java - How does Spark's Word2Vec function with regard to the RDD's rows when creating a model? -

after experimenting spark's word2vec code , data text8 provided here word2vec example ended getting java heap errors discussed in spark word2vec example using text8 file . after reading thread came conclusion need break data chunks divided new lines loaded different rdd-rows , not causing java heap errors. njustice said in thread: word2vec works best 1 sentence per row of rdd is so? according knowledge word2vec skip-gram model (used spark) uses window create training samples, for-example text: the black car window size of 2 , the input word generate 2 training samples: (the, black) , (the, car) . but in case data divided rdd-rows, how window behave? able create training samples combining words 2 rows? or run window on each row individually , combine results @ end somehow? doubt works on more 1 rdd-row because created 2 models using same data distributed words differently on rdd-rows , cosine similarity of 2 words different in each model.

sql server - Is there any advantage in creating a clustered index - if we are not going to query/search for records based on that column? -

i doing review of db tables created in our project , came across this. table contains identity column (id) primarykey table , clustered index has been defined using id column. when @ sproc retrieves records table, see id column never used in query , query records based on userid column (this column not unique) , there can multiple records same userid. so question there advantage/purpose in creating clustered index when know records wont queried column? if identity column never used in where , join clauses, or referenced foreign keys, perhaps userid should clustered primary key. question need id column @ in case. the best choice clustered index depends on how table queried. if majority of queries userid, should unique clustered index (or clustered unique constraint) , id column non-clustered. keep in mind clustered index key implicitly included in non-clustered indexes row locator. implication non-clustered indexes may more cover queries , non-clustered index lea...

How to retrieve the package and class info for an argument function in Scala? -

is there way full package , class info/names function passed argument? imagine following case: package mypackage class myclass { def func(a: int): int = { * } def getpackageinfo(f: int => int): string = { // return package , class name of f } } in case invoking getpackageinfo(func) somewhere in myclass should return mypackage.myclass.func . i aware f might anonymous function not belong class, handled check. i don't mind changing signature of getpackageinfo , long can accept methods , return package , class info. a normal function can't it, because if write getpackageinfo(func) compiler expands anonymous function: definition it's same getpackageinfo(func _) same getpackageinfo(x => func(x)) . information want not stored in f , there no way out. but can using macro. https://github.com/dwickern/scala-nameof should useful starting point modify: it'll give func instead of mypackage.myclass.func .
