Natural Language Video Processing (Machine Learning-based Identification, Search, Extraction)
The systems and methods described herein provide for a natural-language to generative video process using language-classification and knowledge graph identifiers to find frame segments within a codex of videos that depict the scene described. The mechanics necessary for converting speech to meaningful entities that can be matched to non-text images/videos serve as an underlying basis for generative video
WIDESEAS: A lattice-based PIR scheme implemented in EncryptedQuery
We introduce the WIDESEAS protocol for
lattice-based Private Information Retrieval (PIR),
and we give performance numbers for its
recent implementation in the EncryptedQuery
open-source PIR software.
This protocol uses the fully homomorphic
Brakerski--Fan--Vercauteren (BFV) encryption scheme,
as opposed to the Paillier scheme, which
is used in all earlier versions of EncryptedQuery.
We show that the homomorphic capabilities
of BFV result in smaller query sizes
(due to a query-shrinking technique
based on batching and ciphertext multiplication),
higher response generation rates
(due to using relinearization to keep
ciphertexts small;
due to caching certain products of query elements
in the NTT domain;
due to using the distributive law to achieve a
quadratic reduction in the total
number of ciphertext multiplications;
due to using lazy reduction to speed up modular
multiplies;
and,
due to exploiting properties of inverse NTTs
over periodic data, and forward NTTs over sparse
data, for the purpose of accelerating plain multiplications),
and
comparable response sizes
(due to using modulus switching to discard redundant
ciphertext information prior to transmitting
the response).
For instance, running a single thread
(with Turbo Boost disabled) on a MacBook Pro
equipped with a 2.8 GHz Intel core i7,
and using a -bit hash and a -byte
data chunk size (which allows us to search
for a single targeted selector),
our implementation can
(i) generate a query of size in around
(ii) process a query against a database
(comprised of -many records)
at a rate of
(which is at least two orders of magnitude
faster than the Paillier-based version
of EncryptedQuery),
and
(iii) generate a response of size
in around
We expect a speed up on server class machines.
Our implementation uses the Microsoft SEAL
library along with a small amount of custom code
Calibration Uncertainty for Advanced LIGO's First and Second Observing Runs
Calibration of the Advanced LIGO detectors is the quantification of the
detectors' response to gravitational waves. Gravitational waves incident on the
detectors cause phase shifts in the interferometer laser light which are read
out as intensity fluctuations at the detector output. Understanding this
detector response to gravitational waves is crucial to producing accurate and
precise gravitational wave strain data. Estimates of binary black hole and
neutron star parameters and tests of general relativity require well-calibrated
data, as miscalibrations will lead to biased results. We describe the method of
producing calibration uncertainty estimates for both LIGO detectors in the
first and second observing runs.Comment: 15 pages, 21 figures, LIGO DCC P160013
