【Abstract】 This paper discusses the effect of side information on Rényi entropy,and gives the upper bounds of the reductions of Rényi entropy with respect to uniform distributions and general distributions At last,a more general upper bound is deduced with the help of Rényi entropy of order 2 and order3 of the side information更多还原
