On the other hand, although the proposed approach need to search vectors for the words within candidate extractions to compute the confidence score, the word vectors are stored in
hashtable, which ensures the high efficiency over REVERB.
system of selecting a user's playlist from a "
hashtable"
Some basic operations involved in this algorithm (and in Algorithm 2 and 3) include operation over stack, operation over
hashtable and operation over vector.
Hashtable to store the relationship between customers and countries.
As shown, although the execution time of the first pass of EH-Apriori is slightly larger than that of E-Apriori, due to the extra overhead required for building
HashTable, EH-Apriori incurs significantly smaller execution time than E-Apriori in the latter Pass 2, as |[C.sub.2]| is decreased greatly from 270355 to 115 by means of hash filtering (at T5-I3-W3-N1000-D100K, minimum support = 0.7%).
function hash (K: keytype; T:
hashtable): integer; const prime = 1048583; var h, address: integer; begin h:=convertkey(K) mod prime; address:=h mod T.maxp; if address<T.p then address:=h mod(2*T.maxp); hash:=address; end;
Finally, the value which included the
hashtable was inserted into the database system using the SQL query.
Similar to a traditional
hashtable data structure, other operations supported in the DHT include put and get.
Perhaps the bottleneck may be a synchronized "
Hashtable" that contains a list of currency exchange rate information for the current day.
The hash table itself,
hashtable, is an array of pointers to word structures: #define HASHSIZE 07777 /* hash table size */ struct word [ char *word; /* the word */ int count; /* frequency count */ struct word *next; /* link to next entry */ ] *hashtable [HASHSIZE+1];
