Deep Brain Stimulation of the Subthalamic Nucleus Induces Impulsive Responses to Bursts of Sensory Evidence

open access: yesFrontiers in Neuroscience, 2019
Decisions are made through the integration of external and internal inputs until a threshold is reached, triggering a response. The subthalamic nucleus (STN) has been implicated in adjusting the decision bound to prevent impulsivity during difficult ...

On the Depth of Deep Neural Networks: A Theoretical View

open access: yes, 2015
People believe that depth plays an important role in success of deep neural networks (DNN). However, this belief lacks solid theoretical justifications as far as we know. We investigate role of depth from perspective of margin bound.

Dark Atoms of Dark Matter and their Stable Charged Constituents

open access: yes, 2011
Direct searches for dark matter lead to serious problems for simple models with stable neutral Weakly Interacting Massive Particles (WIMPs) as candidates for dark matter. A possibility is discussed that new stable quarks and charged leptons exist and are

A branch-and-bound algorithm to minimize total tardiness in a two-machine flowshop problem with different release time

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
In this study, we consider the scheduling problem for two-machine flowshops with jobs of the different release times. In many real situations, jobs can be arrived at different times due to progress of jobs in the preceding stage or the status of supply ...

Estimates of the optimal density and kissing number of sphere packings in high dimensions

open access: yes, 2007
The problem of finding the asymptotic behavior of the maximal density of sphere packings in high Euclidean dimensions is one of the most fascinating and challenging problems in discrete geometry. One century ago, Minkowski obtained a rigorous lower bound

Influence of Lipschitz bounds on the speed of global optimization

open access: yesTechnological and Economic Development of Economy, 2012
Global optimization methods based on Lipschitz bounds have been analyzed and applied widely to solve various optimization problems. In this paper a bound for Lipschitz function is proposed, which is computed using function values at the vertices of a ...

Improved Bounds for Testing Juntas [PDF]

open access: yes, 2008
We consider the problem of testing functions for the property of being a k-junta (i.e., of depending on at most kvariables). Fischer, Kindler, Ron, Safra, and Samorodnitsky (J. Comput. Sys. Sci., 2004) showed that $\tilde{O}(k^2)/\epsilon$ queries are sufficient to test k-juntas, and conjectured that this bound is optimal for non-adaptive testing ...
