Quantization of prior probabilities in Bayesian group decision-making
(Massachusetts Institute of Technology, 2010)In Bayesian hypothesis testing, a decision is made based on a prior probability distribution over the hypotheses, an observation with a known conditional distribution given the true hypothesis, and an assignment of costs ... -
Quantized Guessing Random Additive Noise Decoding - A Universal Quantized Soft-Decoder
(Massachusetts Institute of Technology, 2022-09)Guessing Random Additive Noise Decoding (GRAND) has proven to be a universal, maximum likelihood decoder. Multiple extensions of GRAND have been introduced, giving way to a class of universal decoders. GRAND itself describes ... -
Quantized multiplicative quiver varieties and actions of higher genus braid groups
(Massachusetts Institute of Technology, 2011)In this thesis, a new class of algebras called quantized multiplicative quiver varieties A (Q), is constructed, depending upon a quiver Q, its dimension vector d, and a certain "moment map" parameter . The algebras Ad(Q) ... -
