While streaming algorithms are often motivated by the constraints due to "big data," in practice this data is not ''static'': however, most streaming algorithms use the structure and regularities encountered in the stream to compute solutions or results only available at the end of the streaming, in hindsight. |

(Note that, in contrast to the majority of the machine learning literature, one cannot in general make the assumption of stochasticity; the performance thus has to be compared in the adversarial setting, or an intermediate, better suited model has to be developed.) |
