An Exact Instrument for State Usage in Selective State-Space Models, and the Input-Driven Migration It Reveals
Raktim Bhattacharya
Selective state-space models such as Mamba route information through a bank of first-order modes whose input coupling is set by a learned selection mechanism. We give an exact inst…
Robust Observer Design via Finsler's Lemma and IQCs
Raktim Bhattacharya, Felix Biertümpfel
This paper develops a Finsler-based LMI for robust observer design with integral quadratic constraints (IQCs) and block-structured uncertainty. By introducing…
Sensor Design for Accuracy-Bounded Estimation via Maximum-Entropy Likelihood Synthesis
Raktim Bhattacharya
Designing the sensing architecture for large-scale spatio-temporal systems is hard when accuracy requirements are specified but sensor models are uncertain or unavailable. Classica…
Improving D-Optimal Sensor Placement for Bearing-Only Localization via Maximum-Entropy Reweighting
Raktim Bhattacharya
In this paper, we present a two-layer architecture for bearing-only sensor placement that improves upon classical D-optimal design. The first layer reweights particles by minimizin…
Optimal Sensing Precision for Celestial Navigation Systems in Cislunar Space using LPV Framework
Eliot Nychka, Raktim Bhattacharya
This paper introduces two innovative convex optimization formulations to simultaneously optimize the H2/Hinf observer gain and sensing precision, and guarantee a specified estimati…
