To Erase, or Not to Erase: Robust Training-Free Concept Erasure with Preservation aware Adaptive Ranked Subspace Expansion
Shaswati Saha, Rajasekhar Anguluri, Manas Gaur
Concept erasure techniques (CETs) edit text-to-image diffusion models to erase undesired targets such as NSFW content or copyrighted styles, while preserving model utility on benig…
A Constrained Formulation for Simultaneous Line Parameter Estimation and Instrument Transformer Calibration
Antos Cheeramban Varghese, Rajasekhar Anguluri, Anamitra Pal
The process of calibrating instrument transformers (ITs) has been greatly simplified by using phasor measurement unit (PMU) data since this process eliminates the need for (a) addi…
Alternating Minimization for Time-Shifted Synergy Extraction in Human Hand Coordination
Trevor Stepp, Parthan Olikkal, Ramana Vinjamuri +1
Identifying motor synergies -- coordinated hand joint patterns activated at task-dependent time shifts -- from kinematic data is central to motor control and robotics. Existing two…
State-Derivative Feedback Control for Damping Low-Frequency Oscillations in Bulk Power Systems
MST Rumi Akter, Anamitra Pal, Rajasekhar Anguluri
Low-frequency oscillations remain a major challenge in bulk power systems with high renewable penetration, long lines, and large loads. Existing damping strategies based on power m…
Laplacian Flows in Complex-valued Directed Networks: Analysis, Design, and Consensus
Aditi Saxena, Twinkle Tripathy, Rajasekhar Anguluri
In the interdisciplinary field of network science, a complex-valued network, with edges assigned complex weights, provides a more nuanced representation of relationships by capturi…
A Practical Approach Towards Inertia Estimation Using Ambient Synchrophasor Data
Anushka Sharma, Anamitra Pal, Rajasekhar Anguluri +1
Real-time tracking of inertia is important because it reflects the power system's ability to withstand contingencies and maintain frequency security. This paper proposes a practica…
