Automatic Discovery and Assessment of Interpretable Systematic Errors in Semantic Segmentation
Jaisidh Singh, Sonam Singh, Amit Arvind Kale +1
This paper presents a novel method for discovering systematic errors in segmentation models. For instance, a systematic error in the segmentation model can be a sufficiently large…
QKSA: Quantum Knowledge Seeking Agent -- resource-optimized reinforcement learning using quantum process tomography
Aritra Sarkar, Zaid Al-Ars, Harshitta Gandhi +1
In this research, we extend the universal reinforcement learning (URL) agent models of artificial general intelligence to quantum environments. The utility function of a classical…
Towards Credit-Fraud Detection via Sparsely Varying Gaussian Approximations
Harshit Sharma, Harsh K. Gandhi, Apoorv Jain
Fraudulent activities are an expensive problem for many financial institutions, costing billions of dollars to corporations annually. More commonly occurring activities in this reg…
Ultra-sensitive Light Confinement Driven by Multiple Bound States in the Continuum
Harsh K. Gandhi, Arnab Laha, Somnath Ghosh
We propose a unique framework to study the topological properties of an optical bound state in the continuum(BIC). We employ the interactions between proximity resonances undergoin…
Higher order topological degeneracies and towards unique successive state-switching in a four-level open system
Sayan Bhattacherjee, Harsh K. Gandhi, Arnab Laha +1
The physics of topological singularities, namely exceptional points (EPs), has been a key to wide range of intriguing and unique physical effects in non-Hermitian systems. In this…
Towards Hosting Bound State in Continuum in Specialty Optical Microcavity
Harsh K. Gandhi, Arnab Laha, Somnath Ghosh
We exploit the interaction between supported proximity resonances in an open non-uniformly pumped optical microcavity to host a Bound State in Continuum (BIC). Using the modeling o…
Exceptional Point and Toward Mode Selective Optical Isolation
Arnab Laha, Sibnath Dey, Harsh K. Gandhi +2
Dynamical encirclement of an Exceptional Point (EP) and corresponding time-asymmetric mode evolution properties due to breakdown in adiabatic theorem have been a key to range of ex…
Optical waveguide hosting multiple exceptional points: Toward selective mode conversion
Arnab Laha, Harsh K. Gandhi, Sibnath Dey +3
We investigate the astonishing physical aspects of Exceptional Points (EPs) in a 1D planar few-mode optical waveguide. The waveguide hosts four quasi-guided modes. Here interaction…
Propagation and asymmetric behavior of optical pulses through time-dynamic loss-gain assisted media
Piyali Biswas, Harsh K. Gandhi, Vaibhab Mishra +1
We report an asymmetric behavior of optical pulses during their propagation through a time-varying linear optical medium. The refractive index of the medium is considered to be var…
