Interactive privacy via the median mechanism
NettetNot only our algorithms but also most known private algorithms can be implemented using only statistical queries and hence are constrained by these lower bounds. Our result therefore isolates the complexity of agnostic learning in the SQ model as a new barrier in the design of differentially private algorithms. Keywords differential privacy NettetFirst, we’ll give the \Median Mechanism". It won’t operate on sequences of data sets, but instead on sequences of \median data structures": De nition 8 (Median Data Structure) A median data structure D is a collection of databases: D ˆ NjXj. Any query Qcan be evaluated on a median datastructure as follows: Q(D) = Median(fQ(D) : D2Dg). 8-2

NettetResults: The median expression rate of PD-L1 was 5% and 30% in tumor and immune cells, respectively. Patients with higher expression of PD-L1 in tumor cells had shorter disease-free and overall survival, and the HRs were 1.52 for relapse (95% CI: 0.88, 2.60) and 1.48 for death (95% CI: 0.82, 2.69). There was no significant association between ... NettetThis new release mechanism gives an improvement on prior work in a range of parameters where the size of the database is comparable to the size of the data universe (such as releasing all cut queries on dense graphs). We also give a non-interactive algorithm for efficiently releasing private synthetic data for graph cuts with error O ( V …
NettetOur result is almost tight because it is known that Ω ~ ( n 2) counting queries can be answered efficiently while satisfying differential privacy. Moreover, many more than n 2 queries (even exponential in n) can be answered in exponential time. We prove our results by extending the connection between differentially private query release and ...
