statistics - How to know one system is siginficantly better than another one? -

-

i studying lexical semantics. have 65 pairs of synonyms sense relatedness. dataset derived paper:

rubenstein, herbert, , john b. goodenough. "contextual correlates of synonymy." communications of acm 8.10 (1965): 627-633.

i extract sentences containing synonyms, transfer neighbouring words appearing in sentences vectors, calculate cosine distance between different vectors, , pearson correlation between distances calculate , sense relatedness given rubenstein , goodenough

i pearson correlation method 1 0.79, , method 2 0.78, example. how measure method 1 better method 2 or not?

well strictly not programming question, since question unanswered in others stackexchange sites, i'll tell approach take.

i there other benchmarks check approaches on similar tasks. can check how method performs on benchmarks , analyze results. methods may capture similarity more while others relatedness , both.

this link wordvec demo automatically scores vectors , provides results.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
