Sentence examples for hash index from inspiring English sources

Calculates hash index from any char string.

Unlike recent aligners based on the Burrows-Wheeler transform, SNAP uses a simple hash index of short seed sequences from the genome, similar to BLAST's.

Whereas, current state-of-the-art sequence aligner either generate (hash index based) or load (sorted index based) index for every task.

Unlike ZDB which uses an array index to store keys, the FAWN data store uses a hash index to map 160 bit keys to the actual key stored in memory to find a location in the log.

Thirdly, hash index is constructed.

In order to speed up SWA, we use hash index to store the location of each keyword and read rather than the keyword itself in hash index.

In order to also use deterministic indexes against attackers with background knowledge of the data, the flattened hash indexes approach was proposed [10].

For the same reasons as flattened hash indexes, flattened bucketization can be used against D&BKQ-attackers, however it only provides probabilistic database protection.

The basic idea of flattened hash indexes is to map different plaintext values to the same deterministic substitute in such a way that each deterministic substitute occurs the same number of times.

Thus, flattened hash indexes can be used against D&BKQ-attackers, but only provide probabilistic database protection because an attacker with background knowledge may gain information about some of the plaintext values based on the outsourced data.

Although there are some limitations to general hash indexes, the nature of genomic data and the specialized task of mapping paired end reads to a reference genome, allows the use of hash indexes that circumvent these limitations.
