Charging up the functional bootstrap [PDF]

Journal of High Energy Physics, 2021
We revisit the problem of bootstrapping CFT correlators of charged fields. After discussing in detail how bounds for uncharged fields can be recycled to the charged case, we introduce two sets of analytic functional bases for correlators on the line. The

Bootstrapping covariance operators of functional time series [PDF]

Journal of Nonparametric Statistics, 2020
For testing hypothesis on the covariance operator of functional time series, we suggest to use the full functional information and to avoid dimension reduction techniques. The limit distribution follows from the central limit theorem of the weak convergence of the partial sum process in general Hilbert space applied to the product space.

A multimodal MRI framework employing machine learning for detecting beginning cognitive impairment in Parkinson’s disease [PDF]

Frontiers in Neuroscience
Cognitive deficits affect up to half of the patients with Parkinson’s disease (PD) within a decade of diagnosis, placing an increasing burden on patients, families and caregivers.

Navigator function for the conformal bootstrap [PDF]

SciPost Physics, 2021
Current numerical conformal bootstrap techniques carve out islands in theory space by repeatedly checking whether points are allowed or excluded. We propose a new method for searching theory space that replaces the binary information "allowed"/"excluded" with a continuous "navigator" function that is negative in the allowed region and positive in the ...

The functional bootstrap for boundary CFT [PDF]

Journal of High Energy Physics, 2020
Abstract We introduce a new approach to the study of the crossing equation for CFTs in the presence of a boundary. We argue that there is a basis for this equation related to the generalized free field solution. The dual basis is a set of linear functionals which act on the crossing equation to give a set of sum rules on the ...

Revisiting the functional bootstrap in TFHE

IACR Transactions on Cryptographic Hardware and Embedded Systems, 2021
The FHEW cryptosystem introduced the idea that an arbitrary function can be evaluated within the bootstrap procedure as a table lookup. The faster bootstraps of TFHE strengthened this approach, which was later named Functional Bootstrap (Boura et al., CSCML’19).

FDFB: Full Domain Functional Bootstrapping Towards Practical Fully Homomorphic Encryption

Transactions on Cryptographic Hardware and Embedded Systems, 2022
Computation on ciphertexts of all known fully homomorphic encryption (FHE) schemes induces some noise, which, if too large, will destroy the plaintext.

Differentiable Functionals and Smoothed Bootstrap [PDF]

Annals of the Institute of Statistical Mathematics, 1997
The differentiability properties of statistical functionals have several interesting applications. We are concerned with two of them. First, we prove a result on asymptotic validity for the so-called smoothed bootstrap (where the artificial samples are drawn from a density estimator instead of being resampled from the original data).

Integer-Wise Functional Bootstrapping on TFHE: Applications in Secure Integer Arithmetics

Information, 2021
TFHE is a fast fully homomorphic encryption scheme proposed by Chillotti et al. in Asiacrypt’ 2018. Integer-wise TFHE is a generalized version of TFHE that can encrypt the plaintext of an integer that was implicitly presented by Chillotti et al., and ...
