Comments on "Iteratively Re-weighted Algorithm for Fuzzy c-Means"
Astha Saini, Prabhu Babu
In this comment, we present a simple alternate derivation to the IRW-FCM algorithm presented in "Iteratively Re-weighted Algorithm for Fuzzy c-Means" for Fuzzy c-Means problem. We…
Majorization-Minimization based Hybrid Localization Method for High Precision Localization in Wireless Sensor Networks
Kuntal Panwar, Prabhu Babu, R. Jyothi
This paper investigates the hybrid source localization problem using the four radio measurements - time of arrival (TOA), time difference of arrival (TDOA), received signal strengt…
Optimal Sensor Placement for Hybrid Source Localization Using Fused TOA-RSS-AOA Measurements
Kuntal Panwar, Ghania Fatima, Prabhu Babu
Source localization techniques incorporating hybrid measurements improve the reliability and accuracy of the location estimate. Given a set of hybrid sensors that can collect combi…
Learning Sparse Graphs via Majorization-Minimization for Smooth Node Signals
Ghania Fatima, Aakash Arora, Prabhu Babu +1
In this letter, we propose an algorithm for learning a sparse weighted graph by estimating its adjacency matrix under the assumption that the observed signals vary smoothly over th…
