On Characterizing the Evolution of Embedding Space of Neural Networks using Algebraic Topology
Suryaka Suresh, Bishshoy Das, Vinayak Abrol +1
We study how the topology of feature embedding space changes as it passes through the layers of a well-trained deep neural network (DNN) through Betti numbers. Motivated by existin…
Altering Backward Pass Gradients improves Convergence
Bishshoy Das, Milton Mondal, Brejesh Lall +2
In standard neural network training, the gradients in the backward pass are determined by the forward pass. As a result, the two stages are coupled. This is how most neural network…
DFCANet: Dense Feature Calibration-Attention Guided Network for Cross Domain Iris Presentation Attack Detection
Gaurav Jaswal, Aman Verma, Sumantra Dutta Roy +1
An iris presentation attack detection (IPAD) is essential for securing personal identity is widely used iris recognition systems. However, the existing IPAD algorithms do not gener…
Sensor-invariant Fingerprint ROI Segmentation Using Recurrent Adversarial Learning
Indu Joshi, Ayush Utkarsh, Riya Kothari +4
A fingerprint region of interest (roi) segmentation algorithm is designed to separate the foreground fingerprint from the background noise. All the learning based state-of-the-art…
Data Uncertainty Guided Noise-aware Preprocessing Of Fingerprints
Indu Joshi, Ayush Utkarsh, Riya Kothari +4
The effectiveness of fingerprint-based authentication systems on good quality fingerprints is established long back. However, the performance of standard fingerprint matching syste…
Early Detection of Parkinson's Disease through Patient Questionnaire and Predictive Modelling
R Prashanth, Sumantra Dutta Roy
Early detection of Parkinson's disease (PD) is important which can enable early initiation of therapeutic interventions and management strategies. However, methods for early detect…
Novel and Improved Stage Estimation in Parkinson's Disease using Clinical Scales and Machine Learning
R. Prashanth, Sumantra Dutta Roy
The stage and severity of Parkinson's disease (PD) is an important factor to consider for taking effective therapeutic decisions. Although the Movement Disorder Society-Unified Par…
Extraction of Layout Entities and Sub-layout Query-based Retrieval of Document Images
Anukriti Bansal, Sumantra Dutta Roy, Gaurav Harit
Layouts and sub-layouts constitute an important clue while searching a document on the basis of its structure, or when textual content is unknown/irrelevant. A sub-layout specifies…
