Do Better Scores Mean Better Physics? Physics-Grounded Explanations for Sim2Real Neural Operators
Somyajit Chakraborty, Xizhong Chen
Machine-learning surrogates accelerate physical simulation, but lower prediction error need not coincide with lower error in physically relevant flow statistics. We examine this qu…
A Spectral Identifiability Threshold for Dissipative Rate Recovery from Truncated Liouvillian Spectra
Yujun Ji, Somyajit Chakraborty
Open quantum systems lose energy and phase coherence through different dissipative processes, but these processes can produce overlapping dynamical signatures. The Liouvillian spec…
A Physics-Informed Fourier-Wavelet Transformer for Multiscale Computational Fluid Dynamics Surrogate Modeling
Somyajit Chakraborty, Ming Pan, Xizhong Chen
Physics-informed surrogate models can accelerate computational fluid dynamics simulations. However, many existing methods reproduce global flow patterns more reliably than localize…
A Co-Evolutionary Theory of Human-AI Coexistence: Mutualism, Governance, and Dynamics in Complex Societies
Somyajit Chakraborty
Classical robot ethics is often framed around obedience, including Asimov's laws. This framing is insufficient for contemporary AI systems, which are increasingly adaptive, generat…
Bridging Through Absence: How Comeback Researchers Bridge Knowledge Gaps Through Structural Re-emergence
Somyajit Chakraborty, Angshuman Jana, Avijit Gayen
Understanding the role of researchers who return to academia after prolonged inactivity, termed "comeback researchers", is crucial for developing inclusive models of scientific car…
Trust@Health: A Trust-Based Multilayered Network for Scalable Healthcare Service Management
Avijit Gayen, Somyajit Chakraborty, Joydeep Chakraborty +1
We study the intricate relationships within healthcare systems, focusing on interactions among doctors, departments, and hospitals. Leveraging an evolutionary graph framework, the…
LLMPR: A Novel LLM-Driven Transfer Learning based Petition Ranking Model
Avijit Gayen, Somyajit Chakraborty, Mainak Sen +2
The persistent accumulation of unresolved legal cases, especially within the Indian judiciary, significantly hampers the timely delivery of justice. Manual methods of prioritizing…
