android - Firebase update a lot of children value -


suppose have 10000 children in "post" each node contain children "username". if "usera" added 6000 in 10000 of data. how can update "usera" in every node in "post"

firebase

you need know user posts.

you need structure :

root  |  +-- posts  |     |  |     +-- $postid  |           |  |           +-- text: $text  |           |  |           +-- username: $username  |  +-- userposts  |     |  |     +-- $userid  |           |  |           +-- $postid: true

with structure can retrieve posts id user , update posts.

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 ...
