postgresql - hibernate enverse : how to get changed value in relation field -


i using hibernate enverse 5.2.10.final postgres data base.

auditreader auditreader = auditreaderfactory.get(entitymanager);         string newvalue = (string) auditreader.createquery()                 .forentitiesatrevision(vehicle.class, 2203869)                 .traverserelation("vehicletype", jointype.inner).addprojection(auditentity.property("id")).up()                 .add(auditentity.property("vehicletype").haschanged())                               .add(auditentity.id().eq(2203422l))                 .add(auditentity.revisionnumber().eq(2203869)).getsingleresult();

vehicle table has many-to-one relationship vehicletype. how changes of vehicle type property of vehicle entity using enverse query. here no result found error. cannot get value audientity.property("vehicletype")..haschanged() their's error property not found.

auditreader.createquery()   .forentitiesatrevision( vehicle.class, revisionnumber )                                              .traverserelation( propertyname, jointype.left )   .addprojection( auditentity.property("id") ).up()   .add( auditentity.property( propertyname ).haschanged() )   .add( auditentity.id().eq( vehicleid ) )                                     .getsingleresult()

javascript - Training Neural Network to play flappy bird with genetic algorithm - Why can't it learn? -

Image
i have been learning neural networks , genetic algorithms, , test learning, have tried make ai learns play flappy bird: i have left running @ least 10 hours (overnight , longer), fittest member still fails show significant advancements in intelligence when began simulation apart avoiding floor , ceilings. inputs rays (as can see above) act sight lines, , network fed in lengths, , birds vertical velocity. seems best bird ignoring sight lines except horizontal one, , when short, jumping. output number between 0 , 1, if output larger 0.5, bird jumps. there 4 hidden layers, 15 neurons each, input layer feeding forward first hidden layers, 1st hidden layer feeding forward 2nd 1 ... , final hidden layer feeding forward output, dna of bird array of real numbers representing weights of neural networks, have made project using same style of neural network, , genetic algorithm, in ants had travel food, , worked perfectly. here code: https://github.com/karan0110/flappy-bird-ai please ...
