A Round-Collapse Theorem for Computationally-Sound Protocols; or, TFNP is Hard (on Average) in Pessiland
TFNP round-collapse average-case hardness
2019/6/26
This result follows from a more general theory of interactive average-case complexity, and in particular, a novel round-collapse theorem for computationally-sound protocols, analogous to Babai-Moran's...
Rise In Severity Of Hottest Days Outpaces Global Average Temperature Increase（图）
Hottest Days Outpaces Global Average Temperature Increase
2018/2/1
While our planet’s average annual temperature has increased at a steady pace in recent decades, there has been an alarming jump in the severity of the hottest days of the year during that same period,...
Non-Malleable Codes from Average-Case Hardness: AC0, Decision Trees, and Streaming Space-Bounded Tampering
non-malleable codes streaming
2017/11/3
We show a general framework for constructing non-malleable codes against tampering families with average-case hardness bounds. Our framework adapts ideas from the Naor-Yung double encryption paradigm ...

Louisiana wetlands struggling with sea-level rise four times the global average
Louisiana wetlands struggling sea-level rise four times global average
2017/3/30
Without major efforts to rebuild Louisiana’s wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-l...
We present functions that can be computed in some fixed polynomial time but are hard on average for any algorithm that runs in slightly smaller time, assuming widely-conjectured worst-case hardness fo...
Biotin bioavailability and estimated average requirement: why bother?
Biotin bioavailability
2016/5/30
Frank, symptomatic biotin deficiency probably occurs rarely.
The only well-documented cases have occurred in association
with total or near total intravenous feeding without biotin supplementation,

On the Necessity of Using Average Cost as a Base for Transfer Price
Multibusiness enterprise OECD taxation guidelines Transfer pricing Vertical integration
2016/1/26
Both older and recent literature on transfer pricing is not unified about the opinion whether optimal transfer price should be equal to marginal cost of supplying company and set by centralized decisi...
FUNCTIONAL COEFFICIENT MOVING AVERAGE MODEL WITH APPLICATIONS TO FORECASTING CHINESE CPI
Moving Average model functional coefficient model fore- casting Consumer Price Index
2016/1/26
This article establishes the functional coefficient moving average mod-el (FMA), which allows the coefficient of the classical moving average model to adapt with a covariate. The functional coefficien...
Forecasting Equity Premium: Global Historical Average versus Local Historical Average and Constraints
Equity premium Nonparametric local historical average model Positivity con- straint Bagging
2016/1/25
The equity premium, return on equity minus return on risk-free asset, is expected to be positive. We consider imposing such positivity constraint in local historical average (LHA) in nonparametric ker...
Structural Lattice Reduction: Generalized Worst-Case to Average-Case Reductions and Homomorphic Cryptosystems
Lattices Worst-case to Average-case Reductions Homomorphic Encryption
2016/1/23
In lattice cryptography, worst-case to average-case reductions rely on two problems: Ajtai’s SIS and Regev’s LWE, which both refer to a very small class of random lattices related to the group G = Z...

Equity premium Nonparametric local historical average model Positivity con- straint Bagging Model averaging
2016/1/20
The equity premium, return on equity minus return on risk-free asset, is expected to be positive. We consider imposing such positivity constraint in local historical average (LHA) in nonparametric ker...
Qualification of Close Range Photogrammetry Cameras by Average Image Coordinates RMS Error VS. Object Distance Function
Close Range Accuracy analysis Non-metric camera
2015/12/14
In this publication, the concept of image coordinate RMS error derived from average object side RMS is introduced. In the course of
derivation, data on network geometry and redundancy were taken into...
Sometimes Average is Best:The Importance of Averaging for Prediction using MCMC Inference in Topic Modeling
Sometimes Average is Best Averaging for Prediction MCMC Inference Topic Modeling
2015/9/2
Markov chain Monte Carlo (MCMC) approximates the posterior distribution of latent variable models bygenerating many samples and averaging over them. In practice, however, itis often more convenient to...
Average and Randomized Communication Complexity
Average Randomized Communication Complexity
2015/8/14
The communication complexity of a two-variable function f(x, y) is the number of information bits two communicators need to exchange to compute f when, initially, each knows only one of the variables....
