High-dimensionality
Web4 High dimensionality. Big data in genomics is characterized by its high dimensionality, which refers both to the sample size and number of variables and their structures. The pure volume of the data brings challenges in data storage and computation. The data volume can be on the order of terabytes for just the raw data of each sample. Web20 de mai. de 2014 · $\begingroup$ "high dimensions" seems to be a misleading term - some answers are treating 9-12 as "high dimensions", but in other areas high dimensionality would mean thousands or a million dimensions (say, measuring angles between bag-of-words vectors where each dimension is the frequency of some word in a …
