This paper reports on the impact of information asymmetry on product valuation. Symmetric versus asymmetric information was provided to two different groups of subjects. The subjects were then asked to value an information technology product. The study found significant difference in the valuation between two groups. The group with the symmetric information valued the product highly and in clos...

We prove that, in the l-ball of the Cayley graph of the braid group with n > 3 strands, the proportion of rigid pseudo-Anosov braids is bounded below independently of l by a positive value.

We present an algorithm that achieves almost optimal pseudo-regret bounds against adversarial and stochastic bandits. Against adversarial bandits the pseudo-regret is O ( K √ n log n ) and against stochastic bandits the pseudo-regret is O ( ∑ i(log n)/∆i). We also show that no algorithm with O (log n) pseudo-regret against stochastic bandits can achieve Õ ( √ n) expected regret against adaptive...

Actual possession of an item has been shown to increase an owner’s valuation of it, a phenomenon termed the “endowment effect” (Thaler, 1980). We hypothesize that temporarily being the high bidder during an auction induces a “pseudo-endowment effect.” This effect may foster attachment to an item during the auction and thus promote overbidding. We examine this effect in two studies. In the first...

Symmetry detection in 3D images is an important task in many fields such as computer vision, pattern recognition to name a few. An algebraic based 3D symmetry detection algorithm is presented. The 3D volume is transformed to the Fourier domain by using the pseudo-polar Fourier transform. The pseudo-polar representation enables to analyze angular properties such as finite symmetric properties th...

Three equivalence relations are considered on the set of n x n matrices with elements in Fo' an · abelian group with absorbing zero adjoined. They are the relations of diagonal similarity, diagonal equivalence, and restricted diagonal equivalence. These relations are usually considered for matrices with elements in a field, but only multiplication is involved. Thus our formulation in terms of a...
