Recognition in Children with Autism During NAO Robot-Mediated Interaction
Indranil Bhattacharjee, Vartika Narayani Srinet, Anirudha Bhattacharjee +2
Understanding emotional responses in children with Autism Spectrum Disorder (ASD) during social interaction remains a critical challenge in both developmental psychology and human-…
A Novel Approach to Tomato Harvesting Using a Hybrid Gripper with Semantic Segmentation and Keypoint Detection
Shahid Ansari, Mahendra Kumar Gohil, Yusuke Maeda +1
This paper presents an autonomous tomato-harvesting system built around a hybrid robotic gripper that combines six soft auxetic fingers with a rigid exoskeleton and a latex basket…
Hybrid Robotic Meta-gripper for Tomato Harvesting: Analysis of Auxetic Structures with Lattice Orientation Variations
Shahid Ansari, Vivek Gupta, Bishakh Bhattacharya
The agricultural sector is rapidly evolving to meet growing global food demands, yet tasks like fruit and vegetable handling remain labor-intensive, causing inefficiencies and post…
