Complexity is the grand challenge for science and engineering in the 21st century. We suggest that biology is a discipline that is uniquely situated to tackle complexity, through a diverse array of technologies for characterizing molecular structure, interactions and function. A major difficulty in the analysis of complex biological systems is dealing with the low signal-to-noise inherent to nearly all large-scale biological data sets. We discuss powerful bioinformatic concepts for boosting signal-to-noise through external knowledge incorporated in processing units we call Filters and Integrators. These concepts are illustrated in four landmark studies that have provided model implementations of Filters, Integrators, or both.
