Consistent High Dimensional Rounding with Side Information [article]

Orr Dunkelman, Zeev Geyzel, Chaya Keller, Nathan Keller, Eyal Ronen, Adi Shamir, Ran J. Tessler
2020 arXiv   pre-print
We call such a process consistent rounding, and make it possible by allowing a small amount of information about the first measurement X_1 to be unidirectionally communicated to and used by the rounding  ...  When the measurements X_i are arbitrary vectors in R^d, we show that communicating log_2(d+1) bits of information is both sufficient and necessary (in the worst case) in order to achieve consistent rounding  ...  Since we expect these measurements to be slightly different for the infected and exposed persons, the health authority can publish the small amount of side information along with the consistently rounded  ...

A fast compression algorithm for seismic data from non-cable seismographs

Fan Zheng, Shufen Liu
2012 2012 World Congress on Information and Communication Technologies  
Experiments have shown that, at the same compression ratio, the proposed algorithm compresses 30% faster than traditional approach which directly uses two-dimensional wavelet transform to process two-dimensional  ...  First, separate the valid file header and extract the valid data to 4 one-dimensional matrixes.  ...  Low frequency coefficients then underwent several rounds of wavelet transform. A certain level of scalar quantization was applied on high frequency information so as to control the compression ratio.  ...

2005 Nature  
Only by additionally imposing an unlikely high intrinsic viscosity increase to the dense material can rounded superplumes of dense material form.  ...  We find that subduction history tends to focus dense material into a ridge-like pile beneath Africa and a relatively more-rounded pile under the Pacific Ocean, consistent with seismic observations.  ...  Author Information Reprints and permissions information is available at npg.nature.com/reprintsandpermissions.
