A Contrastive Fewshot RGBD Traversability Segmentation Framework for Indoor Robotic Navigation
Qiyuan An, Tuan Dang, Fillia Makedon
Indoor traversability segmentation aims to identify safe, navigable free space for autonomous agents, which is critical for robotic navigation. Pure vision-based models often fail…
Enhancing Robustness of Indoor Robotic Navigation with Free-Space Segmentation Models Against Adversarial Attacks
Qiyuan An, Christos Sevastopoulos, Fillia Makedon
Endeavors in indoor robotic navigation rely on the accuracy of segmentation models to identify free space in RGB images. However, deep learning models are vulnerable to adversarial…
Depth-guided Free-space Segmentation for a Mobile Robot
Christos Sevastopoulos, Joey Hussain, Stasinos Konstantopoulos +2
Accurate indoor free-space segmentation is a challenging task due to the complexity and the dynamic nature that indoor environments exhibit. We propose an indoors free-space segmen…
Assessing Fatigue with Multimodal Wearable Sensors and Machine Learning
Ashish Jaiswal, Mohammad Zaki Zadeh, Aref Hebri +1
Fatigue is a loss in cognitive or physical performance due to physiological factors such as insufficient sleep, long work hours, stress, and physical exertion. It adversely affects…
Sequential Late Fusion Technique for Multi-modal Sentiment Analysis
Debapriya Banerjee, Fotios Lygerakis, Fillia Makedon
Multi-modal sentiment analysis plays an important role for providing better interactive experiences to users. Each modality in multi-modal data can provide different viewpoints or…
Towards a Multi-purpose Robotic Nursing Assistant
Krishna Chaitanya Kodur, Kaustubh Rajpathak, Akilesh Rajavenkatanarayanan +2
Robotic nursing aid is one of the heavily researched areas in robotics nowadays. Several robotic assistants exist that only focus on a specific function related to nurses assistanc…
Understanding Cognitive Fatigue from fMRI Scans with Self-supervised Learning
Ashish Jaiswal, Ashwin Ramesh Babu, Mohammad Zaki Zadeh +2
Functional magnetic resonance imaging (fMRI) is a neuroimaging technique that records neural activations in the brain by capturing the blood oxygen level in different regions based…
Automated system to measure Tandem Gait to assess executive functions in children
Mohammad Zaki Zadeh, Ashwin Ramesh Babu, Ashish Jaiswal +3
As mobile technologies have become ubiquitous in recent years, computer-based cognitive tests have become more popular and efficient. In this work, we focus on assessing motor func…
A Survey on Contrastive Self-supervised Learning
Ashish Jaiswal, Ashwin Ramesh Babu, Mohammad Zaki Zadeh +2
Self-supervised learning has gained popularity because of its ability to avoid the cost of annotating large-scale datasets. It is capable of adopting self-defined pseudo labels as…
Self-Supervised Human Activity Recognition by Augmenting Generative Adversarial Networks
Mohammad Zaki Zadeh, Ashwin Ramesh Babu, Ashish Jaiswal +1
This article proposes a novel approach for augmenting generative adversarial network (GAN) with a self-supervised task in order to improve its ability for encoding video representa…
Using Humanoid Robot to Instruct and Evaluate Performance of a Physical Task
Shawn N. Gieser, Joseph Tompkins, Ali Sharifara +1
In this paper, we present a tool to assess users ability to change tasks. To do this, we use a variation of the Box and Blocks Test. In this version, a humanoid robot instructs a u…
Towards Deep Learning based Hand Keypoints Detection for Rapid Sequential Movements from RGB Images
Srujana Gattupalli, Ashwin Ramesh Babu, James Robert Brady +2
Hand keypoints detection and pose estimation has numerous applications in computer vision, but it is still an unsolved problem in many aspects. An application of hand keypoints det…
Improving the Accuracy of the CogniLearn System for Cognitive Behavior Assessment
Amir Ghaderi, Srujana Gattupalli, Dylan Ebert +3
HTKS is a game-like cognitive assessment method, designed for children between four and eight years of age. During the HTKS assessment, a child responds to a sequence of requests,…
