Before revision:  However, in a Big Data setting computing the dominant singular vectors is often restrictive due to the main memory requirements imposed by the dataset . Recently introduced randomized projection schemes attempt to mitigate this memory load by constructing approximate projections of the true dataset in a streaming setting.
