mongodb - Collection size still very big after delete MogoDb -


i use mongodb hosted on mlab.com

i removed entries before 31th of april using command db.trip.remove({"_created_at":{"$lt":isodate("2017-04-31t10....

that on 40,000 record deleted out of 47,000 in total expecting collection size reduced same percentage. database size became 5.5gb after 7gb , collection size became 4.4 after 6.95.

i tried

db.runcommand({compact: "trip","force":true}); db.repairdatabase();

same problem.

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 ...
