    Dask has two parts: [13] Big data collections (high level and low level) Dynamic task scheduling; Dask's high-level parallel collections – DataFrames, [14] Bags, [15] and Arrays [16] – operate in parallel on datasets that may not fit into memory. Dask’s task scheduler [10] executes task graphs in parallel. It can scale to thousand-node ...

  4. Flajolet–Martin algorithm - Wikipedia

    en.wikipedia.org/wiki/Flajolet–Martin_algorithm

    A common solution is to combine both the mean and the median: Create hash functions and split them into distinct groups (each of size ). Within each group use the mean for aggregating together the l {\displaystyle l} results, and finally take the median of the k {\displaystyle k} group estimates as the final estimate.

    en.wikipedia.org/wiki/Word2vec

    Word2vec was created, patented, [7] and published in 2013 by a team of researchers led by Mikolov at Google over two papers. [1] [2] The original paper was rejected by reviewers for ICLR conference 2013. It also took months for the code to be approved for open-sourcing. [8] Other researchers helped analyse and explain the algorithm. [4]

  6. Merge algorithm - Wikipedia

    en.wikipedia.org/wiki/Merge_algorithm

    A graph exemplifying merge sort. Two red arrows starting from the same node indicate a split, while two green arrows ending at the same node correspond to an execution of the merge algorithm. The merge algorithm plays a critical role in the merge sort algorithm, a comparison-based sorting algorithm. Conceptually, the merge sort algorithm ...

  7. Merge (SQL) - Wikipedia

    en.wikipedia.org/wiki/Merge_(SQL)

    A relational database management system uses SQL MERGE (also called upsert) statements to INSERT new records or UPDATE or DELETE existing records depending on whether condition matches. It was officially introduced in the SQL:2003 standard, and expanded [ citation needed ] in the SQL:2008 standard.
