@IgorCarron blogs recent applications of compressive sensing and matrix factorisation every week.

(Compressive sensing solves underdetermined systems of equations, for example trying to fill in missing data, by L₁-norm minimisation.)

This week: reverse-engineering biochemical pathways and complex systems analysis.
