encog - Using neural network with true and false outputs -


since i'm new neural network, there few questions ask understand more clearly.

  • q1: test true/false results (pattern recognition), mean output layer have 2 neutrons?
  • q2: continue question 1, if in training data, contains true data, result in testing data true? (since i'm having problem, , encog library not allow me specify 2 output neutrons since have 1 type of output in training data).

my training data:

1,2,3,4 pattern1 6,7,8,9 pattern1

my testing data:

4,3,2,1 pattern2

this result got encog: neural network results:

0.0,0.0, actual=-0.05972914453206861,ideal=1.0

can please show me wrong ?
thank much.

if need true/false response, output layer should have one neuron. if 1 neuron active, treat true. if not active, treat false.

if training data has true values bad data, , won't help. end training network respond true. perhaps should figure out data should lead false result , add training data.

if training data has 2 cases, , both true, network isn't going learn anything. need lot more data make pattern clear.

go ask smart person (the best neural networks we've got) following question:

1,2,3,4 true; 6,7,8,9 true. 4,3,2,1 true?

they have no idea. don't know. no 1 knows. don't know criteria is. number of things determines whether sequence true. including:

  • the numbers going up
  • they move in same direction
  • they 1 apart
  • that numbers under 10

i have no idea of these requirements , aren't. no idea. , neural network making have less of idea.

the main problem need more data.

one last note. said neural networks @ 'pattern matching'. , true. however, sequences of numbers aren't meant 'pattern matching'. requires arithmetic isn't going served neural network. aren't exact enough arithmetic. never going able train neural network particularly to, example, identify sequence of doubling numbers.

php - SPIP: From Tag directly to an article -

i work spip , plugin called tagsphere works fine tags in spip. have tag groupe put 1 article tag. when click on tag in tagsphere send me before menu can see articles linked tag. want send me directly article without see tag menu before. here code model of thagsphere: <div id="tagsphere-#env{id_article}"> <ul> <boucle_mot(mots){id_groupe ?}> <li>[<a href="#url_mot">(#titre)</a>]</li> </boucle_mot> </ul> </div> anybody idea? if want skip tag page, have link directly article. <b_article> block prevents display tag if no article linked. <div id="tagsphere-#env{id_article}"> <ul> <boucle_mot(mots){id_groupe ?}> <b_article> <li> <a<boucle_article(articles){...

ruby on rails - In a controller spec, how to find a specific tag in the generated view? -

i know integration tests preferred need ran in controller test, i'm testing gem injecting html code in view, xhr can't run in feature spec (if can, please explain me how :) ) so rspec controller tests can assert selector present (with capybara) : response.body.should have_selector('#foobar') has_selector? call all method capybara find selector. what want last child of body , assert id in particular. afaik it's not possible have_selector. what : all('body:first-child').first.id.should == '#foobar' however, capybara dsl, defined (more or less): def all(*args) page.all(*args) end and page empty unless use visit it's integrations specs. how can use capybara all method inside rspec controller test ? i can't test right after googling seems trick def page capybara::node::simple.new(response.body) end source
