While HPC and cloud computing users may initially be nervous about using lossy compression, they should also remember the compelling benefit of lossy compression: a controllable way to reduce ...

A team of researchers at ETH Zurich are working on a novel approach to solving increasingly large graph problems. Large graphs are a basis of many problems in social sciences (e.g., studying human ...

Lossy compression schemes can be based on a source model, as in the case of speech compression, or a user or sink model, as is somewhat the case in image compression. In this chapter we look at audio ...
