This paper proposes new method for object reference which enables a person to find surrounding objects and develops a navigation system named CoCo. CoCo employs an ultrasonic direc...
There exists a positive constant α < 1 such that for any function T(n) ≤ nα and for any problem L ∈ BPTIME(T(n)), there exists a deterministic algorithm running in poly(T...
A halfspace matrix is a Boolean matrix A with rows indexed by linear threshold functions f, columns indexed by inputs x ∈ {−1,1}n, and the entries given by Af,x = f(x). We dem...
We prove new results on the circuit complexity of Approximate Majority, which is the problem of computing Majority of a given bit string whose fraction of 1's is bounded away...
A t-design for quantum states is a finite set of quantum states with the property of simulating the Haar-measure on quantum states w.r.t. any test that uses at most t copies of a...
